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.

[QNX] Introduce proper screen error handling

This patch adds a new function which does the error handling for libscreen calls.
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.
