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.

[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.]
