Add Stock Reference Diff (frameworks_av)

-This was created by diffing the seeked lource against AOSP
android-4.1.1_r1 tag.

-It's disabled and only here for reference purposes.
patch: AV REWORK

-Based on my Stock-Reference-Diff and did my best to resolve rejects
and conflicts.

-Did not include changes in the media/libstagefright/codecs folder.

-Removed fmradio stuff.

-NOTE: does not seem to actually fix or improve anything at all. Some
things in here my be superfluous. Also not properly isolated, so don't
include in multidevice source base.
patch: disable old av patch.
