Log Message:
Add a buffer "scale" hint to MouseDevPtr type.  If set, MouseProc() uses it
as a structure size * 4 for the size of the mouse input buffer (Xisb buffer),
else the static size of 64 bytes is allocated.

On LP64, the wscons_event struct is 8 bytes larger.  If more than 2 events
were queued, wsconsReadInput() would get the first 16 bytes of the 3rd event
and thus have bogus events the next time (and until the queue was drained).

Chose this path over handling short reads in wsconsReadInput() so we could
have a buffer large enough to hold more than just 2 events.
