Here's a few patches to avoid trusting rouge user-space programs
from crashing the host by tricking virglrenderer into calling
unsupported OpenGL functions.

This was initially spotted by Po-Hsien Wang during fuzzing (the
crash in patch #3), the other patches were noticed while reviewing
for similar issues.

Erik Faye-Lund (4):
  protect call to glPrimitiveRestartIndex
  protect call to glDeleteSamplers
  protect gl{Begin,End}ConditionalRendering calls
  protect calls to glPrimitiveRestart on GLES 3.1
