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.

Bump all ports that depend on Qt5.

* 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.

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
PKGNAMEPREFIX but are flavored.
USES=python now also exports a PY_FLAVOR variable that contains the
current python flavor. It can be used in dependency lines when the
port itself is not python flavored. For example, deskutils/calibre.
By default, all the flavors are generated. To only generate flavors
for the versions in PYTHON2_DEFAULT and PYTHON3_DEFAULT, define
BUILD_DEFAULT_PYTHON_FLAVORS in your make.conf.
In all the ports with Python dependencies, the *_DEPENDS entries MUST
end with the flavor so that the framework knows which to build/use.
This is done by appending '@${PY_FLAVOR}' after the origin (or
@${FLAVOR} if in a Python module with Python flavors, as the content
will be the same). For example:
RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}

Poudriere in particulr did not properly handle DEPENDS_ARGS which
made these ports not properly install dependencies. That bug
is being addressed along with adding FLAVORS support to it.

- Add PYTHON_PYOEXTENSION and PYTHON_SUFFIX
- Add PYTHON2 and PYTHON3
- Respect PYTHON_VERSION
- Rename PYOEXTENSION to PYTHON_PYOEXTENSION
This change would help:
- Build databases/postgresql*-plpython with Python 3
(It has PLIST issue since bsd.python.mk to Uses/python.mk transition)
- Simplify Makefile

So standardize on that, and move them to the end of the file when necessary.
Also fix some more whitespace, and remove more "signature tags" of varying
forms, like -- name, etc.

A few other various formatting issues
rpCalc started out as a little program written to try out various
Python GUI toolkits. But I ended up using it all the time (it's
much quicker to pull it up than to pull an actual HP calculator
out of the desk), and I made several improvements. So I decided
to make it available to others who also like RPN calculators.
