Pass argc, argv to the platform plugins.

Allow for parsing of X11-specific arguments like -display,
-geometry. Introduce overload of
QPlatformIntegration::create() with argc and argv
and provide default implementation that calls the old version
(for platforms that do not have argc, argv). Provide default
implementation for the old version returning 0 so that platforms
using the new API compile.
Prototypically implement -display in XCB.
