[Quantal][Pull Request] SAUCE: UBUNTU: (upstream) Modify UEFI anti-bricking code

[Luis Henriques]

BugLink: http://bugs.launchpad.net/bugs/1199401

This set of patches will bring upstream commit f8b8404 "Modify UEFI
anti-bricking code" into the Quantal kernel.  All the required
dependencies have also been pulled in, along with a fix to a buffer
memory allocation.

Most of the backports have been based on Ben Hutchings' backports to
upstream 3.2 kernel.

A good amount of testing has already done by Colin on 5 different UEFI
systems, but some more testing/review is probably required.
