85a2653737 Enable running sql model tests in parallel
Each model test gets its own temporary directory, thus there is no problem parallelizing them.

This should reduce the time spent for a testrun of qtbase by around 3 minutes.
When running only the sql tests it saves less since there are no other tests to run in parallel.

The patch introduces following changes:
- Libscreen errors will not crash (qFatal)the application any more but rather post a
warning message.
-With the "flush-screen-context" option the screen_context is always
flushed when a screen function is called. This enables better correlation between the
time an error happens and the time it is logged.

a4ff400e25 Fix application font removal when using FontConfig
This patch fixes an issue when a font that was added with QFontDatabase::addApplicationFont
can not be removed any more.
The reason for that is that QFontconfigDatabase::addApplicationFont adds the font to the FontConfig
application set from where it cannot be removed any more and is picked up every time the font database is
repopulated (e.g. after a call to QFontDatabase::removeApplicationFont).

This also fixes the QFontDatabase autotest which unfortunately does not fail on linux, because it tries
to add "FreeMono" (which in most cases is already there as a system font). So this patch removes FreeMono and adds
LED_REAL as test font.

      ...
  "std::__throw_length_error(char const*)", referenced from:

to the more generic mac/default_post.prf.

bd9e1f3915 Improve direct2d backing store implementation
Add a per-window swap chain to a QPlatformWindow subclass instead of tying
it to the backing store. This is needed to support native widgets (as
opposed to alien widgets).

Change the backing store to draw to an intermediate pixmap and flush to
the requested window by using the per-window swap chain. This also opens
the door for faster window presentation later on by using the swap chain
more intelligently.

Also add a changelog entry for the direct2d plugin, which was omitted
earlier.

a4a174e1a2 iOS: Disable tests for all other modules than qtbase
Instead of sprinkling '!ios' all around the various modules. This is
a bit more fine grained than the CFG_NOBUILD_PARTS += "tests" that we
had in configure.

f550ced3aa Don't rely on makedepend on OS X
It's not shipped as part of the default installation, but the binary
in /usr/X11R6/bin/makedepend exists and will trigger a dialog that
asks you to install X11. This is not needed when we can use the
compiler to resolve the dependencies for us.
