The CameraMetadata::updateEntry() functions cast the data pointer to a
void pointer, which is then used internally to call
update_camera_metadata_entry(). If the caller passes a pointer to an
incorrect data type, the behaviour is undefined, with possible crashes
if the incorrect data type is smaller than expected by the Android
metadata library.
To avoid crashes, make all public updateEntry() functions take typed
pointers, and pass the element size to the internal function. The
element size is then checked against the expected size, and an error
message logged if they don't match. This won't catch incorrect data
types that have the same size as the correct type, but will at least
avoid potential crashes.

Previously we had to manually declare the size of CameraMetadata on
allocation, and its count could not be changed after construction.
Change CameraMetadata's behavior so that the user can simply add or
update entries, and the CameraMetadata will auto-resize (double the
size) as necessary. Also remove everything involved with calculating
the initial size for any CameraMetadata instances.

is no need of copying if a caller needs the reference of the

is a caller that copying is required. This changes the return
type of camera() to const shared_ptr&, so that we are able to
