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.

Approved by:		portmgr (tcberner)

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.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

cleanup: remove transitive py27 deprecation (www/qt5-webengine)

One more small cleanup, forgotten yesterday. Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

Mark ports recursively depending on Python 2.7 for expiration on June 23.

For ports optionally dependending on Python 2.7, just mark those options
as expired. Remove konquerer from the x11/kde-baseapps metaport and bump
its PORTREVISION.

Add education virtual category

PR:		248402
Submitted by:	PauAmma

Recently, kdeedu gained a dependency on math/kig, which brings in some heavyweight dependencies:

devel/boost-python-libs
  devel/libunwind
  math/blas
  math/cblas
  math/lapack
  math/metis
  math/openblas
  math/py-numpy
  math/suitesparse

This is particularly painful on powerpc64, where openblas does not even
build (yet).

This patch turns on option KIG on x86 only.

The impact on arm is TBD.

Update KDE Applications to 18.12.2

Fix Qt5 symbol version scripts to put the catch-all clause first.  When a symbol matches multiple clauses the last one takes precedence.  If the catch-all is last it captures everything.  In the case of Qt5 libraries this caused all symbols to have a Qt_5 label while some should have Qt_5_PRIVATE_API.  This only affects lld because GNU ld always gives the catch-all lowest priority.

Older versions of Qt5Webengine exported some memory allocation symbols from
the bundled Chromium.  Version 5.9 stopped exporting these [1] but the
symbols were kept as weak wrappers for the standard allocation functions to
maintain binary compatibility. [2][3]  The problem is that the call to the
standard function in these weak wrappers is only resolved to the standard
function if there's a call to this standard function in other parts of
Qt5Webengine, because only then is there a non-weak symbol that takes
precedence over the weak one.  If there's no such non-weak symbol the call
in the weak wrapper resolves to the weak wrapper itself creating an infinite
call loop that overflows the stack and causes a crash.  Some of the
allocation functions are variants of C++ new and delete and it probably
depends on the compiler whether these variants are used in other parts of
Qt5Webengine.

Remove the weak wrappers (make them Linux specific).  This isn't binary
compatible but we are already breaking that with the changes to the symbol
versions.

Update KDE Applications to 18.04.0

* Pin multimedia/kdelive at 17.12.3 until we import the mlt update from the dev-repo.

Add the KDE metaports

* add multimedia/dragon (was missing)
* add the meta ports for the categories
* add x11/kde5 [yeah, we know, there technically is no "KDE 5"]
