Laszlo Agocs e8364f9a4b Enable GL prototypes with recent Khronos headers
Recent Khronos headers decided to break the world by guarding all
function prototypes with GL_GLEXT_PROTOTYPES which has traditionally
been used for extension headers only.

Until this gets corrected - see
https://lists.freedesktop.org/archives/mesa-dev/2016-September/128654.html
- add the define to the config tests and qopengl.h.

While 5.7 already has some of the qopengl.h fixes due to an upgraded
ANGLE shipping with newer headers, this is a cross-platform issue that
will surface everywhere eventually. Therefore we target the full set
of fixes to 5.6.

This time we also make sure the forced define of GL_GLEXT_PROTOTYPES
is removed before including the ext header, thus apps get the ext
protos only if they actually requested them.
