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.

Generalize writing of any number of qtables. Don't manually write
16 bit values in two separate calls.

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.

A decoded and resampled audio frame may not fit in the current size which is
not handled by the current code causing out of order waveform displays or even
channel mixups. A todo is added because this part can certainly be improved to
consume less memory but work reliably for any frame size.

It was theoretically possible for pictq_prev_picture to fill the picture queue
which may have caused problems when a write to the queue was still in progress.

This also makes sure the aspect ratio of the picture is set before allocating
the picture, this way video_open can calculate with the correct aspect ratio
even for the first frame.

The new name is more consistent with the codebase, and more
self-consistent with the libswscale API.

Favor the use of plain AVPicture over AVFrame, especially when the use of
AVFrame is not required like in the case of tmp_picture.

Also adopt more straightforward names, to avoid frame/picture confusion.
