Currently "src/" mostly contains the source code of the daemon.
I say mostly, because that is not true, there are also the device,
settings, wwan, ppp plugins, the initrd generator, the pppd and dhcp
helper, and probably more.
Also we have source code under libnm-core/, libnm/, clients/, and
shared/ directories. That is all confusing.
We should have one "src" directory, that contains subdirectories. Those
subdirectories should contain individual parts (libraries or
applications), that possibly have dependencies on other subdirectories.
There should be a flat hierarchy of directories under src/, which
contains individual modules.
As the name "src/" is already taken, that prevents any sensible
restructuring of the code.
As a first step, move "src/" to "src/core/". This gives space to
reorganize the code better by moving individual components into "src/".
For inspiration, look at systemd's "src/" directory.

- accept directory names in the command line. In that case,
still honor the excluded files. That is a major improvement
for me, because I usually only want to reformat a directory
that I know has changed and it is fast to only process some
directories.
- pass all files at once to clang-format. For me that gives
a significant speed improvement (about 3 times faster), although
clang-format is only single threaded. Possibly clang-format could
even be faster by checking files in parallel.
In case of a style error, the script still falls back to
iterate over all files to find the first bad file and print
the full diff. But that is considered an unusual case.
- make it correctly work from calling it from a subdirectory.
In that case, we only check files inside that directory --
but still correctly honor the excluded files.
"shared/nm-std-aux/unaligned.h" is taken from systemd and frequently
re-imported via the "systemd" branch.
It is not our code, and should not be formatted with our clang-format.
