Martin Storsjö 20f325f320 rtpdec_jpeg: Don't needlessly use a bitstream writer for the header
Everything written with this bitstream writer is 8/16 bit units
(except for a pair of 4 bit values), so using a bitstream writer
isn't necessary.

Martin Storsjö 7ef4323405 rtpdec_jpeg: Write the DHT section properly
Currently the size header of the generated DHT section is
incorrect, making the mjpeg decoder just skip it. Since the
written huffman tables are the default ones, this failure had
gone undetected.
