Replace custom copy of GetReq macro with call to Xlib 1.5's _XGetRequest
xvproto.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.
Also clears clang warnings repeated for every request function:
Xv.c:137:5: warning: cast from 'char *' to 'xvQueryExtensionReq *' increases re
quired alignment from 1 to 2 [-Wcast-align]
XvGetReq(QueryExtension, req);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./Xvlibint.h:52:8: note: expanded from macro 'XvGetReq'
req = (xv##name##Req *)(dpy->last_req = dpy->bufptr);\
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Xv.c:137:5: warning: implicit conversion loses integer precision: 'int' to 'CAR
D8' (aka 'unsigned char') [-Wconversion]
XvGetReq(QueryExtension, req);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./Xvlibint.h:53:30: note: expanded from macro 'XvGetReq'
req->reqType = info->codes->major_opcode;\
~ ~~~~~~~~~~~~~^~~~~~~~~~~~
