audio/opus: bump consumers after update to 1.4

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/jack: Update to Jack2: 0.125.0 -> 1.9.16

Big thank you to Florian Walpen <dev@submerge.ch> and
Goran Mekić <meka@tilda.center> for working on Jack2.

Remove # $FreeBSD$ from Makefiles.

- Define LICENSE (MIT)
- Remove MAKE_JOBS_UNSAFE that was added in r415925: while it's true that
  most plugins we have in the tree are make(1) jobs unsafe (and, in fact,
  come from the same upstream with nearly identical (and broken) Makefile
  logic), this particular port contains single C source file and we build
  and install it directly via port's Makefile (in situ), so it can hardly
  be make(1) -jX unsafe

Mark the remaining three deadbeef plugs as not jobs safe

Today the quick-search plugin failed to build due to concurrency issues,
making it the 5th of 7th plugins to do so.  Mark it and the remaining
two plugins as jobs unsafe.

Remove ${PORTSDIR}/ from dependencies, Mk and categories a, b, and c.

Add a port of JACK output plugin for DeaDBeeF music player.  There are few
versions available on the net; this is the only one that seemingly works.
