A fuzzer which works by fuzzing output that can be captured via vtest
using the VTEST_SAVE env variable for virgl_test_server. That input can
be used as a seed corpus to get better coverage than purely randomly
generating command streams.

Right now, let's just support memfd. We could support other shared
memory types later.
vtest adaption based on following QEMU files:
qemu/include/qemu/memfd.h
qemu/util/memfd.c
v2: - memfd --> shm
- don't call fcntl(fd, F_ADD_SEALS) because it fails under callgrind
for some reason:
==8161== Warning: unimplemented fcntl command: 1033
vtest_new_shm called fcntl which failed (-22)

1) We use the preprocessor flag HAVE_EPOXY_GLX_H, but never
set it.
2) WITH_GLX diverges with HAVE_EPOXY_EGL_H.
3) virgl_test_server needs to link with X11 when using a GLX
backend.
To fix this, query epoxy for GLX support and allow the user to
disable it as well.
TEST=./autogen.sh --disable-egl
For the same glmark2 "build" test, perf reports about half
instructions.

The idea is to have a unix socket and possible shmem protocol
between a renderering server and local gallium sw driver.
This could be used to validate virgl without qemu with piglit.
