[Piglit] [PATCH 09/14] glx_ext_import_context: Verify glXImportContextEXT across two processes

[Ian Romanick]

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

This test fails on NVIDIA's closed-source driver because they do not
generate a GLXBadContext error the invalid context ID 0 is imported.
They do, however, correctly generate the error when 0xDEADBEEF is
imported.

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.
