x11-toolkits/qt5-canvas3d: remove port (follow up to r513447)

In r513447 when Qt5 was upgraded to 5.13, the port was unlinked but the removal
did not make it.

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.

Update Qt5 to 5.12.1

Release announcement:
  https://blog.qt.io/blog/2019/02/01/qt-5-12-1-released/
Changelog:
  https://wiki.qt.io/Qt_5.12.1_Change_Files

- A change was required to qt-dist.mk to always pass LOCALBASE to qmake,
  as Qt5 has been installed to a prefix for some time now, there should
  not be any harm in that, with respect to it picking up installed versions
  of itself during build.

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

Merge lang/qt5-qml and x11-toolkits/qt5-quick into x11-toolkits/qt5-declarative

- There was no obvious reason to split these ports, and it makes
  porting simpler; the set of ports using either mostly coincided.

Replace bsd.qt.mk by Uses/qt.mk and Uses/qt-dist.mk

From now on, ports that depend on Qt4 will have to set

ports depending on Qt5 will use
	USES=		qt:5

Update the Qt5 ports to 5.10.1.

The work was done by tcberner and myself, with thanks to antoine for the
exp-run.

Not a lot to report compared to other Qt5 updates:
* net/qt5-network is still broken with LibreSSL. I said this in a commit
  message ages ago but it bears repeating: upstream is open to adding support
  for LibreSSL, but someone needs to step up to maintain it upstream, otherwise
  things will continue to be broken all the time.
* www/qt5-webengine is a huge monster that is terrible to update, just like
  www/chromium itself is. We (kde@) have decided to keep using the 5.9 series
  for the time being, as it should be compatible with the rest of Qt anyway. It
  was updated to 5.9.5, the latest 5.9 release at the time of writing.

Fix permissions in installed Qt5 header files

For the qt5-* ports bsd.qt.mk sets EXTRACT_AFTER_ARGS, and
thereby does not get the normal default value of
      --no-same-owner --no-same-permissions
passed when extracting. This lead to for example header files
being installed (i.e. copied), with permissions group write
permissions.

Manually append that to the bsd.qt.mk shenanigans (also do the
same in www/qt5-webchannel, which opts out of the bsd.qt.mk value)

Update the Qt5 ports to 5.6.1.

This took longer than expected, but there are quite a few changes to the
existing ports and a few new ones.

General upstream changes:
- Starting with Qt 5.6.2, Qt will fail at configuration time if LibreSSL is
  being used. According to the discussion here:
  https://codereview.qt-project.org/#/c/154800/
  The Qt project is not opposed to LibreSSL, but does not want to mix
  support for it into the OpenSSL backend code, especially as they move
  towards supporting OpenSSL 1.1.
  People interested in LibreSSL support are welcome to submit a separate
  backend upstream, but are expected to maintain it. We (kde@) are not
  opposed to carrying some patches authored by others in the future, as long

As usual, huge thanks to Tobias Berner (tcberner@gmail.com) for all his work
on these ports in kde@'s experimental area51 repository. He's the one who
started the update and did a lot of the initial work on Qt 5.5. Ralf Nolden
(nolden@kde.org) has contributed the initial version of most of our new Qt5
ports.

Also thanks to Yuri Victorovich (yuri@rawbw.com) for contributing PR 205805
with his own patch for the 5.5.1 update. Some of his changes there prompted
