[MRE] Rebase Xen to upstream stable 4.1.6.1

[Stefan Bader]

MRE Justification:

Impact: Upstream Xen has released a stable update to 4.1.6.1. Since Precise is based on 4.1 it would be gaining us bug fixes without waiting for people to run into them. Like we do with upstream stable on the kernel.

Fix: Replaced the orig tarballs with the contents of the upstream stable release. Dropping patches we have picked up already.

Testing: Upstream automated tests and local half-automated testing (manual preparation of host).

Quantal has the same Xen version but will be out of support soon. So it makes no sense to push for a MRE there.

Hello Stefan, or anyone else affected,

Accepted xen into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/xen/4.1.6.1-0ubuntu0.12.04.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
