Commit cb68a5741a broke automatic Python
feature detection when running tests, because some detection relied on a
crash of a feature script returning exactly b"CRASH".
This commit fixes this and improves the situation by testing for the lack
of a known pass result, rather than an exact failure result.

For an unconnected TCP socket, poll should return WR|HUP and read should
raise ENOTCONN. This is implemented by this commit and now the following
tests pass on esp32: extmod/usocket_tcp_basic.py,
net_hosted/connect_poll.py.

This change allows running the tests in tests/basics/ without any failures
(but some tests are still skipped).

This fixes `error: variable 'subpkg_tried' might be clobbered by 'longjmp'
or 'vfork' [-Werror=clobbered]` when compiling on ppc64le and aarch64 (and
possibly other architectures/toolchains).
This function includes the UART prescaler in the calculation (if it has
one, eg on H7 and WB MCUs).

This allows configuring the pre-allocated size of sys.modules dict, in
order to prevent unwanted reallocations at run-time (3 sys-modules is
really not quite enough for a larger project).
When building with STATIC undefined (e.g., -DSTATIC=), there are two
instances of mp_type_code that collide at link time: in profile.c and in
builtinevex.c. This patch resolves the collision by renaming one of them.
The STM32WB has a problem when address resolution is enabled: under certain
conditions the MCU can get into a state where it draws an additional 10mA
or so and eventually ends up with a broken BLE RX path in the silicon. A
simple way to reproduce this is to enable address resolution (which is the
default for NimBLE) and start the device advertising. If there is enough
BLE activity in the vicinity then the device will at some point enter the
bad state and, if left long enough, will have permanent BLE RX damage.
STMicroelectronics are aware of this issue. The only known workaround at
this stage is to not enable address resolution, which is implemented by
this commit.

Prior to this commit, if C2 was busy (eg lots of BLE activity) then it may
not have had time to respond to the notification on the IPCC_CH_MM channel
by the time additional memory was available to put on that buffer. In such
a case C1 would modify the free buffer list while C2 was potentially
accessing it, and this would eventually lead to lost memory buffers (or a
corrupt linked list). If all buffers become lost then ACL packets
(asynchronous events) can no longer be delivered from C2 to C1.
This commit fixes this issue by waiting for C2 to indicate that it has
finished using the free buffer list.

This change allows to build firmware for different rp2-based boards,
following how it is done in other ports like stm32 and esp32. So far only
the original Pico and Adafruit Feather RP2040 are added. Board names
should match (sans case) those in pico-sdk/src/boards/include/boards/.
Usage: Pico firmware can be build either using make as previously (it is
the default board) or by `make BOARD=PICO`. Feather is built by `make
BOARD=ADAFRUIT_FEATHER_RP2040`. Only the board name and flash drive size
is set, pin definition is taken from the appropriate pico-sdk board
definition. Firmware is saved in the directory build-BOARD_NAME.
Instantiation and init now support the rxbuf and txbuf keywords for setting
the buffer size. The default size is 256 bytes. The minimum and maximum
sizes are 32 and 32766 respectively.
uart.write() still includes checks for timeout, even if it is very unlikely
to happen due to a) lack of flow control support and b) the minimal timeout
values being longer than the time it needs to send a byte.
