Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
This caches the font list data to a file to minimize load times. Font
data will be refreshed when any font files are added/removed, based upon
a checksum of the font file names and dates (if available).
This uses fontconfig for looking up font files for freetype to use on
both linux and mac. It's apparently a bit more optimal and prevents us
from having to worry about the load time on the mac version as well.
Refactored and moved all the old code to the find-font-windows.c file,
as it's no longer used on anything but windows.
