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.

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).

This adds the Python files in the tests/ directory to be formatted with
./tools/codeformat.py. The basics/ subdirectory is excluded for now so we
aren't changing too much at once.
In a few places `# fmt: off`/`# fmt: on` was used where the code had
special formatting for readability or where the test was actually testing
the specific formatting.

This eliminates the need for the sizeof regex fixup by rearranging things a
bit. All other bitfields already use the parentheses around expressions
with sizeof, so one case is fixed by following this convention.
VM_MAX_STATE_ON_STACK is the only remaining problem and it can be worked
around by changing the order of the operands.

This commit adds a tool, codeformat.py, which will reformat C and Python
code to fit a certain style. By default the tool will reformat (almost)
all the original (ie not 3rd-party) .c, .h and .py files in this
repository. Passing filenames on the command-line to codeformat.py will
reformat only those. Reformatting is done in-place.
uncrustify is used for C reformatting, which is available for many
platforms and can be easily built from source, see
https://github.com/uncrustify/uncrustify. The configuration for uncrustify
is also added in this commit and values are chosen to best match the
existing code style. A small post-processing stage on .c and .h files is
done by codeformat.py (after running uncrustify) to fix up some minor
items:
- space inserted after * when used as multiplication with sizeof
- #if/ifdef/ifndef/elif/else/endif are dedented by one level when they are
configuring if-blocks and case-blocks.
For Python code, the formatter used is black, which can be pip-installed;
see https://github.com/psf/black. The defaults are used, except for line-
length which is set at 99 characters to match the "about 100" line-length
limit used in C code.
The formatting tools used and their configuration were chosen to strike a
balance between keeping existing style and not changing too many lines of
code, and enforcing a relatively strict style (especially for Python code).
This should help to keep the code consistent across everything, and reduce
cognitive load when writing new code to match the style.
