447b5b278c mpegvideo_enc: Fix encoding videos with less frames than the delay of the encoder
When the encoder is fed with less frames than its delay, the picture list
looks like { NULL, NULL, ..., frame, frame, frame }. When flushing the
encoder (input frame == NULL), we need to ensure the picture list is
shifted enough so that we do not return an empty packet, which would
mean the encoder has finished, while it has not encoded any frame.

9bc3d3355f avcodec/huffman: replace qsort with AV_QSORT
ff_huff_build_tree uses qsort underneath. AV_QSORT is substantially
faster due to the inlining of the comparison callback. Furthermore, this
code is reasonably performance critical, since in e.g the fraps codec,
ff_huff_build_tree is called on every frame. This routine is also called
in vp6 on every frame in some circumstances.

Sample benchmark (x86-64, Haswell, GNU/Linux), vp6 from FATE:
vp6 (old):
  78930 decicycles in qsort,       1 runs,      0 skips

   9938 decicycles in qsort,    2048 runs,      0 skips
   8043 decicycles in qsort,    4095 runs,      1 skips

vp6 (new):

7c8fcbbde3 avutil/tree: add additional const qualifier to the comparator
libc's qsort comparator has a const qualifier on both arguments. This
adds a missing const qualifier to exactly match the comparator API.

Existing usages of av_tree_find, av_tree_insert are appropriately
modified: type signature changes of the comparators, and removal of
unnecessary void * casts of function pointers.

2ee51ef259 avfilter/vf_deshake: use a void * comparator for consistency
For generality, qsort uses a comparator whose elements are void *. This
makes the comparator have such a form, and thus makes the void * cast of
the comparator pointer useless. Furthermore, this makes the code more
consistent with other usages of qsort across the codebase.

03037a4aad ffplay: use a separate struct for the rescaled YUVA AVSubtitle rectangles
Current code segfaults since the deprecation of AVSubtitleRect.pict because it
freed/realloced AVSubtitleRect.pict.data by itself.

The new code stores the generated YUVA AVSubtitle rectangles in their own
struct and keeps the original AVSubtitle structure untouched, because
overwriting it is considered invalid API usage.

e02dcdf6bb rtsp: Allow $ as interleaved packet indicator before a complete response header
Some RTSP servers ("HiIpcam/V100R003 VodServer/1.0.0") respond to
our keepalive GET_PARAMETER request by a truncated RTSP header
(lacking the final empty line to indicate a complete response
header). Prior to 764ec70149, this worked just fine since we
reacted to the $ as interleaved packet indicator anywhere.

Since $ is a valid character within the response header lines,
764ec70149 changed it to be ignored there. But to keep
compatibility with such broken servers, we need to at least
allow reacting to it at the start of lines.
