Add support for checkers not related to code formatting to the
checkstyle.py script, and create a first checker that catches usage of
the LOG() macro without an explicit category.

clang-format produces better results than astyle as it can better match
the libcamera coding style. Default to clang-format over astyle, fall
back to astyle if clang-format isn't found, and add a --formatter
command line option to select a formatter manually.

As astyle doesn't strip trailing white spaces, strip them manually.
Organize the code to allow for new additional formatting steps if
needed.

In order to facilitate interpretation of diffs, highlight trailing white
space at end of lines with a red background.

The git diff command is invoked with relative paths, which causes git to
fail to locate files when the checkstyle.py script is run from
subdirectories of the git tree. Fix this by prepending the absolute path
to the git tree root directory to the file names.

checkstyle.py is a reimplementation of checkstyle.sh in Python, that
should be easier to extend with additional features.
Three additional features and enhancements are already implemented:
- While retaining the default behaviour of operating on the HEAD commit,
a list of commits can also be specified on the command line.
- Correct line numbers are printed in the diff output.
- The index and working tree are not touched, they can be dirty.
