Issue #1962 - Update libtheora.

Browse source 
Removed some obsolete patches that were either backports from newer
 svn revisions, or a fix for older, non-applicable assemblers.
Update our own README to account for upstream's migration to git.
I didn't remove the bug 703135 patch as it's for MSVC it seems, and
 we still use MSVC for Windows.
Also deleted some unneeded upstream code deleted by Mozilla as well.
