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.

While here, chase some KDE4 ports and functionality, these are scheduled for
removal on 2018-12-31. Change the default option/flavor to QT5 where applicable
or use alternative toolkits like GTK.

From now on, ports that depend on Qt4 will have to set
USES= qt:4
USE_QT= foo bar
ports depending on Qt5 will use
USES= qt:5
USE_QT= foo bar

Plasma5 ports
At the moment KDE ports use bsd.kde4.mk to handle their dependencies. When
working on the ports for KDE Frameworks and Plasma5 it seemed to be more
reasonable to create a new kde.mk instead of adding an bsd.kde5.mk.
The kde.mk in this review is a stripped down version of the one we are using in
the KDE Test repositories plasma5 branch [1] to only contain the parts relevant
to the current KDE4 ports in the portstree [2].
Changes to the KDE Ports needed by this:
Replace USE_KDE4 by USE_KDE [3]
Add USES=kde:4 [4]
[1] http://src.mouf.net/area51/view/branches/plasma5/KDE/Mk/Uses/kde.mk
[2] The version in the plasma5 branch also handles frameworks/plasma5 and
handles MASTER_SITES via a KDE_DIST variable similar to bsd.qt.mk for Qt
Ports -- I chose to leave this out for now, as the diff is already large
enough.
[3] I chose USE_KDE instead of USE_KDE4, USE_KDE5, USE_KDEX as the version we
want is already specified as argument to kde:<arg>
[4] For KDE Frameworks and Plasma5 ports this would be kde:5

- Use qt4-linguisttools instead of qt4-linguist for *.ts files.
- Depend on qt4-xml and qt4-gui even when KDE is selected (they are used anyway).
- Use OPTIONS helpers where possible.
