For some reason, parsing this does not seem to be intuitive to most
thirdparty consumers. For example, devtools uses grep and eval! And for
the longest time, it also did not support user makepkg.conf.
Other issues seen in the wild by makepkg.conf parsers include ignoring
~/.makepkg.conf, *only* using ~/.makepkg.conf, etc.
This is also sort of an uncomfortable amount of code to reimplement, so
I figured it could benefit from being split out into a utility library.
