* qatar/master:
ARM: ac3: update ff_ac3_extract_exponents_neon per 8b7b2d6
ARM: NEON optimised vector_clip_int32()
swscale: disable full_chroma_int when converting to non-24/32bpp RGB.
suggest to use av_get_bytes_per_sample() in av_get_bits_per_sample_format() doxy
ffmpeg: use av_get_bytes_per_sample() in place of av_get_bits_per_sample_fmt()
put_bits: remove ALT_BITSTREAM_WRITER
put_bits: always use intreadwrite.h macros
libavformat: Add an example how to use the metadata API
doxygen: Prefer member groups over grouping into modules
doxygen: be more permissive when searching for API examples
avformat: doxify the Metadata API
lavf: restore old behavior for custom AVIOContex with an AVFMT_NOFILE format.
lavf: use the correct pointer in av_open_input_stream().
avidec: infer absolute vs relative index from first packet
