Close bitstream buffer shared memory handles on Android.

AndroidVideoDecodeAccelerator would clear references to pending
bitstream buffers in ::Reset and, implicitly, in the destructor.
However, each of those may have a file descriptor for shared memory
that isn't closed.  During a seek, for example, this can cause leaks.

This CL wraps the queue of pending bitstream buffers with a new
BitstreamRecord type, which has a unique_ptr to the (unmapped)
shared memory region, if any.  This will automatically close the
underlying handle when the unique_ptr is released.  Note that no
expensive operation is performed in creating the shared memory
region.  Unless it is later mapped, it just keeps the handle
and ::close()s it on destruction.
