Subject: cam: Turn BufferWriter into a FrameSink
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make the BufferWriter class inherit from FrameSink, and use the
FrameSink API to manage it. This makes the code more generic, and will
allow usage of other sinks.
