So it's possible to know when an external C function is being called at the
top-level, eg by JavaScript without any intermediate C->JS->C calls.

Instead of raising KeyError.  These semantics match JavaScript behaviour
and make it much more seamless to pass Python dicts through to JavaScript

This adds a new undefined singleton to Python, that corresponds directly to

This reverts part of commit fa23e4b0, to
make it so that Python `None` converts to JavaScript `null` (and JavaScript
`null` already converts to Python `None`).  That's consistent with how the
`json` module converts these values back and forth.

When a fatal error occurs it's important to know which precise version it
occurred on in order to be able to decode the crash dump information such
as the backtrace.

By wrapping around the built-in IDF panic handler we can print some extra
information whenever a fatal error occurs.  The message links to a new wiki
page which contains additional information on how to debug ESP32 issues,
and links to the bug reporting issue template.

Fixes automatic baudrate calculation results.

Default clock source on this SoC is HSE not PCLK1.  We could fix this by
switching to PCLK1 instead, but two extra complications:

- PCLK1 on this board is a 42.5MHz and the Pyboard CAN sample_point
  calculation requires an exact match, which is harder to hit with this
  source frequency.

- Would be a breaking change for any existing Python code on this board,
  i.e. specifying brp, bs1, bs2 to initialise CAN.

In the future it might be worth looking switching to the PLL source on this
SoC instead, as this is a much higher frequency that would give higher
quality BRS bitrate matches (probably too high without using the second
divider going into the CAN peripheral though, so more code changes needed
also).

And change Py None conversion so it converts to JS undefined.

The semantics for conversion of these objects are then:
- Python None           -> JavaScript undefined
- JavaScript undefined  -> Python None
- JavaScript null       -> Python None

This follows Pyodide:

This commit defines a new `JsException` exception type which is used on the
Python side to wrap JavaScript errors.  That's then used when a JavaScript
Promise is rejected, and the reason is then converted to a `JsException`
for the Python side to handle.

This new exception is exposed as `jsffi.JsException`.

Only when dynamic USB devices are enabled.

The issue here is that when the USB reset triggers, the dynamic USB device
reset callback is called from inside the TinyUSB task.

If that callback tries to print something then it'll call through to
tud_cdc_write_flush(), but TinyUSB hasn't finished updating state yet to
know it's no longer configured. Subsequently it may try to queue a transfer
and then the low-level DCD layer panics.

By explicitly stalling the endpoint first, usbd_edpt_claim() will fail and
tud_cdc_write_flush() returns immediately.

The W5100 and W5100S only have 4 available sockets and 16kB of socket
buffer.  Allocating 16kB to either the receive or transmit buffer of a
single socket is not allowed, so the current setup does not change the
allocation for socket 0 from the reset default.  ctlwizchip is returning -1
to indicate the error, but the response isn't being inspected and probably
doesn't need to be.

Signed-off-by: Damien George <damien@micropython.org>

The calculations `num_word32 / 4` and `num_word32 / 8` were rounding down
the number of words to program to flash, and therefore possibly truncating
the data (eg mboot could miss writing the final few words of the firmware).

That's fixed in this commit by adding extra logic to program any remaining
words.  And the logic for H5 and H7 is combined.
