Juan RP d379d1d44c Implemented blueprint "essential-upgrades".
See https://blueprints.launchpad.net/xbps/+spec/essential-upgrades
for complete information.

Implementation used almost the same code than the pseudo-code explained
in the blueprint. Works really fine, tested with glibc-2.10.1 -> 2.11
upgrade.
