This provides a significant performance boost for qstr_find_strn, which is
called a lot during parsing and loading of .mpy files, as well as interning
of string objects (which happens in most string methods that return new
strings).
Also adds comments to explain the "static" qstrs. These are part of the
.mpy ABI and avoid needing to duplicate string data for QSTRs known to
already be in the firmware. The static pool isn't currently sorted, but in
the future we could either split the static pool into the sorted regions,
or in the next .mpy version just sort them.
Based on initial work done by @amirgon in #6896.

Required by upcoming qstr sorting.

This test depends on the order in which qstrs are stored in ROM, which
affects the order in which `dir()` will probe the object to see what it
supports. Because of the lazy-loading in asyncio/__init__.py, if it
tries to do e.g. `wait_for_ms` before `funcs` then it will import funcs,
making `funcs` later succeed. But in the other way around, `funcs` will
initially not be found.

These tests are designed to measure changes in performance relating to:
- string interning / searching for existing strings
- map lookup
- string operations
- string hashing

The flags returned from `select()` were misinterpreted to mean an error had
occurred for the socket, when it's actually just an exceptional condition
for the socket, such as OOB data.

This is just scaffolding for now, but the idea is that there should be an
addition to this file for every commit that uses the
`MICROPY_PREVIEW_VERSION_2` macro.

This provides a way to enable features and changes slated for MicroPython
2.x, by running `make MICROPY_PREVIEW_VERSION_2=1`. Also supported for
the cmake ports (except Zephyr).
This is an alternative to having a 2.x development branch (or equivalently,
keeping a 1.x release branch). Any feature or change that needs to be
"hidden" until 2.x can use this flag (either in the Makefile or the
preprocessor).
A good example is changing function arguments or other public API features,
in particular to aid in improving consistency between ports.
When `MICROPY_PREVIEW_VERSION_2` is enabled, the REPL banner is amended to
say "MicroPython (with v2.0 preview) vX.Y.Z", and sys.implementation gets a
new field `_v2` set to `True`.

else.
Also move declarations of machine_pin_type and machine_rtc_type to the

This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings. For all ports except the two listed
below there is no functional change.
The nrf port has UART.sendbreak() removed, but this method previously did
nothing.
The zephyr port has the following methods added:
- UART.init(): supports setting timeout and timeout_char.
- UART.deinit(): does nothing, just returns None.
- UART.flush(): raises OSError(EINVAL) because it's not implemented.
- UART.any() and UART.txdone(): raise NotImplementedError.

This commit makes it so that MICROPY_PY_MACHINE_PWM is enabled if at least
one of MICROPY_PY_MACHINE_HW_PWM and/or MICROPY_PY_MACHINE_SOFT_PWM are
enabled. This simplifies the configuration for boards, and fixes DVK_BL652
which enabled PWM without selecting software or hardware implementations.
With this change, DVK_BL652 and EVK_NINA_B1 now enable (hardware) PWM.

This factors the basic top-level I2S class code from the ports into
extmod/machine_i2s.c:
- I2S class definition and method table.
- The init and deinit method wrappers.
- The make_new code.
Further factoring will follow.

With public declarations moved to extmod/modmachine.h. It's now mandatory
for a port to define MICROPY_PY_MACHINE_PWM_INCLUDEFILE if it enables
MICROPY_PY_MACHINE_PWM. This follows how extmod/machine_wdt.c works.
All ports have been updated to work with this modified scheme.

There are currently 7 ports that implement machine.WDT and a lot of code is
duplicated across these implementations. This commit factors the common
parts of all these implementations to a single location in
extmod/machine_wdt.c. This common code provides the top-level Python
bindings (class and method wrappers), and then each port implements the
back end specific to that port.
With this refactor the ports remain functionally the same except for:
- The esp8266 WDT constructor now takes keyword arguments, and accepts the
"timeout" argument but raises an exception if it's not the default value
(this port doesn't support changing the timeout).
- The mimxrt and samd ports now interpret the argument to WDT.timeout_ms()
as signed and if it's negative truncate it to the minimum timeout (rather
than it being unsigned and a negative value truncating to the maximum
timeout).

The unwritten API contract expected of a VFS.getcwd() by mp_vfs_getcwd()
is that its return value should be either "" or "/" when the CWD is at
the root of the VFS and otherwise start with a slash and not end with a
slash. This was not correctly implemented in VfsPosix for instances with
a non-empty root - the required leading slash, if any, was cut off
because the root length includes a trailing slash. This would result in
missing slashes in the middle of the return value of os.getcwd() or in
uninitialized garbage from beyond a string's null terminator when the
CWD was at the VFS root.

The unwritten API contract expected of a VFS by mp_vfs_lookup_path() is
that paths passed in are relative to the root of the VFS if they start
with '/' and relative to the current directory of the VFS otherwise.
This was not correctly implemented in VfsPosix for instances with a
non-empty root - all paths were interpreted relative to the root. Fix
that. Since VfsPosix tracks its CWD using the "external" CWD of the Unix
process, the correct handling for relative paths is to pass them through
unmodified.
Also, when concatenating absolute paths, fix an off-by-one resulting in
a harmless double slash (the root path already has a trailing slash).

These tests test an unrealistic situation and only pass by accident due
to a bug. The upcoming fix for the bug would make them fail.
The unrealistic situation is that VfsPosix methods are called with
relative paths while the current working directory is somewhere outside
of the root of the VFS. In the intended use of VFS objects via
os.mount() (as opposed to calling methods directly as the tests do),
this never happens, as mp_vfs_lookup_path() directs incoming calls to
the VFS that contains the CWD.
Make the testing situation realistic by changing the working directory
to the root of the VFS before calling methods on it, as the subsequent
relative path accesses expect.
Thanks to the preceding commit, the tests still pass, but still for the
wrong reason. The following commit "Fix relative paths on non-root VFS"
will make them pass for the correct reason.

A VfsPosix created with a relative root path would get confused when
chdir() was called on it and become unable to properly resolve absolute
paths, because changing directories effectively shifted its root. The
simplest fix for that would be to say "don't do that", but since the
unit tests themselves do it, fix it by making a relative path absolute
before storing it.

This commit implements Ethernet support for STM32H5. Changes are:
- Add Cortex-M33 MPU code. Ethernet driver requires MPU to define cache
strategy for DMA buffers (descriptors and frames).
- Add support for STM32H5 Ethernet controller. The controller is mostly
compatible with the STM32H7. However the descriptor layout is different.
- Adapt clocking and reset for STM32H5.
Tested on NUCLEO-H563ZI and STM32H573I-DK, using ping and iperf3. TCP
rates of 80-90 Mbits/sec were achievable.
