Instead of raising a ZeroDivisionError, this tool now just skips any
elements in the DFU file that have zero size.

Updates the zephyr docker image to the latest, v0.11.13. This updates CI
to use zephyr SDK v0.12.2 and GCC v10.2.0 for the zephyr port.

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.

This allows customising which features can be enabled in a frozen library.
e.g. `include("path.py", extra_features=True)`
in path.py:
options.defaults(standard_features=True)
if options.standard_features:
# freeze standard modules.
if options.extra_features:
# freeze extra modules.

So that all MicroPython ports that use tinyusb use the same version. Also
requires fewer submodule checkouts when building rp2 along with other ports
that use tinyusb.

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PyPi package referred to is an out-of-date version of upip which is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
Python 2 (and pyserial for Python 2).

The -Og optimisation level produces a more realistic build, gives a better
debugging experience, and generates smaller code than -O0, allowing debug
builds to fit in flash.
This commit also assigns variables in can.c to prevent warnings when -Og is
used, and builds a board in CI with DEBUG=1 enabled.

This commit adds support to pyboard.py for the new raw REPL paste mode.
Note that this new pyboard.py is fully backwards compatible with old
devices (it detects if the device supports the new raw REPL paste mode).

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.

Updating to Black v20.8b1 there are two changes that affect the code in
this repository:
- If there is a trailing comma in a list (eg [], () or function call) then
that list is now written out with one line per element. So remove such
trailing commas where the list should stay on one line.
- Spaces at the start of """ doc strings are removed.

The existing implementation of mkdir() in this file is not sophisticated
enough to work correctly on all operating systems (eg Mac can raise
EISDIR). Using the standard os.makedirs() function handles all cases
correctly.

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
with their default values.

Formatting for `* sizeof` was fixed in uncrustify v0.71, so we no longer
need the fixups for it. Also, there was one file where the updated
uncrustify caught a problem that the regex didn't pick up, which is updated
in this commit.

This adds a new command line option `-v` to `tools/codeformat.py` to enable
verbose printing of all files that are scanned.
Normally `uncrustify` and `black` are called with the `-q` option so
setting verbose suppresses the `-q` option and on `black` also enables the
`-v` option which makes it print out all file names matching the filter
similar to how `uncrustify` does by default.
This suppresses the Parsing: <file> as language C lines. This makes
parsing run a bit faster and on CI it makes for less scrolling through logs
(and black already uses the -q option).
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.
