xi2: Handle XIM modules that replace events

Browse Source 
Fixes Bug 645993 - XIM has wierd behaviors. Some XIM modules
filter every key event, possibly replacing it with their own
one. These events usually have serial=0, so make
GdkDeviceManagerXI2 also listen on these.

/* The X input methods (when triggered via XFilterEvent)
* generate a core key press event with keycode 0 to signal the
* end of a key sequence. We use the core translate_event
* implementation to translate this event.
*
* Other less educated IM modules like to filter every keypress,
* only to have these replaced by their own homegrown events,
* these events oddly have serial=0, so we try to catch these.
*
* This is just a bandaid fix to keep xim working with a single
* keyboard until XFilterEvent learns about XI2.
