Fix XIEventMask to work on any architecture

Browse source 
The mask part of an XIEventMask struct is actually not a pointer to an
integer containing the mask, but rather to an array of bytes each
holding 8 bits of the mask, with the first byte holding bit 0-7.
Therefore the old code would only work on little endian arches.
