codeformat: Fix filename matching In #4683, tannewt noticed that uncrustify was not running on some file in common-hal. I investigated and found that it was not being run on a bunch of paths. Rather than make incremental changes, I rewrote list_files to work bsaed on regular expressions; these regular expressions are created from the same git-style glob patterns. I spot-checked some specific filenames after this change, and all looks good: ``` $ python3 tools/codeformat.py -v --dry-run tests/basics/int_small.py ports/raspberrypi/common-hal/pulseio/PulseIn.c extmod/virtpin.c tests/thread/thread_exit1.py ports/raspberrypi/background.h extmod/re1.5/recursiveloop.c tools/codeformat.py -v --dry-run tests/basics/int_small.py ports/raspberrypi/common-hal/pulseio/PulseIn.c extmod/virtpin.c tests/thread/thread_exit1.py ports/raspberrypi/background.h extmod/re1.5/recursiveloop.c uncrustify -c /home/jepler/src/circuitpython/tools/uncrustify.cfg -lC --no-backup extmod/virtpin.c ports/raspberrypi/background.h ports/raspberrypi/common-hal/pulseio/PulseIn.c black --fast --line-length=99 -v tests/thread/thread_exit1.py ``` recursiveloop and int_small are excluded, while PulseIn, virtpin, and background are included.
