[PATCH 0 of 6] Various patches - debug help, xend fixes and S3 resume fixes (v1).

[Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>]

Hello,

The majority of these patches are for Xend and for some of
the operations it can do. I know that python stack is deprecated
but some distros and companies still use - so it makes sense to carry
them until those companies (cough cough) convert over to xl.

The minority of the patches are:
 - Fix to PAT when resuming from S3 - this is a fix from
   VirtualComputer and the authorship should be theirs.
 - A VGA debug facility when you don't have any other mechanism to
   debug
 - And a fix to the xencommons to load the Xen ACPI processor
   which has been accepted upstream.

Please pull or advice on whether I should split these patches up, etc.
