Replace custom copy of GetReq macro with call to Xlib 1.5's _XGetRequest

XvMCproto.h names don't match those required by the Xlibint.h GetReq*
macros, but at least we can rely on the _XGetRequest function for the
bulk of the work now, instead of duplicating it.

Continues to use sizeof() instead of SIZEOF() due to stray ; on the
end of many sz_* definitions in XvMCproto.h, but I've verified the
sizes are the same with both methods.

Also clears clang warnings that were repeated for every call:

XvMC.c:79:5: warning: cast from 'char *' to 'xvmcQueryVersionReq *'
  increases required alignment from 1 to 2 [-Wcast-align]
    XvMCGetReq(QueryVersion, req);
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./XvMClibint.h:16:8: note: expanded from macro 'XvMCGetReq'
        req = (xvmc##name##Req *)(dpy->last_req = dpy->bufptr);\
              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
XvMC.c:79:5: warning: implicit conversion loses integer precision:
  'int' to 'CARD8' (aka 'unsigned char') [-Wconversion]
    XvMCGetReq(QueryVersion, req);
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./XvMClibint.h:17:30: note: expanded from macro 'XvMCGetReq'
        req->reqType = info->codes->major_opcode;\
                     ~ ~~~~~~~~~~~~~^~~~~~~~~~~~
