Replace "The segmenter muxer" with "This muxer". The "segmenter muxer"
was never defined before, and thus it is a slightly ambiguous term.

In particular, reference segment muxer and clarify difference between
segment filename number and playlist sequence number.

Should fix trac ticket #2601.

- do not allocate resample dst buffer when resample is off
  - free sample buffers in addition to freeing data pointer arrays

We generate S16 samples and we should allocate the right buffer

This reverts commit 792845e436ddc5f3ce11ba02535a3372919061f2, reversing
changes made to 1d6666a6b8.

Bumping libavutil requires all libraries that use libavutil to have their
major version bumped (yes breakage has been confirmed this is not a hypotheses)

One case of breakage is due to new types being added to AVOptions and
applications that linked to old libavutil and libswresample
then trying to use old libavutil (its soname changed so the old isnt updated)
and new swresample (its soame didnt change so it is updated)
the new swresample contains AVOption types that the old libavutil doesnt
know of thus the application attempting to access these avoptions
fails

AVOptions are used by all libs so the issue can potentially happen with
any other lib, libswresample was just the first that showed the problem
ive not checked if the other libs are affected currently by the same issue
or not

Also in addition to AVOptions, AVFrames are also defined in
libavutil, bumping it without all libs that use AVFrames could lead to
serious inconsistencies when 2 libs/app end up using 2 different libavutils

The alternative of bumping all is still possible after this revert, if it
turns out to be the preferred solution

Also deprecate Author, Comment, Copyright, and Title options, and update
docs to use the new Metadata option.

Fix broken != 0 check.

This is useful for debugging.
