libx11: Backport _XGetRequest API
This API is relatively new and will be in next release of libX11
this is needed for OE qemu-native which links to libx11-native
but uses libGL from build system and herein lies the problem
if you have bleeding edge distro e.g. ubuntu 12.04(development)
libGL.so expects this API to be present. Backported to 1.4.4
thusly
