Rename the called dsp init functions to *_init_x86.

The tag @table expects @item to mark entries.

avconv provides an option to set it externally and there isn't a way for
the outer demuxer to report the inner demuxer flag.

Solves a bad interaction between mpegts and x264, but requires
additional setting for the user.

When there is only 1 channel, the planar and interleaved formats of the same
data type should be treated as identical.

This allows failing cleaner and earlier if unable to write to
the output directory.

This allows calling write_manifest from ism_write_header without
a forward declaration.
