From: Jakob Gruber <jakob.gruber at gmail.com>
In the following, the letters SRUDQ refer to the corresponding pacman
operations.
Most of the work in this commit is about removing as many options as
possible from the global section and moving them to where they actually
belong.
Additionally, --ignore{,group} are added to U and --dbonly is added
to S.
--dbonly added to S
--asdeps moved to S/U/D
--asexplicit moved to S/U/D
--print-format moved to S/U/R
--noprogressbar moved to S/U/R
--noscriptlet moved to S/U/R
--ignorepkg added to U
--ignoregrp added to U
-d moved to S/U/R (--nodeps) and Q (--deps)
-p moved to S/U/R (--print) and Q (--file)
-f moved to S/U
