most of the former options in makepkg.conf, and are described in detail
there:
BUILDENV=(fakeroot !distcc color !ccache)
OPTIONS=(strip !docs !libtool emptydirs)
Note that PKGBUILD specified options will always have final say. They will
now be specified as they are above, except using lowercase 'options' array.
* makepkg was fixed so options actually work as expected.
* renamed pmlist_t -> alpm_list_t
* made alpm_list_t a public type (alpm_list.h header)
* removed additional storage for registered DBs in pacman source
* some code cleanup
* removed duplicate (pm)list_display functions from pacman source
* misc code cleanup
