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.

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

(well) on FreeBSD. Then the port used en embedded copy of QScintilla.
Switch to using the system QScintilla.
This change is triggered by CMake 3.11, which tried to build the embedded
QScintilla slightly differently. That fails because there are header
files declaring enum { SCI_CANREDO = 2016 } *and also* header files
that #define SCI_CANREDO 2016; the include order is very fragile.
Also reported upstream.

DB Browser for SQLite is a light GUI editor for SQLite databases,
built on top of Qt. The main goal of the project is to allow
non-technical users to create, modify and edit SQLite databases
using a set of wizards and a spreadsheet-like interface.
This project has previous been known as "SQLite Browser" and "Database
Browser for SQLite". "DB Browser for SQLite" will hopefully be the
name that sticks. :)
