* repo-add script - to add entries to a db file directly from package data (no PKGBUILD)

* libalpm api changes - move from a _getinfo(p, WHAT_WE_WANT) scheme to a
  typesafe _get_what_we_want(p) scheme [not 100% complete yet]
* some const correctness changes
* removal of PM_* types in alpm.h in favor of the pm*_t types used throughout
