Avoid duplicate emulated mouse events with XInput2

When using a touch screen on a Linux machine, we receive both touch-events
and emulated mouse events from XInput, on top of that we synthesize mouse-
events ourselves for the touch events.

This patch grabs the touch device for touch events whenever it processes
a touch-begin thereby avoiding XInput from synthesizing mouse events.

Fix Qt build when mtdev is detected

If it's detected, we have "mtdev" in QT_CONFIG, not in CONFIG. With
the bad test, libQt5PlatformSupport.prl would not get -lmtdev and, in
turn, the evdevtouch generic plugin would fail to link.

XCB: Fix pixmap leak

In qt_xcb_XPixmapFromBitmap(), a new pixmap is generated for the caller.
This pixmap has to be freed after use. However,
createNonStandardCursor() didn't do this and instead leaked the pixmap.

Move no-pch extra compiler to common features

As we add more classes with RValue ref qualified methods we will need
the same _compat trick and no-pch support as QString.

This patch moves the extra compiler to precompile_header.prf which is
automatically included when pch is used.
