1. Added more checks for cases where dragging a block from the drawer
results in many blocks being created at the same (x, y)
coordinates. (see mit-cml/blockly master)

2. Fixed issue where error checking did not occur when deleting a
global variable definition block.

3. Fixed issue introduced in extension update that prevented deleting
extensions from projects imported before the update.

This commit addresses two issues with the blockly update:

1. Updates the flyout implementation in Blockly core to store
information about the last created block so that if many create
operations are fired only the first will be applied. This should
prevent a reported issue where many blocks are created at exactly the
same location when dragging from the flyout.

2. Change the z-index of ode-DialogBox to be greater than Blockly's
drag surface z-index so that dialogs that appear during drag
operations will not be occluded by the dialog. Prior to this change,
the block would be above the dialog and prevent the user from being
able to click any button to dismiss the dialog.

This commit fixes some logic bugs in the ComponentServiceImpl changes
for the IOT release related to the inclusion of multiple extensions
per aix and the fact that component.json was renamed to
components.json to reflect this.

This commit also adds unit tests to evaluate the different code paths
through the ComponentServiceImpl to ensure correctness of different
upgrade paths.

This is a squashed commit containing bugfixes for the Blockly
update. The individual commit bodies are below as a summary:

1. After using the Paste All Blocks from Backpack menu item, undoing
this operation requires N Undo commands whereas it should only require
1 Undo. This commit wraps the bulk of the pasteBackpack operation in a
try-finally to set/unset the Blockly event group so that all of the
create block events are grouped together.

2. Prevent CSS updates during paste all from backpack

3. Ghica reported that when the backpack is open it is possible to
scroll both the flyout's and workspace's scrollbars and there is no
visual indicator which is which. This means that sometimes the user
will scroll the workspace when intending to scroll the flyout. This
commit makes flyouts hide their parent workspace's scrollbars and show
them after the flyout is dismissed.

4. Improve rendering of flyouts with many blocks

5. Hide backpack with ESC key

6. Only fire parameter orientation event after orientation change

7. The implementation of Blockly.Events.filer on Google's master is
implemented using a O(n^2) algorithm. When performing operations that
affect a large number of blocks, e.g. arrangements or pasting from the
Backpack, this performance is unacceptable. This commit provides a new
implementation of Blockly.Events.filter that is linear in the number
of pending events.

8. Removing mutators for parameters or deleting the procedure block
and then attempting to undo the operation would leave the caller
blocks in an inconsistent state with missing parameters or not
reconnecting the previously attached input blocks. This commit fixes
these issues by changing the order of certain operations so that when
Blockly reverses the order of operations variables, such as the caller
block's PROCNAME, are set correctly.

9. The way that Blockly handles changes to fields breaks how we
renamed parameters in the mutator. This commit provides a custom
handler for key events that makes the renaming behavior match that
before the Blockly update.

10. Cherry-picked code for mutators that fixed the ordering of the
mutator workspace's toolbox with respect to the block canvas.

11. Fixed delete area not appearing for the mutator workspace.

12. Fixed ghost scrollbars from different flyouts capturing the mouse
over event for blocks in the drawer flyout.

13. Made it so that dragging a block in any direction from a flyout
will result in a new block being created. Previously the window was
±70 degrees from the horizontal axis.

14. Improved performance on large projects during load or after moving
a stack of blocks.

15. Fixed error checking on blocks created by typeblock and their
relatives.

16. Fixed null pointer exception when renaming a component prior to
opening the blocks editor.

17. Moved updates to the scrollbar visibility to setScrollbarsVisible
and made all changes to scrollbar visibility go through that method,
which includes fix 16 above.

18. Made arrangement options adjust to workspace scale and
snap-to-grid options.

19. Fixed issue where changing text fields would not result in a
Change event and therefore fail to trigger a workspace save.

20. Added fix to ensure the warning handler exists before attempting
to do error checks on variables.

21. Patched Blockly code to prevent the connection database from
throwing an error when an operation would essentially be an identity
operation on the database.

The buildserver should return an error if Kawa cannot compile the YAIL
file. However, on Windows we end up always pointing at the classes
directory, which always exists, and therefore we continue compiling an
app even though the class files are missing. On Mac/Linux the same
project results in a Kawa compilation error. The logic error is
introduced by the hard coding of the path "/../src/" in
Compiler.java. On Windows the path uses the conventional Windows
separator "\\", so the substring of interest is "\\..\\src\\". This
commit adjusts the lookup string to use File.separator so that the
lookup path will be correct regardless of platform.

Javac default output format for files is platform-specific. In the
ai.apt macro we do not specify the encoding, so we end up with
ISO-8859-1 strings on Windows that GWT later attempts to decode as
UTF-8 strings. This commit sets the encoding for the javac command to
be UTF-8 so that encodings work correctly on platforms (e.g., Windows)
where the default encoding is not UTF-8.

Extensions loaded into App Inventor have "More Information" URLs based
on the server's documentation. Obviously, we won't have documentation
for every single extension, nor do we want to update the GAE
application every time someone publishes or updates an extension. This
commit adds a new helpUrl field to the `@DesignerComponent` annotation
that can be used to specify a custom URL for extension documentation.

Closes issue #883.

For the Internet of Things update, we want to be able to have
collections of related extensions, for example, targetting different
features of the same platform, to be imported as a single unit. This
behavior reflects how we group components such as the LEGO EV3 or NXT
robots and allows us to treat extensions in the same way.

For the Internet of Things update, we want to allow extensions to
specify restrictions on designer properties. Specifically, we want IOT
extensions with a BluetoothDevice property to be able to restrict the
component list to the BluetoothLE extension. This commit extends the
behavior of the component property type by allowing an extension
author to include a colon (":") followed by the fully-qualified class
name of the component type to accept.

The context menu items for arranging blocks and sorting by category
did not have expected behavior due to the new Blockly events
system. This commit introduces two new events StartArrangeBlocks and
EndArrangeBlocks that will manipulate the appropriate flags so the
context menu options work correctly. We also group the arrangement
events in a single group. This makes the undo/redo menu options behave
correctly rather than undoing/redoing individual moves within the
larger arrangement action.

Because Blockly is linked into the GWT JavaScript, goog.ui.Dialog
attempts to show itself on the GWT iframe's document rather than on
the top window where the UI is actually displayed. This commit adds a
goog.ui.DomHelper so that the Dialog attachs its DOM elements to the
correct document.

NB: This has the side-effect that the runtime error dialog from the
companion is now UI global (it will show even if in the designer).

When renaming variables, references to those variables are not
correctly renamed. This is due to a change in the order in which
Blockly manipulates the field's value and calls the validator. Since
the update occurs before validation, we don't know the original name
and therefore cannot find and update all of the references. This
commit provides the flydown with its own implementation of
onHtmlInputChanged_ so that it can provide a behavior that is
compatible with our renaming mechanism, mainly that it will validate
first and only if successful will it update the field's value.

Procedure definitions have the option for horizontal/vertical
orientation of parameters. However, switching resulted in the inputs
disappearing from the block. This was caused by the new fields not
being initialized correctly such that when the block attempted to
redraw, expected SVG elements were undefined.

This commit fixes the updateParams_ method for procedure blocks so
that they will correctly handle switching between the two cases.

A change in Chrome results in different behavior when focusing an
invisible element. When the list is longer than the panel, this

on the GWT Github repository.

When switching between languages, or loading an AIA created in one
language but the user's language is different, the translation of
event parameters would not always hold. This is due to the use of
`eventparam` as a mutation on the lexical getter and setter
blocks. Through certain actions, the `eventparam` cached value could
be reset to an incorrect state.

This commit does two things to address this issue: (1) adds an
`updateMutation()` method that can be used to recompute the value of
`eventparam` after a blocks update, including changing the dropdown or
attaching a new parent. This keeps the `eventparam` up-to-date during
normal operation (previously it was only computed on save). (2)
FieldParameterFlydown caches the untranslated `eventparam` value for
instantiating new blocks within the workspace. Previously they were
created with the value `null`, which has special meaning as a cached
'not an event' value. Now they are created with the correct mutation
at the beginning and with (1) should maintain the correct value.

This commit brings the App Inventor blocks editor current to the
Google's Blockly. As part of the update, some additional
organizational changes were made to the code:

1. Remove old blockly in lib/ and replaces it with a git submodule
2. Remove old closure-library in lib/ and replaces it with a git
   submodule
3. Move AI2-specific Blockly changes out of core where possible

Josh ran into a NullPointerException when receiving a SMS message
using a Pixel running Google Fi. There are a few possible reasons this
could happen:

1. We linked against android.telephony.gms.SmsMessage. If the message
   was formatted as CDMA (3gpp2) then it is possible that the message
   returned is null, resulting in the NPE.

2. Any format other than 3gpp or 3gpp2 will result in the same flow as
   1 if a new format is introduced in the future, or if the format
   were something such as a data packet from Google Voice.

In API 19, there was a new
android.provider.Telephony.Sms.Intents#getMessagesFromIntent
introduced to abstract away extracting SmsMessages from Intents. This
commit uses this API when the SDK is 19 or higher. We also catch NPE
in the broadcast receiver and log it to Logcat to prevent crashing.

We store the backpack in a new “user file” named backpack.xml (the other
user file supported is “android.keystore” for the user’s signing
key). As an optimization we remove the backpack.xml file if we store
“[]” in it (the empty backpack represented as an empty JSON string).

When an obfuscated text is used in an application with memory
pressure, the iteration over the obfuscated string can cause a
NullPointerException to be thrown from gnu.text.CharMap. The CharMap
uses weak references to Char objects to make Chars eq?. However, Kawa
does not check whether the Char returned from the WeakReference.get()
method is null and then attempts to take its intValue(). In
applications where there is little memory pressure the WeakReferences
are unlikely to be GCed so we don't normally observe this erroroneous
behavior.

This commit updates kawa-1.11-modified.jar with a check whether the
Char returned by the WeakReference is null prior to taking the
intValue(). If the Char is null, it will fall through to recreate the
Char and add it to the CharMap.

Limit the number of calls to MockForm.refresh(). This lets a project
with a lot of designer objects load when otherwise the exponential time
and space consumption of repeated and nested calls to refresh() would
cause it to fail to load.

This implementation throttles the calls “locally.” The idea is to limit
the number of calls to 1 every 2 seconds. An alternative implementation
would be to set a flag while a project is loading (which is when this is
a problem) and inhibit all calls to refresh while this flag is set. Then
when the project is no longer loading, clear the flag and do one final
call to refresh. However this would be tricky because loading is
asynchronous and knowing when it is completely finished is
complicated. Such an implementation would be spread over several
modules, and add complexity to the codebase. This change is simpler
because it is limited to one module.

We also add a logging call Ode.CLog to Ode that logs to the developer
console instead of the OdeLog module which logs to the special debug
tab. There are situations where logging to the console is desirable,
like when the problem you are attempting to debug leaves App Inventor
locked up so you cannot see the debug tab!

On phones with smaller memory footprints, the use of InputStream.mark
was causing an IOException to be thrown that resulted in images not
loading. This patch loads the entirety of the image into a byte[] and
then uses that in conjunction with a ByteArrayInputStream to pass the
image around to the multiple interfaces that need it without reloading
the content. This fixes the failure to load many images in the
emulator.

Do not use a transaction when running in the dev server as this causes a
multi-entity group error. This happens because the dev server simulates
the Google Cloud Store using the datastore. If we use a transaction in
create project it winds up covering multiple entity groups. One for our
modifications to the “FileData” kind and a second for the simulated GCS
bucket kind.
