9187f40e92 avformat/http: Ensure same protocol in ff_http_do_new_request2 
This can happen for HLS with AES-128 at the middle of m3u8, so old
protocol is https while new protocol is crypt+https.

And change the log level from ERROR to INFO when protocol/host/port
don't match. User should prepared for this function to fail and
retry with new connection.

25812d3033 avcodec/bsf/h264_mp4toannexb: Fix mixed bitstream format 
This bsf converts AV_PKT_DATA_NEW_EXTRADATA side data in avcc format
to in-band annexb format. However, the side data wasn't been removed
and copied from input packet to output packet. So the output packet
has mixed bitstream format. We don't support mixed bitstream format.
For example, h264_metadata report error in the following case:

ffmpeg -i foo.flv \
  -bsf:v "h264_mp4toannexb,h264_metadata" \
  -c copy -f null

This patch removed NEW_EXTRADATA side data after process.

This patch also add a check so only NEW_EXTRADATA in avcc format is
processed. NEW_EXTRADATA in annexb format is copied to output as is.

e0df21b8c3 avcodec/webp: Switch to ff_vlc_init_from_lengths() 
The earlier code would traverse over the code lengths
mutliple times (namely max_length + 1 times - once to get
the maximum length and once for each max_length to assign
codes) before calling ff_vlc_init_sparse() (which may traverse
them twice and sort them). The new code only traverses them once
(+ the one time in ff_vlc_init_from_lengths()).

d60445258c avcodec/webp: Check more directly for invalid codes 
Don't rely on invalid codes leading to get_vlc2() returning
-1, which then gets converted to an uint8_t, i.e. to 255
and runs afoul of a length check later. After all, get_vlc2()
could be changed to return something else which may
be valid when cast to uint8_t.

6676038b23 avcodec/cbs: Use put_bits63() 
It is better when BUF_BITS == 64 (i.e. on x64), because
the underlying put_bits can then handle 0..63 bits naturally.
It does not worsen the code when BUF_BITS != 64, because
the compiler can optimize this to the same code as now
(due to the assert).
