Connor O'Brien 5b3d110f34 ANDROID: proc: Add /proc/uid directory ...

Add support for reporting per-uid information through procfs, roughly
following the approach used for per-tid and per-tgid directories in
fs/proc/base.c.
This also entails some new tracking of which uids have been used, to
avoid losing information when the last task with a given uid exits.
