99b49840d3 PermissionCache caches permission checks
This is intended to absorb the cost of the IPC
to the permission controller.
Cached permission checks cost about 3us, while
full blown ones are two orders of magnitude slower.

CAVEAT: PermissionCache can only handle system
permissions safely for now, because the cache is
not purged upon global permission changes.

386a332b4f Make static versions of libutils and libbinder.
Fix some small static-initialization-order issues (and a static-
initializers-missing issue) that result from doing so.  The static
libraries don't actually get used for anything real at the moment --
they're used for perf tests of bug 2660235.
