Android: Rework RunForegroundManager (again)
Restore pre-r29562 way of doing compatibility and adapt it to what MediaButtonReceiver looks like. I.e. assume the new API is there, and fall back to the old API if an exception is raised because the API isn't there. The old API still needs to be discovered through reflection because it's removed entirely from Honeycomb. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30165 a1c6a512-1295-4272-9138-f99709370657
