Camera3: add camera3 buffer manager support
* Add camera buffer manager for buffer allocation and sharing management across
multiple streams. Only gralloc v0 implementation is done, v1 implementation is
pending. With this, the max mem footprint for multiple streams in the same
stream set will be the max buffer count x max buffer size.
* API1 client will still use the old bufferQueue code path, buffer manager
is only targeting at API2 clients.
* Prepare and teardown should work with buffer manager.
* Some existing code typo fix and cleanup (to fix the compiling warnings).
