Subject: makepkg: move option parsing code to separate file
This move the getopt replacement function parse_options out of
makepkg.sh.in and into a separate file. The code is inserted
into the relevant place in makepkg using m4.
This will allow the reuse of the option parsing code in other
scripts (i.e. pacman-key) while avoiding code duplication.
