While libcamera prefers usage of the C standard library headers (xxx.h)
over the C++ version (cxxx), we make an exception for cmath as the
overloaded versions of the math functions are convenient. Document this,
and adjust checkstyle.py accordingly.

This introduces a new argument "--amend" and a new special type of
commit "Amendment". It will check the style of changes that are in
the index combined with the changes of the last commit. So this is
the changes that would be applied by "git commit --amend" hence the
name of the argument.
This is needed to implement pre-commit hook.

This introduces a new command line "--staged" and a new special type of
commit "StagedChanges". It will check the style of changes that are in
the index, so the changes that would be committed by "git commit".
"--staged" was chosen to match with "git diff --staged" command line.
Other valid name could have been "--index" or "--cached". This was
my personal preference, aliases can be added later. Note that we must
not confuse this with working tree changes, as these changes are not
picked by "git commit".
This feature is needed to implement pre-commit hook.

This introduces a Commit class used in the final revlist list. All the
git commands are moved into that class. This class will be used to
introduce new types of commit (StagedChanges and Amendment) needed to implement
pre-commit hook support.

The tool has been renamed in 2016 to make it more obvious what it
is doing. There is no other changes needed on our side.

The checkstyle script expects hunks to be declared with a start line and
line count, however the unified diff format [0] declares that a single
line hunk will only have the start line:
> If a hunk contains just one line, only its start line number appears.
> Otherwise its line numbers look like ‘start,count’. An empty hunk is
> considered to start at the line that follows the hunk.
[0] https://www.gnu.org/software/diffutils/manual/html_node/Detailed-Unified.html#Detailed-Unified
Attempting to parse a single line hunk results in the following error:
File "./utils/checkstyle.py", line 110, in __init__
raise RuntimeError("Malformed diff hunk header '%s'" % line)
RuntimeError: Malformed diff hunk header '@@ -1 +1,2 @@
The DiffHunk class only makes use of the start line, and does not
utilise the line count, thus update the regex to make the unused
groups optional.

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.

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.
