pacman/lib/libalpm/db.h
Aaron Griffin 7f5dada885 Big commit this time:
* Moved entirely to alpm_pkg_get_* accessors, to read data on demand
* Mostly removed the INFRQ_ parameters from outside the be_files backend (making
  the backend more extensible in the long run)
* packages created from _alpm_db_scan now have the db and origin set (making
  accessors actually work for these packages)
* removed _alpm_db_ensure_pkgcache

* totally revamped the _alpm_checkconflicts function, making it cleaner and
  easier to read (and thus fix in the long run) - maintainable code ftw
  NOTE: feel free to rename the functions... I couldn't think of anything better

* removed an extra loop in sync.c:find_replacements - no sense in looping over
  an entire DB while strcmp'ing the name, when we have get_pkgfromcache

Other:
* package struct "license" -> "licenses"
* Created _alpm_sync_find (duplicate code in some places, find_pkginsync
* Minor const correctness changes along the way
* fixed a couple extra '/' pathing issues (non-issues really)
* removed a duplicate pkg_cmp function
