libmetal source files already have the build directory prefix, because
they're auto-generated inside the build directory. When they're added
to `SRC_THIRDPARTY_C`, another build directory prefix is added resulting
in the object files being generated in a nested build directory.
This patch strips the build directory prefix before adding libmetal's
source files.

This commit adds code to distinguish between regular Linux and Android,
also adding a specific entry for the platform libc. The reported libc

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.

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 f4ab9d924790581989f2398fe30bbac5d680577f 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`.

This allows the stream to be set to `None`, which essentially stops all PPP
communication without disconnecting the session.
This allows replacing the stream on-the-fly to suspend it, for example to
send AT commands to a modem without completely disconnecting and
re-establishing the PPP connection:
uart = ppp.config('stream')
ppp.config(stream=None)
uart.write(b'+++')
# do some AT commands
uart.write(b'ATO\r\n')
ppp.config(stream=uart)
Any attempted communication by PPP while the stream is not connected will
register as simple packet loss to the LwIP stack because we return 0 for
any write calls, and protocols like TCP will then automatically handle
retrying.

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().

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.

In MSVC debug builds with debug error reporting set to showing a dialog (to
allow attaching the debugger), any application which imports the logging
module and leaves the default handlers would result in this dialog because
logging.shutdown is called at exit and that flushes the default handler
which has stderr as its stream.
This commit fixes that by not fsync'ing stdin/out/err.
Also adds a comment related to checking whether a file is stdin/out/err,
which is difficult to fix properly.

This commit adds a new `network.PPP` interface which works on any port that
has bare-metal lwIP, eg rp2, stm32, mimxrt.
It has been tested on stm32. A board needs to enable
`MICROPY_PY_NETWORK_PPP_LWIP` and then it can use it as follows:
import network
ppp = network.PPP(uart)
ppp.connect()
while not ppp.isconnected():
pass
# use `socket` module as usual, etc
ppp.disconnect()
Usually the application must first configure the cellular/etc UART link to
get it connected and in to PPP mode first (eg ATD*99#), before handing over
control to `network.PPP`.
The PPP interface automatically configures the UART IRQ callback to call
PPP.poll() on incoming data.

Currently the stack limit margin is hard-coded in each port's call to
`mp_stack_set_limit()`, but on threaded ports it's fiddlier and can lead to
bugs (such as incorrect thread stack margin on esp32).
This commit provides a new API to initialise the C Stack in one function
call, with a config macro to set the margin. Where possible the new call
is inlined to reduce code size in thread-free ports.
Intended replacement for `MP_TASK_STACK_LIMIT_MARGIN` on esp32.
The previous `stackctrl.h` API is still present and unmodified apart from a
deprecation comment. However it's not available when the
`MICROPY_PREVIEW_VERSION_2` macro is set.

`mbedtls_pk_parse_key()` expects `key_len` to include the NULL terminator
for PEM data but not for DER encoded data. This also applies to
`mbedtls_x509_crt_parse()` and `cert_len`.
Since all PEM data contains "-----BEGIN" this is used to check if the data
is PEM (as per mbedtls code).
This can be done for both v2 and v3 of mbedtls since the fundamental
behaviour/expectation did not change. What changed is that in v3 the
PKCS#8 DER parser now checks that the passed key buffer is fully utilized
and no bytes are remaining (all other DER formats still do not check this).

It does the same thing, raising `SystemExit`.
Signed-off-by: Damien George <damien@micropython.org>

The current situation with SystemExit and soft reset is the following:
- `sys.exit()` follows CPython and just raises `SystemExit`.
- On the unix port, raising `SystemExit` quits the application/MicroPython,
whether at the REPL or in code (this follows CPython behaviour).
- On bare-metal ports, raising `SystemExit` at the REPL does nothing,
raising it in code will stop the code and drop into the REPL.
- `machine.soft_reset()` raises `SystemExit` but with a special flag set,
and bare-metal targets check this flag when it propagates to the
top-level and do a soft reset when they receive it.
The original idea here was that a bare-metal target can't "quit" like the
unix port can, and so dropping to the REPL was considered the same as
"quit". But this bare-metal behaviour is arguably inconsistent with unix,
and "quit" should mean terminate everything, including REPL access.
This commit changes the behaviour to the following, which is more
consistent:
- Raising `SystemExit` on a bare-metal port will do a soft reset (unless
the exception is caught by the application).
- `machine.soft_reset()` is now equivalent to `sys.exit()`.
- unix port behaviour remains unchanged.
Tested running the test suite on an stm32 board and everything still
passes, in particular tests that skip by raising `SystemExit` still
correctly skip.

Being able to send data out in LSB format can be useful, and having support
in the low-level driver is much better than requiring Python code to
reorder the bits before sending them / after receiving them. In particular
if the hardware does not support the LSB format (eg RP2040) then one needs
to use the SoftSPI in LSB mode.
For this change a default definition of `MICROPY_PY_MACHINE_SPI_MSB/_LSB`
was added to `py/mpconfig.h`, making them available to all ports. The
identical defines in `esp32/mpconfigport.h` were deleted.
Resolves issues #5340, #11404.

good coverage of those top 500 domains.
