Rename raw input to raw mouse motion, cleanup

Browse Source 
This renames 'raw input' to 'raw mouse motion' as there are other kinds
of raw input.  The update path is restructured to avoid reinitializing
all of disabled cursor mode.  Modification of shared state is moved out
into shared code.  Raw mouse motion is disabled by default for
compatibility.

Related to #1401.
