* 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
