libavformat/riff.c has been writing channel_layout for as long as
the field exists.

Fixes memory leaks which are the result of overwriting already-initialized
MDCT contexts during context reinitialization, e.g. in valgrind
fate-aac-latm_000000001180bc60.

Some compilers choke on -Wall, so only add the flag after checking it works.

This format is still used by e.g. OS/2.

This explicitly disables threading for encoding as slices are otherwise
automatically activated.  This should be dropped once option resetting
between files is fully implemented.

This adds a comment field to the report header, suitable for
extra information not covered by the automatic fields.

This is useful e.g. for building in a different filesystem than
where the source is kept.

Since a private class is set for this muxer, the callers will
assume that the private data starts with an AVClass pointer.
If no such member exists, the first few bytes of the struct
will be overwritten, and the class pointer may be broken at
any later time.

Require the presence of opencv/cxcore.h in place of opencv/cxtypes.h,
which has been removed. Fix compilation with libopencv > 2.1.0.

Fix trac issue #221.

Fix warnings:
cmdutils.c: In function ‘opt_default’:
cmdutils.c:304: warning: initialization discards qualifiers from pointer target type
cmdutils.c: In function ‘set_context_opts’:
cmdutils.c:431: warning: passing argument 2 of ‘alloc_priv_context’ discards qualifiers from pointer target type
cmdutils.c:414: note: expected ‘struct AVClass *’ but argument is of type ‘const struct AVClass *’

Also remove -x264opts item from the ffmpeg manual, since it belongs to
the encoders section.

Make Audio Encoders a separate chapter, and decrese the contained
sections level by one.

Improve rendering, and improve consistency with the other parts of the
manual.

Muxers are not used by ffprobe.
