Keep only the plain C code in the main rgb2rgb.c and move the x86
specific optimizations to x86/rgb2rgb.c
Change the initialization pattern a little so some of it can be
factorized to behave more like dsputils.

The functions are already av_ prefixed and sha1 header is already provided.
Install libavutil/{aes,sha}.h

ff_get_wav_header is reading data from a WAVE file and then uses it
(without validation) to malloc a buffer. It then proceeded to read
data into the buffer, without verifying that the allocation succeeded.

To address this, change ff_get_wav_header to return an error if
allocation failed, and adapted all calling code to handle that error.

The mpegts muxer does not set the stream time base using
av_set_pts_info, but expects it to have the default value of 1/90000.
If the calling code changes stream pts before writing the header,
other muxers override the time base at that point (like mpegenc.c).

Also rename the incorrectly named enc_bitrate to enc_mode, use the
enc_bitrate variable for storing the last chosen bitrate.

This avoids continuous warning log messages if not using an
exactly matching bitrate, while still allowing changing bitrate
at any point.

Include VisualOn to clarify the codec name, but remove the
actual library name from the user-friendly description.
Also mention Android, to clarify which VisualOn implementation
this refers to, since they do sell other variants of the same
code, too.

It's been deprecated only a few months ago, long after 0.6.

No decoder uses the supposed replacement, request_channel_layout, yet.

Those were moved to libavutil only recently.

They've been deprecated very recently.

Stop the avio input at a point where amf_parse_object can
continue parsing the end of the object seamlessly, when all
data is available.

If unsupported data is encountered within the keyframes object,
try seeking to the start of the keyframes object - if the seek
back was successful, the caller can continue parsing the rest
of the AMF data.
