Prior to this commit, on Pico W (where the CYW43 driver is enabled) the PIO
instruction memory was not released on soft reset, so using PIO after a
soft reset would eventually (after a few soft resets) lead to ENOMEM when
allocating a PIO program.
This commit fixes that by tracking the use of PIO memory by this module and
freeing it on soft reset.
Similarly, use of the state machines themselves are tracked and released on
soft reset.
Fixes issue #9003.

Make this more generally useful and in line with what the mingw
and unix ports do: 16bit dig size to work on 32bit ports, a
self-contained qstrdefs.preprocessed.h because makemanifest.py
uses that, and a dev variant which effectively puts this to use:
previously the uasyncio module wasn't frozen but instead tests
ran by importing it from the extmod/ directory.
Code in tools/mpy-tool.py and py/frozenmod.c relies on the source file
path encoded in a .mpy file to have forward slashes (e.g. by searching
for '/__init__.py'). Enforce that when creating these files, thereby
fixing import of .mpy files and frozen modules not working before
because they could have backslashes when built with the windows port.
The mpversion.h file must exist before py/ source can be preprocessed,
but this went unnoticed because micropython.vcxproj always calls
MakeVersionHdr before MakeQstrDefs.
The variant.props may have incompatible build options which break
the mpy-cross build and in any case mpy-cross has nothing to do
with variant support.
This is in line with the change made for other ports in d53c3b6a: since
the default output directory already includes the variant name in it
there's no need to add it to the executable as well.
This will ensure that any board with networking support gets:
- webrepl
- mip
- urequests
- ntptime

This drops the `.cpu` directive from the ARM gchelper_*.s files. Having
this directive breaks the linker when targeting older CPUs (e.g. `-mthumb
-mthumb-interwork` for `-mcpu=arm7tdmi`). The actual target CPU should be
determined by the compiler options.
The exact CPU doesn't actually matter, but rather the supported assembly
instruction set. So the files are renamed to *_thumb1.s and *thumb2.s to
indicate the instruction set support instead of the CPU support.

Prior to this commit, Pin(Pin.OPEN_DRAIN, value=0) would not set the
initial value of the open-drain pin to low, instead it would be high.

The mp_plat_print output is already being used by the subsequent call to
mp_obj_print_exception(). And this eliminates all references to printf for
this port (at least in non-debug builds).

Unless MICROPY_OBJ_REPR == MICROPY_OBJ_REPR_D, these macros only work with
values and "->"/"." expressions as their sole argument. In other words,
the macros are broken with expressions which contain operations of lower
precedence than the cast operator.
Depending on situation, the old code either results in compiler error:
MP_OBJ_TO_PTR(flag ? o1 : o2) expands into "(void *)flag ? o1 : o2",
which some compiler configurations will reject (e.g. GCC -Wint-conversion
-Wint-to-pointer-cast -Werror)
Or in an incorrect address calculation:
For ptr declared as "uint8_t *" the MP_OBJ_FROM_PTR(ptr + off)
expands into ((mp_obj_t)ptr) + off, resulting in an obviously
wrong address.

This is important for literal tuples, e.g.
f"{a,b,}, {c}" --> "{}".format((a,b), (c),)
which would otherwise result in either a syntax error or the wrong result.

32-bit platforms only support a slice offset start of 24 bit max due to the
limited size of the mp_obj_array_t.free member. Similarly on 64-bit
platforms the limit is 56 bits.
This commit adds an OverflowError if the user attempts to slice a
memoryview beyond this limit.

The delay is 1 ms. It avoids the crashes reported by the
issues #8289, #8792 and #9236 with esp-idf versions >= 4.2, but does
not solve an underlying problem in the esp-idf.
The major setting is about the PHY interface configuration. The
configuration matches the Olimex ESP32 Gateway as well.
Tested with esp-idf v4.2.4 and Olimex ESP32 POE boards.
pre-commit manages its own dependencies otherwise (including Black), but
this one is a C/C++ binary so needs to be installed independently.

`esp_eth_ioctl(ETH_CMD_S_MAC_ADDR)` sets the MAC address of the hardware
device, but we also need to notify the upper layers of the change so that
e.g. DHCP work properly.
Add support for various SPI-based ethernet chips (W5500, KSZ8851SNL,
DM9051) to the ESP32 port. This leverages the existing support in ESP-IDF
for these chips -- which configures these chips in "MAC raw" mode -- and
the existing support for network.LAN in the ESP32 port. In particular,
this doesn't leverage the wiznet5k support that is used on the rp2 and
stm32 ports (because that's for native use of lwIP).
Tested on the POE Featherwing (with the SJIRQ solder jumper bridged) and a
ESP32-S3 feather.
A note about the interrupt pin: The W5500 implementation within ESP-IDF
relies on hardware interrupt, and requires the interrupt pin from the W5500
to be wired to a GPIO. This is not the case by default on the Adafruit
Ethernet FeatherWing, which makes it not directly compatible with this
implementation.
Both the direction and the Pin used for ref_clk can now be configured. It
Requires at least idf v4.4. The new keyword arguments to the constructor
are:
- ref_clk_mode=mode: with mode being Pin.IN or Pin.OUT. If it is not set,
then the default configuration is used, which may be configured by
kconfig settings.
- ref_clk=pin_obj: which defines the Pin used for ref_clk. This is either
Pin(0), Pin(16) or Pin(17). No check is done for the pin number. If it
is the wrong one, it simply will not work. Besides that, no harm.
LAN8710 uses the same drivers as LAN8720, so this commit just adds the
names. Alternatively, both could be summarised under LAN87xx, like the
esp-idf does.
