A multi-channel MPEG encoder, using the ISO13818 standard and the dist10
source code. Multi-channel files may have up to 6 defined channels:
Left(L), Right(R), Center(C), Left Surround (LS), Right Surround (RS) and
a Low Frequency Enhancement channel (LFE).
ISO13818 defines 5 multi-channel modes (on top of the normal stereo mode),
each of these modes may have an optional LFE channel:
3/2: L, R, C, LS, RS
3/1: L, R, C, mono surround
2/2: L, R, LS, RS
2/1: L, R, mono surround
3/0: L, R, C
The "standard" surround sound encoding of "5.1 channels" is achieved by
using mode 3/2 plus an LFE channel.
A multi-channel MPEG file should decode OK on any MPEG decoder. If the
decoder doesn't recognize the multi-channel extensions, then you'll just
get a stereo file containing a down mix of the 5 channels.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

audio/mctoolame*: Deprecate and set expiration date to 2022-09-30
Legacy audio format that never gained any traction. It was occasionally
used for SVCDs but very few players decoded all channels and most instead
only used stereo channels. Last release was back in 2003 and listed as
alpha quality.
Convert ports to use the options helpers in categories [abc]*, and minor fixes.

Differential Revision: https://reviews.freebsd.org/D3412?
Convert audio from USE_GMAKE to USES=gmake
While here:
- Trim headers
- Convert some USE_GNOME=pkgconfig to USES=pkgconfig
- Add some missing pkgconf dependencies
- Convert some USE_GNOME=gnomehack to USES=pathfix
Synchronize mctoolame-decoder and mctoolame-encoder. These ports are pretty
much mimic each other, so it probably makes sense to merge them into one, or
turn into master-slave pair. While here, replace unsafe gets() with fgets().
