In video4linux2, in the case the timebase value in ap is 0/0, read the
timebase value already set in the driver, and set it back in the codec
stream, rather than leaving the invalid value of 0/0.

In particular, fix ffmpeg grabbing timestamps when the timebase value...

Return pkt->size in v4l2_read_packet().
mmap_read_frame() takes care of ensuring that the packet size
is correct.

If AVPacket->data == NULL, the packet does not contain any buffer to
be freed.
This fixes a double free on exit.

Use avcodec_check_dimensions() for checking the frame size validity.
The v4l.c check is moved after the eventual automatic size detection,
so the check in that case is performed on the new set values.
