libxshmfence foolishly advertises the type of a fence as 'int32_t *', which
works when the fence is a linux futex. However, that library is going to
change the exported datatype to 'struct xshmfence *', which will provide some
nice typechecking. Anticipate the change by just using 'void *' in mesa, which
works with both the int32_t* and struct xshmfence* versions.

libxshmfence will also be providing a HAVE_STRUCT_XSHMFENCE define, so
we could actually check for that and use struct xshmfence when
available. Just using 'void *' avoids a bunch of clutter, but if
people think they'd rather have extra type checking, I can do the
other version instead.
