If a board defines USBD_VID then that will be used instead of the default.
And then the board must also define all USBD_PID_xxx values that it needs.

The following simple usocket example throws an error EINVAL on connect
import usocket
s = usocket.socket()
s.connect(usocket.getaddrinfo('www.micropython.org', 80)[0][-1])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 22] EINVAL
Fixing the context parameter in calls of net_context_get_family() and
net_context_get_type(), the connect works fine.
Tested on a nucleo_h743zi board.
Refactors the zephyr build infrastructure to build MicroPython as a
cmake target, using the recently introduced core cmake rules.
This change makes it possible to build the zephyr port like most other
zephyr applications using west or cmake directly. It simplifies building
with extra cmake arguments, such as specifying an alternate conf file or
adding an Arduino shield. It also enables building the zephyr port
anywhere in the host file system, which will allow regressing across
multiple boards with the zephyr twister script.

The underlying OS (the ESP-IDF) uses it's own internal errno codes and so
it's simpler and cleaner to use those rather than trying to convert
everything to the values defined in py/mperrno.h.
It's now replaced by cmake/idf.py. But a convenience Makefile is still
provided with traditional targets like "all" and "deploy".

This commit adds support for building the esp32 port with cmake, and in
particular it builds MicroPython as a component within the ESP-IDF. Using
cmake and the ESP-IDF build infrastructure makes it much easier to maintain
the port, especially with the various new ESP32 MCUs and their required
toolchains.

This allows changing the baudrate of the UART without reinitialising it
(reinitialising can lead to spurious characters sent on the TX line).

On i.MX the SysTick IRQ cannot wake the CPU from a WFI so the CPU was
blocked on WFI waiting for USB data in mp_hal_stdin_rx_chr() even though it
had already arrived (because it may arrive just after calling the check
tud_cdc_available()). This commit fixes this problem by using SEV/WFE to
indicate that there has been a USB event.
The mp_hal_stdout_tx_strn() function is also fixed so that it doesn't
overflow the USB buffers.

outside the source tree, and the py/modarray.c file will still be found.

The "word" referred to by BYTES_PER_WORD is actually the size of mp_obj_t
which is not always the same as the size of a pointer on the target
architecture. So rename this config value to better reflect what it
measures, and also prefix it with MP_.
For uses of BYTES_PER_WORD in setting the stack limit this has been
changed to sizeof(void *), because the stack usually grows with
machine-word sized values (eg an nlr_buf_t has many machine words in it).

Default to just calling python since that is most commonly available: the
official installer or zipfiles from python.org, anaconda, nupkg all result
in python being available but not python3. In other words: the default
used so far is wrong. Note that os.name is 'posix' when running the python
version which comes with Cygwin or MSys2 so they are not affected by this.
However of all possible ways to get Python on Windows, only Cygwin provides
no python command so update the default way for running tests in the
README.
With mboot encrpytion and fsload enabled, the DEBUG build -O0 compiler
settings result in mboot no longer fitting in the 32k sector. This commit
changes this to -Og which also brings it into line with the regular stm32
build.
MCUs with device-only USB peripherals (eg L0, WB) do not implement (at
least not in the ST HAL) the HAL_PCD_DisconnectCallback event. So if a USB
cable is disconnected the USB driver does not deinitialise itself
(usbd_cdc_deinit is not called) and the CDC driver can stay in the
USBD_CDC_CONNECT_STATE_CONNECTED state. Then if the USB was attached to
the REPL, output can become very slow waiting in usbd_cdc_tx_always for
500ms for each character.
The disconnect event is not implemented on these MCUs but the suspend event
is. And in the situation where the USB cable is disconnected the suspend
event is raised because SOF packets are no longer received.
The issue of very slow output on these MCUs is fixed in this commit (really
worked around) by adding a check in usbd_cdc_tx_always to see if the USB
device state is suspended, and, if so, breaking out of the 500ms wait loop.
This should also help all MCUs for a real USB suspend.
A proper fix for MCUs with device-only USB would be to implement or somehow
synthesise the HAL_PCD_DisconnectCallback event.
See issue #6672.

PIO state machines can make a conditional jump on the state of a pin: the
`JMP PIN` command. This requires the pin to be configured with
`sm_config_set_jmp_pin`, but until now we didn't have a way of doing that
in MicroPython.
This commit adds a new `jmp_pin=None` argument to `StateMachine`. If it is
not `None` then we try to interpret it as a Pin, and pass its value to
`sm_config_set_jmp_pin`.
