PyQt: Update sip to 6.5.0, reintroduce sip4 and simplify PyQt framework.

SIP:
As mentioned in the update from sip to sip5, this is a transitional version
to remove what is deprecated in sip4.
Sip6 completely removes the deprecated parts.
Unfortunately, some ports — mostly cura things — can not use sip6, so we
reintroduce sip4.

PyQt:
At the same time, we took the opportunity to simplify PyQT and propose only one
package as for devel/pyside2. */py-qt5-* have been merged — excepted chart,
networkauth and webengine — into devel/py-qt5-pyqt.

This allows us to be in adequacy with the packages that the author of these

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

Update qscintilla2 to 2.11.6

Remove empty PY_ENUM34 from ports using Python 3.6+

Update Qt/PySide2 to 5.15.2 / PyQt to 5.15.1 / SIP to 5.4.0
This commit combines several updates.

- Update Qt to 5.12.2
- Update PyQt to 5.15.1
- Since PySide 5.15.1 is broken with Qt 5.15.2, so PySide and Shiboken are also
updated to 5.15.2.
- Update sip to 5.4.0

SIP is a collection of tools  to create Python bindings for C and C++ libraries
and used by PyQt and wxPython. There are some changes with sip5 [1]:
- python 3.5+ is required
- sip drops support of old deprecated methods as sipdistutils & cie.
- this version breaks also PyQt5 extension ABI. SIP files will be installed in
${PYTHON_SITELIBDIR}/PyQt${_PYQT_VERSION}/bindings
- some ports will use the new pyqtbuilder package with the pyproject.toml setup.
Instead if the project have a setup.py, you should use sip-build to build it.
- if a port needs sip, it should also needs pysip. BTW, py-qt5-core requires
pysip, so that should be enough for PyQt packages.

Update PyQt to 5.15.0, py-sip to 4.19.24 and qscintilla2 to 2.11.5

- Update PyQt to 5.15.0, py-sip to 4.19.24 and qscintilla2 to 2.11.5
- Use pypi for PYQT [1]
- Add devel/py-qt5-sip (Don't use it for now. It will be used in future updates
of PyQt with py-sip >= 5)
- Add missing py-qt5 ports: comms/py-qt5-sensors, devel/py-qt5-location,
devel/py-qt5-remoteobjects, net/py-qt5-networkauth
- Strip libs
- Refactor *_PATH and *_PORT parts

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.

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

PyQt: Unconditionally install the .pyi files

r460809 started installing .pyi with the %%PYTHON3%% substitution in the
plists. Support for .pyi files was added in Python 3.5, and PyQt's configure.py
only installs the files on Python >= 3.5.

This patch removes the version checks from configure.py (the files are just
unused in earlier Python versions), as it is easier than checking Python 3's
version in each PyQt port's Makefile (or to add the logic to Mk/Uses/pyqt.mk).

Convert Python ports to FLAVORS.

  Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
