Exit when QemuPipe is corrupted by GL

Previously when QemuPipe is corrupted, it prints an error message, and
the application will continue to use it, which leads to random behaviour
in GL on the host.

This patch crashes the APP and pops up the crash dialog when the pipe is
(going to be) corrupted. It would happen if the user asks GL to write /
read a NULL pointer (i.e. passing NULL to glGenBuffers). It might also
happen for other unknown reasons.
