Split the signal-handler's lastSlave out into a separate variable.

Browse source 
dev->u.lastSlave was not signal safe since it was accessed by the DIX and
during signal handling.
Replaced with:
'dev->last.slave' for the signal handler's lastSlave (used to generate
                  DeviceChangedEvents), .
'dev->u.lastSlave' for the DIX lastSlave (currently only used in
                   change_modmap)
