[Mesa-stable] [PATCH 0/4] egl/*: Set disp->DriverData to NULL on error

[Nicolas Boichat]

egl/x11 fixup has already be sent here:
https://patchwork.freedesktop.org/patch/101934/

Compile-tested only (on android only).

I was first thinking of modifying most functions in egl_dri2.c to take in
dri2_egl_display *dri2_dpy instead of _EGLDisplay *disp as parameter, so
we do not need to set disp->DriverData early in the dri_initialize_* functions.

But there are some functions that do need disp as well:
 - dri2_add_config, to call _eglInitConfig (disp->DriverData does not need to be
   set), and to check if extensions are supported.
 - dri2_setup_screen (similar reasons)

Ideas to untangle this are welcome. In the mean time, this patch series should
fix crashes and a piglit test.
