xfree86: block signals between EnableDevice and first CheckMotion()
Devices usually enable SIGIO processing in EnableDevice. CheckMotion
initialises the pointer sprite, sends Enter/Leave events, etc. This leaves
us with a small window where events may be processed without the sprite or
pointer position (as seen from the protocol) is valid.
Block signals during this window.
