[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.
