Merge in lollipop and attempt to fix merge conflicts

This will probably not compile and may need additional work.
For tracking purposes so we know what might still need looking at
as none of this has been compiled and tested, here is a list of
the merge conflicts that I attempted to fix before pushing this
set of changes:

git pull aosp lollipop-release
remote: Finding sources: 100% (992/992)
