This new machine-module driver provides a "USBDevice" singleton object and
a shim TinyUSB "runtime" driver that delegates the descriptors and all of
the TinyUSB callbacks to Python functions. This allows writing arbitrary
USB devices in pure Python. It's also possible to have a base built-in
USB device implemented in C (eg CDC, or CDC+MSC) and a Python USB device
added on top of that.

Prior to this commit, the pin defined for power would be used by the
esp_idf driver to reset the PHY. That worked, but sometimes the MDIO
configuration started before the power was fully settled, leading to an
error.
With the change in this commit, the power for the PHY is independently
enabled in network_lan.c with a 100ms delay to allow the power to settle.
A separate define for a reset pin is provided, even if the PHY reset
pin is rarely connected.
Fixes issue #14013.

The STATIC macro was introduced a very long time ago in commit
d5df6cd44a. The original reason for this was
to have the option to define it to nothing so that all static functions
become global functions and therefore visible to certain debug tools, so
one could do function size comparison and other things.
This STATIC feature is rarely (if ever) used. And with the use of LTO and
heavy inline optimisation, analysing the size of individual functions when
they are not static is not a good representation of the size of code when
fully optimised.
So the macro does not have much use and it's simpler to just remove it.
Then you know exactly what it's doing. For example, newcomers don't have
to learn what the STATIC macro is and why it exists. Reading the code is
also less "loud" with a lowercase static.
One other minor point in favour of removing it, is that it stops bugs with
`STATIC inline`, which should always be `static inline`.
Methodology for this commit was:
1) git ls-files | egrep '\.[ch]$' | \
xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/"
2) Do some manual cleanup in the diff by searching for the word STATIC in
comments and changing those back.
3) "git-grep STATIC docs/", manually fixed those cases.
4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

Allows bytecode itself to be used instead of an mp_raw_code_t in the simple
and common cases of a bytecode function without any children.
This can be used to further reduce frozen code size, and has the potential
to optimise other areas like importing.

Greedily grab as much RMT memory as we can. It blocks other RMT
transmit channels but we only use it temporarily anyway. The more
we can grab, the fewer interrupts are needed to keep the transmit
going.
Flickers may still happen due to file system writes but most of the
time the animation just pauses.
On ESP32, move CircuitPython to the second core. This helps NeoPixel
by moving the RMT interrupt to the second core as well.
When testing ESP32 I noticed that settings.toml writes won't apply
until after hard reset. This removes that constraint but still
requires the password to enable the web workflow.
Fixes#3835
This commit changes how library packages are searched for when a manifest
file is loaded: there is now simply a list of library paths that is
searched in order for the given package. This list defaults to the
main directories in micropython-lib, but can be added to -- either appended
or prepended -- by using `add_library()`.
In particular the way unix-ffi library packages are searched has changed,
because the `unix_ffi` argument to `require()` is now removed. Instead, if
a build wants to include packages from micropython-lib/unix-ffi, then it
must explicitly add this to the list of paths to search using:
add_library("unix-ffi", "$(MPY_LIB_DIR)/unix-ffi")

If you have a variable frequency and pulse width, and you want to optimize
pulse resolution, then you must do a calculation beforehand to ensure you
normalize the array to keep all list values within bound. That calculation
requires RMT.source_freq(), RMT.clock_div(), and this 32767 constant.
Signed-off-by: Mark Blakeney <mark.blakeney@bullet-systems.net>
To create an esp32.RMT() instance with an optimum (i.e. highest resolution)
clock_div is currently awkward because you need to know the source clock
frequency to calculate the best clock_div, but unfortunately that is only
currently available as an source_freq() method on the instance after you
have already created it. So RMT.source_freq() should really be a class
method, not an instance method. This change is backwards compatible for
existing code because you can still reference that function from an
instance, or now also, from the class.

This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings. At this stage only esp32 implements
this class, so the code for the bindings comes from that port.

See https://github.com/micropython/micropython/issues/12127 for details.
Previously at the point when a release is made, we update mpconfig.h
and set a git tag. i.e. the version increments at the release.
Now the version increments immediately after the release. The workflow is:
1. Final commit in the cycle updates mpconfig.h to set (X, Y, 0, 0) (i.e.
clear the pre-release state).
2. This commit is tagged "vX.Y.0".
3. First commit for the new cycle updates mpconfig.h to set (X, Y+1, 0, 1)
(i.e. increment the minor version, set the pre-release state).
4. This commit is tagged "vX.Y+1.0-preview".
The idea is that a nightly build is actually a "preview" of the _next_
release. i.e. any documentation describing the current release may not
actually match the nightly build. So we use "preview" as our semver
pre-release identifier.
Changes in this commit:
- Add MICROPY_VERSION_PRERELEASE to mpconfig.h to allow indicating that
this is not a release version.
- Remove unused MICROPY_VERSION integer.
- Append "-preview" to MICROPY_VERSION_STRING when the pre-release state
is set.
- Update py/makeversionhdr.py to no longer generate MICROPY_GIT_HASH.
- Remove the one place MICROPY_GIT_HASH was used (it can use
MICROPY_GIT_TAG instead).
- Update py/makeversionhdr.py to also understand
MICROPY_VERSION_PRERELEASE in mpconfig.h.
- Update py/makeversionhdr.py to convert the git-describe output into
semver-compatible "X.Y.Z-preview.N.gHASH".
- Update autobuild.sh to generate filenames using the new scheme.
- Update remove_old_firmware.py to match new scheme.
- Update mpremote's pyproject.toml to handle the "-preview" suffix in the
tag. setuptools_scm maps to this "rc0" to match PEP440.
- Fix docs heading where it incorrectly said "vvX.Y.Z" for release docs.

This changes from the previous limit of 15 characters. Although DHCP and
mDNS allow for up to 63, ESP32 and ESP8266 only allow 32, so this seems
like a reasonable limit to enforce across all ports (and avoids wasting the
additional memory).
Also clarifies that `MICROPY_PY_NETWORK_HOSTNAME_MAX_LEN` does not include
the null terminator (which was unclear before).

The primary purpose of this commit is to make decompress default to
wbits=15 when the format is gzip (or auto format with gzip detected). The
idea is that someone decompressing a gzip stream should be able to use the
default `deflate.DeflateIO(f)` and it will "just work" for any input
stream, even though it uses a lot of memory.
This is done by making uzlib report gzip files as having wbits set to 15
in their header (where it previously only set the wbits out parameter for
zlib files), and then fixing up the logic in `deflateio_init_read`.
Updates the documentation to match.
