More consistent/readable.

The new function accepts a slightly more intuitive order of paramters,
and returns an error code, thus allowing applications to report a
meaningful error message.

Address trac issue #33.

It's badly documented and does the same thing as -flags global_header,
so it's redundant.

Create a stereo_mode metadata tag to specify the stereo 3d video layout using the StereoMode tag in a matroska/webm video track.

Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

Else a later buffer resize in ffio_set_buf_size() will ABORT.

If done before, some parameters aren't known yet.

With svq3/rtp, initializing before some parameters are known
can lead to calling av_malloc(0), which on OS X currently returns
broken pointers.

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

  LATM/AAC: Free previously initialized context on reinit.
