[Piglit] [PATCH 06/14] glx_ext_import_context: Verify function of glXGetContextIDEXT

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

This test fails on NVIDIA's closed-source driver because it segfaults
while trying to glXGetContextIDEXT on a NULL context.

This test fails on AMD's closed-source driver because it hits an
assertion failure in XCB:

xcb_io.c:515: _XReply: Assertion `!dpy->xcb->reply_data' failed.

Signed-off-by: Ian Romanick <ian.d.romanick at intel.com>
