To keep things neat and tidy, we ensure that each file has 1 and only 1
newline at the end of each file.

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.

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.
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.
