Merge libavcore into libavutil

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody...

Use the new libavcore audio channel API.

This also allows to remove a linking dependency of libavfilter on

Implement functions:
av_get_sample_fmt_name()
av_get_sample_fmt()
av_get_sample_fmt_string()

Remove explicit filename from Doxygen @file commands.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Remove the 3-front-channel layout from the list of channel layout
aliases. Calling this "surround" is confusing and questionable.
