Since c80e7c14 changed the GC heap to use
all unused RAM, there is no longer any RAM available for the traditional C
heap (which is not used by default in MicroPython but may be used by C
extensions).  This commit adds a provision for a board to reserve RAM for
the C heap, by defining MICROPY_C_HEAP_SIZE.

The previous code worked on ESP32 but not ESP32-S3.  All the IDF (v4.4.3)
examples call rmt_set_tx_loop_mode before rmt_write_items, so make that
change here.

The att_flags for descriptors does not use the same bitfield as for
characteristics. This was leading to NimBLE descriptors getting the wrong
flags set.

This allows gatts_write(..., send_update=True) to work, which will send
notifications/indications to subscribed clients.

btstack already created the CCCD but writes to it were ignored.

There was no event handler for central-initiated MTU exchange.

Fix truncation of notify/indicate to match NimBLE.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>

btstack only supports central-initiated, so this allows us to have a test
that works on both (ble_mtu.py), and then another one for just the NimBLE
supported behavior (ble_mtu_peripheral.py).

On unix, time.sleep is implemented as select(timeout=<time>) which means
that it does not run the poll hook during sleeping.

This replaces the previous pending operation queue (that used to also be
shared with pending server notify/indicate ops) with a single pending
operation per connection. This allows the value handle to be correctly
passed to the Python-level events.

Also re-structure GATT client event handling to simplify the packet handler
functions.

This adds a mechanism to track a pending notify/indicate operation that
is deferred due to the send buffer being full. This uses a tracked alloc
that is passed as the content arg to the callback.

This replaces the previous mechanism that did this via the global pending
op queue, shared with client read/write ops.

Makes gatts_notify and gatts_indicate work in the same way: by default they
send the DB value, but you can manually override the payload.

In other words, makes gatts_indicate work the same as gatts_notify.

Note: This removes support for queuing notifications and indications on
btstack when the ACL buffer is full. This functionality will be
reimplemented in a future commit.

This reverts commit 0613d3e3.

The value of CFG_TUD_CDC_EP_BUFSIZE should match the endpoint size,
otherwise data may stay in the lower layers of the USB stack (and not
passed up to the higher layers) until a total of CFG_TUD_CDC_EP_BUFSIZE
bytes have been received, which may not happen for a long time.

This commit adds support for the `timeout` keyword argument to machine.I2C
on the rp2 port, following how it's done on other ports.

The main motivation here is avoid the interpreter crashing due to infinite
loops when SDA is stuck low, which is quite common if the board gets reset
while reading from an I2C device.

A default timeout of 50ms is chosen because it's consistent with:
- Commit a707fe50 which used a timeout of
  50,000us for zero-length writes on the rp2 port.
- The machine.SoftI2C class which uses 50,000us as the default timeout.
- The stm32 port's hardware I2C, which uses 50,000us for
  I2C_POLL_DEFAULT_TIMEOUT_US.

This commit also fixes the default timeout on the esp32 port to be
consistent with the above, and updates the documentation for machine.I2C to
document this keyword argument.

The mpremote REPL can now be closed with either ctrl+] or ctrl+x, which
gives users a choice, useful if the ']' key is difficult to access.

Fixes issue #11197.

If a board defines a custom bootloader entry function it will be called
first, if not and the ROM API supports RUN bootloader API, then
`machine.bootloader()` will jump to the ROM serial downloader in USB mode.

This commit allows boards to disable Ethernet and keep the networking stack
enabled, to use an alternate networking interface, such as WiFi.

Note that the `network` and `socket` modules are now enabled by default for
a board.

This commit is necessary to make MicroPython work on this eval kit out of
the box, as the eval kit ships with the HyperFlash physically disconnected
from the bus (refer to the schematics or the user guide) and the QSPI
connected instead, but the fuses/board/pins are configured to boot from
internal flash (on FlexSPI2).

Note that enabling the HyperFlash is not trivial, as it requires soldering
and desoldering of many small footprint resistors and changing fuses.

The GreenHills preprocessor produces #line directives without a file name,
which the regular expression used to distiguish between
"# <number> file..." (GCC and similar) and "#line <number> file..."
(Microsoft C and similar) does not match, aborting processing.

Besides, the regular expression was unnecessarily wide, matching lines
containing a "#", followed by any  number of 'l','i','n', and 'e'
characters.

This adds a new MODE_PYPROJECT, which gives basic support to allow
packaging a small subset of micropython-lib packages to PyPI.

This change allows a package in micropython-lib to:
- Add a "pypi" name to its metadata indicating that it's based on a PyPI
  package.
- Add "stdlib" to its metadata indicating that it's a micropython version
  of a stdlib package.
- Add a "pypi_publish" name to its metadata to indicate that it can be
  published to PyPI (this can be different to the package name, e.g. "foo"
  might want to be published as "micropython-foo").

When a package requires() another one, if it's in MODE_PYPROJECT then if
the package is from pypi then it will record that as a pypi dependency
instead (or no dependency at all if it's from stdlib).

Also allows require() to explicitly specify the pypi name.

Helps prevent the filesystem from getting formatted by mistake, among other
things.  For example, on a Pico board, entering Ctrl+D and Ctrl+C fast many
times will eventually wipe the filesystem (without warning or notice).

Further rationale: Ctrl+C is used a lot by automation scripts (eg mpremote)
and UI's (eg Mu, Thonny) to get the board into a known state.  If the board
is not responding for a short time then it's not possible to know if it's
just a slow start up (eg in _boot.py), or an infinite loop in the main
application.  The former should not be interrupted, but the latter should.
The only way to distinguish these two cases would be to wait "long enough",
and if there's nothing on the serial after "long enough" then assume it's
running the application and Ctrl+C should break out of it.  But defining
"long enough" is impossible for all the different boards and their possible
behaviour.  The solution in this commit is to make it so that frozen
start-up code cannot be interrupted by Ctrl+C.  That code then effectively
acts like normal C start-up code, which also cannot be interrupted.

Note: on the stm32 port this was never seen as an issue because all
start-up code is in C.  But now other ports start to put more things in
_boot.py and so this problem crops up.

The dispatch active flag is only set once and never reset, so it will
always call the dispatch handler (once enabled), and it's not really
needed because it doesn't make things more efficient.

Also remove unused included headers.

Like frame error, overrun, etc.  Fix is provided by @ricksorensen.

It was incomplete.

Changes in this commit:
- Move the pwm_seq array to the p_config data structure.  That prevents
  potential resource collisions between PWM devices.
- Rename the keyword argument 'id' to 'device'.  That's consistent with the
  SAMD port as the other port allowing to specify it.

This regression was introduced by 3d46fe67.

This enables the use of WLAN(0).status('rssi') to get current RSSI of the
AP that the STA is connected to.
