devel/qscintilla2*: Flavorize ports

Mk/Uses: always use colon for build/run suffix

Most USES use a colon for build/run(/test) suffixes. Change kde.mk,
qt.mk and pyqt.mk to do the same, and update all ports using that.

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.

PyQt5: Update PyQt5 to 5.15.3, QScintilla2 to 2.12.0, py-qtbuilder to 1.9.0

* PyQt5: update to 5.15.3

This is a minor feature and bug-fix release. There are corresponding releases of
the other PyQt5-related packages.

 - Added the missing QImage.setAlphaChannel().
 - Support for the QtNetworkAuth library has been moved to a separate
PyQtNetworkAuth package.
 - Wheels no longer bundle the corresponding Qt libraries and instead
automatically install them from an external wheel.

* QScintilla2: update to 2.12.0

This adds support for Qt6 and removes support for Qt4.

 - Change the new distname (again)i due to a conflict
 - Use the new sip-build system

* devel/py-qtbuilder: update to 1.9.0
* devel/py-sip: fix flavor for sip-distinfo

Add USES=xorg USES=gl, ports categories d

Add USES=xorg, USES=gl and in a few cases USES=gnome to ports in categories
starting with 'd'.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

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

pyqt: Change install directories for Python flavor support

* PyQt could not be installed for multiple Python versions at
  the same time, as there were conflicting files.

  This patch creates Python-version versioned directories for
  all these, and further installs binaries with a version number.

* Note, there might be some hickups for software that depends on
  on of the .so's provided by PyQt5, which might not be found
  anymore autmotically, and maybe need some LD-flaggery.

* Update PyQt5 to 5.10.1

* Mark www/py-qt5-webengine broken. It is unforuntately no longer
  compatible with the old qt5-webengine-5.9.4 we ship.

Update QScintilla 2.10.2.

Upstream has renamed its libraries and we no longer need to patch
devel/qscintilla-qt5 to create a library whose name does not conflict with
devel/qscintilla's. However, the library names are different so we need to bump
PORTREVISION in several ports (the SOVERSION has changed too).

Thanks to antoine for the exp-run.

At very long last land PyQt5 5.5.1 ports.

Add the required bits to Uses/pyqt.mk along with all the PyQt5 ports.
Thankfully this commit is mostly adding new ports, as the hard work was
already done in r403297 and r403662.

Huge kudos to Tobias Berner <tcberner@gmail.com> and, most importantly,
Guido Falsi (madpilot@) for their initial work on these ports (see D2910 in
Phabricator for an earlier version of the PyQt5 patch set).
