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.

When the cursor is disabled, raw (unscaled and unaccelerated) mouse motion can

Raw mouse motion is closer to the actual motion of the mouse across a surface.
It is not affected by the scaling and acceleration applied to the motion of the
desktop cursor. That processing is suitable for a cursor while raw motion is
better for controlling for example a 3D camera. Because of this, raw mouse
motion is only provided when the cursor is disabled.
