Decouple lockBuffer from dequeueBuffer. Add lock_buffer to preview_stream_ops,
so HALs will be fully in charge of managing buffers.

-- when the camera HAL allocates memory
-- it requests is as N buffers by S bytes each
-- it may specify a file descriptor to get mmapped; if -1, then we use ashmem
-- when issuing data and data-timestamp callbacks, the camera HAL specifies a
buffer index
-- range checking is performed on the buffer indices
-- memory requested by a camera HAL is not incStrong'ed, and needs to be
expliciftly released by the camera HAL (by calling the release method on the
camera_memory_t handle)

This patch changes CameraService to load a camera HAL module, instead of
linking directly against a library that implements the CameraHardwareInterface
class.
CameraHardwareInterface no longer defines the API to the camera HAL. Instead,
this is now in HAL header hardware/camera.h. We keep CamerHardwareInterface as
a class local to CameraService, which wraps around the new HAL calls. In the
future, we may remove this class entirely and have CameraService call the HAL
methods directly.
