The sys.stdin.buffer and sys.stdout.buffer streams work just as well (and
are just as fast) as pyb.USB_VCP on stm32 devices, so there's no need to
have the USB_VCP specialisation code, which just adds complexity.
Also, on stm32 devices with both USB and UART (or other serial interface),
if something other than the USB_VCP port is used for the serial connection
then mpremote mount will not work because it will default to reading and
writing on USB_VCP instead of the other connected serial stream.
As part of this simplification, support for a second port as input is
removed (this feature was never exposed to the user).

This implements (most of) the PEP-498 spec for f-strings and is based on
https://github.com/micropython/micropython/pull/4998 by @klardotsh.
It is implemented in the lexer as a syntax translation to `str.format`:
f"{a}" --> "{}".format(a)
It also supports:
f"{a=}" --> "a={}".format(a)
This is done by extracting the arguments into a temporary vstr buffer,
then after the string has been tokenized, the lexer input queue is saved
and the contents of the temporary vstr buffer are injected into the lexer
instead.
There are four main limitations:
- raw f-strings (`fr` or `rf` prefixes) are not supported and will raise
`SyntaxError: raw f-strings are not supported`.
- literal concatenation of f-strings with adjacent strings will fail
"{}" f"{a}" --> "{}{}".format(a) (str.format will incorrectly use
the braces from the non-f-string)
f"{a}" f"{a}" --> "{}".format(a) "{}".format(a) (cannot concatenate)
- PEP-498 requires the full parser to understand the interpolated
argument, however because this entirely runs in the lexer it cannot
resolve nested braces in expressions like
f"{'}'}"
- The !r, !s, and !a conversions are not supported.

The firmware for Teensy 4.0, Teensy 4.1 and MIMXRT1020_EVK are created.
Users of other MIMXRT10xx_EVK boards should be able to build the firmware
themselves, they might need specific DEBUG settings.
The Makefile had to be changed in order to build the .bin file as well.
Coverage calculated by Codecov has the same reliability/deterministic
issues as Coveralls did, so the problem is likely to do with the output of
lcov/gcov, rather than the analysis and display of the data.
Switch from lcov to gcov for data generation to try and simplify this
process of computing coverage.

Using just the list of available ports, instead of a hard-coded list of
possible ports, means that all ports will be available for auto connection.
And the order that they will be attempted in will match what's printed by
"mpremote connect list" (and will be the same as before, trying ACMx before
USBx). Auto-connect will also now work on Mac, and will allow all COM
ports on Windows.

This adds a coverage build and running of the test suite on a MIPS 32-bit
big endian architecture. It uses the feature of qemu to execute foreign
code as though it were native to the system (using qemu user mode). The
code compiled for MIPS will run under the qemu VM, but all syscalls made by
this code go to the host (Linux) system.

It's a bit of a pitfall with user C modules that including them in the
build does not automatically enable them. This commit changes the docs and
examples for user C modules to encourage writers of user C modules to
enable them unconditionally. This makes things simpler and covers most use
cases.

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 upip module is frozen into ports supporting it, and it is included in
the source tree, so there is no need to get it from PyPi. Moreover the
PyPi package referred to is an out-of-date version of upip which is
basically unrelated to our upip.py because the source is taken from a fork
of micropython-lib instead of this repository.
The main rules enforced are:
- At most 72 characters in the subject line, with a ": " in it.
- At most 75 characters per line in the body.
- No "noreply" email addresses.
Because the version included in xtensa-lx106-elf-standalone.tar.gz needs

The msvc compiler doesn't accept zero-sized arrays so let the freezing
process generate compatible C code in case no modules are found and the
involved arrays are all empty. This doesn't affect the functionality in
any way because those arrays only get accessed when mp_frozen_mpy_names
contains names, i.e. when modules are actually found.
MP_BC_CALL_FUNCTION will leave the result on the Python stack, so that
result must be discarded by MP_BC_POP_TOP.

Prior to this commit, pyboard.py used eval() to "parse" file data received
from the board. Using eval() on received data from a device is dangerous,
because a malicious device may inject arbitrary code execution on the PC
that is doing the operation.
Consider the following scenario:
Eve may write a malicious script to Bob's board in his absence. On return
Bob notices that something is wrong with the board, because it doesn't work
as expected anymore. He wants to read out boot.py (or any other file) to
see what is wrong. What he gets is a remote code execution on his PC.
Proof of concept:
Eve:
$ cat boot.py
_print = print
print = lambda *x, **y: _print("os.system('ls /; echo Pwned!')", end="\r\n\x04")
$ ./pyboard.py -f cp boot.py :
cp boot.py :boot.py
Bob:
$ ./pyboard.py -f cp :boot.py /tmp/foo
cp :boot.py /tmp/foo
bin chroot dev home lib32 media opt root sbin sys usr
boot config etc lib lib64 mnt proc run srv tmp var
Pwned!
There's also the possibility that the device is malfunctioning and sends
random and possibly dangerous data back to the PC, to be eval'd.
Fix this problem by using ast.literal_eval() to parse the received bytes,
instead of eval().

The file `mbedtls_errors/mp_mbedtls_errors.c` can be used instead of
`mbedtls/library/error.c` to give shorter error strings, reducing the build
size of the error strings from about 12-16kB down to about 2-5kB.
This reverts commit 4d6f60d428.
This implementation used the timeout as a maximum amount of time needed for
the operation, when actually the spec and other tools suggest that it's the
minumum delay needed between subsequent USB transfers.
This adds support for freezing an entire directory while keeping the
directory as part of the import path. For example
freeze("path/to/library", "module")
will recursively freeze all scripts in "path/to/library/module" and have
them importable as "from module import ...".

With only `sp_func_proto_paren = remove` set there are some cases where
uncrustify misses removing a space between the function name and the
opening '('. This sets all of the related options to `force` as well.
This is the result of running...
uncrustify -c tools/uncrustify.cfg --update-config-with-doc -o tools/uncrustify.cfg
...with some manual fixups to correct places where it changed things it
should not have.
Essentially it just adds new config parameters introduced in v0.71.0
