The micro:bit board (and probably other boards using the music or display
module) locked up on soft reboot. Reason was a buffer overflow caused by
an index counter, which was not reset on soft_reboot.
That's fixed in this commit. Tested with a micro:bit board, performing a
series of soft reboots.

This fixes a bug in FrameBuffer.ellipse where it goes into an infinite loop
if both radii are 0.
This fixes the bug with a simple pre-check to see if both radii are 0, and
in that case sets a single pixel at the center. This is consistent with the
behaviour of the method when called with just one of the radii set to 0,
where it will draw a horizontal or vertical line of 1 pixel width.
The pixel is set with setpixel_checked so it should handle out-of-bounds
drawing correctly.
This fix also includes three new tests: one for the default behaviour, one
for drawing out-of-bounds, and one for when the sector mask is 0.
Fixes issue #16053.

- Previously the call to esp_wifi_set_channel() would be immediately
overridden by calling esp_wifi_config(...) with the previous channel set.
- AP interface doesn't seem to need more than esp_wifi_config(...) to work.
It will automatically configure 40MHz bandwidth and place the secondary
channel using similar logic to what was being explicitly calculated here.
- However, calling esp_wifi_set_channel() on the STA interface is necessary
if using this interface with ESP-NOW (without connecting to an AP). So
the esp_wifi_set_channel() call is kept in for this purpose. Without
this, tests/multi_espnow/70_channel.py fails.

Configuring the AP for cyw43 writes to some buffers that are only sent to
the modem when the interface is brought up. This means you can't configure
the AP after calling active(True), the new settings seem to be accepted but
the radio doesn't change.
This is different to the WLAN behaviour on other ports. The esp8266 port
requires calling active(True) on the AP before configuring, even.
Fix this by bouncing the AP interface after a config change, if it's
active. Configuring with active(False) still works the same as before.
Adds a static variable to track interface active state, rather than relying
on the LWIP interface state. This is because the interface state is updated
by a driver callback and there's a race: if code calls active(True) and
then config(a=b) then the driver doesn't know it's active yet and the
changes aren't correctly applied.
It is possible this pattern will cause the AP to come up briefly with the
default "PICOabcd" SSID before being reconfigured, however (due to the
aforementioned race condition) it seems like this may not happen at all
before the new config is applied.

Commit f4ab9d9247 inadvertently broke some
Python block devices, for example esp32 and stm32 SDCard classes. Those
classes return a bool from their `readblocks` and `writeblocks` methods
instead of an integer errno code. With that change, both `False` and
`True` return values are now be interpreted as non-zero and hence the block
device call fails.
The fix in this commit is to allow a bool and explicitly convert `True` to
0 and `False` to `-MP_EIO`.

Seemingly ESP-IDF incorrectly marks RTC FAST memory region

This commit enables the implementation of alternative mbedTLS cryptography
functions, such as ECDSA sign and verify, in pure Python. Alternative
functions are implemented in Python callbacks, that get invoked from
wrapper functions when needed. The callback can return None to fall back
to the default mbedTLS function.
A common use case for this feature is with secure elements that have
drivers implemented in Python. Currently, only the ECDSA alternate sign
function wrapper is implemented.
Tested signing with a private EC key stored on an NXP SE05x secure element.

The LwIP interface is removed in wiznet5k_deinit() which is called as part
of the init sequence. Therefore, if using mDNS, then the interface will
need to be re-added when bringing the interface up.
Additionally, this allows to set the hostname from MicroPython code prior
to bringing the interface up and mDNS responding to the (new) hostname.
This allows the hostname to be configured and saved on the flash or be
based on dynamic information such as the MAC or unique_id().

Getting this test running on stm32- and mimxrt-based boards requires adding
a small delay after constructing the UART so that the initial idle frame
has time to be transmitted before the test starts.
Also, the timing margin needs to account for an additional 1-bit worth of
time on some MCUs.

Some ports (eg stm32) configure the FAT driver differently (eg with

This is a fix for issue #15944, and handles corner cases in the FrameBuffer
code when using stride values where the last line's stride may extend past
the end of the underlying buffer. This commit includes extra tests for
these corner cases.
For example a GS8 format FrameBuffer with a width of 8, height of 2 and
stride of 10 should be able to fit into a buffer of size 18 (10 bytes for
the first horizontal line, and 8 bytes for the second -- the full 10 bytes
are not needed).
Similarly a 1 by 9 FrameBuffer in MONO_VLSB format with a stride of 10
should be able to fit into a buffer of length 11 (10 bytes for the first
8 lines, and then one byte for the 9th line.
Being able to do this is particularly important when cropping the corner of
an existing FrameBuffer, either to copy a sprite or to clip drawing.

This reverts commit c94a3205b0.
The idea behind this reverted commit was that it allowed to reconfigure the
UART to change only the baudrate, which is important in the context of a
PPP connection where the baudrate may be changed as part of the protocol.
Also, other ports like the rp2 port have this behaviour, where individual
parameters of the UART can be changed with the `.init()` method.
But this commit was no good for a few reasons:
1. It's a subtle breaking change to the UART API, because existing code
that constructs or initialises a UART with just the baudrate would
expect all other parameters to be reset to their defaults. But with
this commit those parameters would remain unchanged.
2. Constructing a UART like `UART(1, 9600)` also hits this code path of
only changing the baudrate and does not reset other parameters, which is
unexpected.
3. It doesn't support setting the baudrate via keyword, eg
`UART.init(baudrate=9600)`.
4. The `timeout_char` field is not updated when changing only the baudrate,
which can lead to unexpected timeouts when reading/writing.
Due to point (4), this commit broke the `tests/ports/stm32/uart.py` test,
the `uart.writechar(1)` has a timeout because the `uart.init(2400)` does
not set the `timeout_char` for the new baudrate.
Points (2)-(4) could be fixed, but point (1) (being a breaking change)
would remain as an issue. So the commit is reverted.

Prior to this commit, when flushing a UART on the rp2 port, it returns just
before the last character is sent out the wire.
Fix this by waiting until the BUSY flag is cleared.
This also fixes the behaviour of `UART.txdone()` to return `True` only when
the last byte has gone out.
Updated docs and tests to match. The test now checks that UART TX time is
very close to the expected time (prior, it was just testing that the TX
time was less than the expected time).
