* Switched some functions to alpm_pkg_get_* usage as I came across them

* Added some provision switching hackery.  This could probably use some
  refactoring,.. it solves the following case:

    pkg1 and pkg2 provide 'foo' and are both installed
    pkg3 depends on 'foo' and so lists 'pkg1' in the REQUIREDBY db section
    pkg1 is upgraded and no longer provides 'foo'
    ** This code ensures that the REQUIREDBY of pkg3 is updated to require pkg2
       now instead of pkg1
