Versioned provisions.
This patch introduces versioned provisions in "provision 1.0-1" format. _alpm_db_whatprovides was modified accordingly (added sync500.py), alpm_depcmp was modified accordingly (add043.py passes now; added add044.py and add045.py). Notes: alpm_db_search now uses the whole versioned %PROVIDES% string in its search. debug logging was simplified in alpm_depcmp. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> [Xavier: fixed a few typos, duplicate const strings with strdup before modifying them, put some debugging back in alpm_depcmp, minor code cleanups (var/function renaming), added a note in PKGBUILD man page.] Signed-off-by: Chantry Xavier <shiningxc@gmail.com> [Dan: made strcmp checks clearer, added a comment] Signed-off-by: Dan McGee <dan@archlinux.org>
