Add lima_query support stub. #9

Closed PabloPL closed 6 years ago

PabloPL commented 6 years ago

This is taken from vc4 driver. I was playing (making some changes etc) with gbm apps from gfx repo and without this i was getting segmentation fault (in cso_save_state method there is call to set_active_query_state which was not set).

How to reproduce it: In gbm-surface-color i tried to add

glScissor(0, 0, 0, 0);
glEnable(GL_SCISSOR_TEST);

And then got segmentation fault

Program received signal SIGSEGV, Segmentation fault.

With this fix, it's not crashing.
