Support building with desktop OpenGL managed via EGL

This mostly replaces lots of QT_OPENGL_ES defines with QT_NO_EGL
instead. It also switches off EGL auto-detection by default. This is
to make sure we default to using GLX on systems with both EGL and
desktop OpenGL. If -opengl es1|es2 or -openvg is specified, then
EGL auto-detection is switched back on (as a requirement. If
configure auto-detects OpenGL ES it also switches on EGL
auto-detection, but failue then just disables both EGL & OpenGL.

As a side effect, this patch also fixes building Qt when both EGL
and glx are avaliable, as they are in Mesa >= 7.8.0.
