Use RRScreenSetSizeRange in 1.0 compat. Check RRGetInfo for error.

Browse Source 
The RRScreenSizeSetRange function is used externally for 1.2 API drivers,
but can also be used in the 1.0 compatibility code. This also ensures that
the right changed bits are set so that clients are correctly notified when
the range changes.

RRGetInfo can return an error, use that to return BadAlloc to clients
instead of blindly going on with various requests.
