Basic foreign window support for QNX

Requires a screen with working context permission parsing.  Currently,
all context permission requests fail because the parsing is incorrect.
A context permission is added temporarily to prevent CLOSE/CREATE
events when Qt reparents foreign windows.  Qt does this temporarily
when a foreign window is wrapped in a widget.
