Previously parseopts checked if there was an argument by checking
that the string was non-empty, resulting in empty arguments being
incorrectly considered non-existent. This change makes parseopts check
if arguments exist at all, rather than checking that they are non-empty

Adds a "?" suffix that can be used to indicate that an option's argument is
optional.
This allows options to have a default behaviour when the user doesn't
specify one, e.g.: --color=[when] being able to behave like --color=auto
when only --color is passed
Options with optional arguments given on the command line will be returned
in the form "--opt=optarg" and "-o=optarg". Despite that not being the
syntax for passing an argument with a shortopt (trying to pass -o=foo
would make -o's argument "=foo"), this is done to allow the caller to split
the option and its optarg easily

parseopts is used in makepkg and other scripts such as pacman-key as a
getopt replacement.
Instead of including it in those scripts via a macro, move it to
libmakepkg/util/parseopts.sh and have scripts source this file where
appropriate.
To keep the parseopts test, a new variable was introduced:
PM_LIBMAKEPKG_DIR
