LGTM for what it is (which is awesome) but Sonny Rao was trying to revive
player_x11 --enable-openmax.  You should talk to him off-reviewlog about how sad
this will make him (if at all).

Looks like this CL has broken the heapchecker bot, which fails to compile
media_unittests now.
Is there any particular reason for not linking media_unittests with
liballocator?
