Nexus 7

Last time i was tinkering with the Nexus 7 (presumably the older
model, not the Nexus 7HD), most things were working, except there was
an undiagnosed problem with hybris and the nexus 7 hwc. The nvidia
drivers use a fair amount of the pthread api that the other drivers
don't use (such as process-shared mutexes), which requires special
workarounds in libhybris. They are probably the trickiest drivers in
that regard.

 A few months ago, I could get things to work by forcing the backup
display mode. I'm reworking the hwc code a bit (it has become a small
mess), so maybe I could give a try at some point.
