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:

vtest_new_shm called fcntl which failed (-22)

With the main aim of making vtest's usage of virglrenderer more similar
to that of QEMU, this patch sets a backing store to each resource and
reads from or writes to at each transfer operation.
v2: - Instead of adding a callback on resource destruction, free the
iovec when we unref a resource as we know that we won't be doing
anything else with it. (Dave Airlie)
v3: - Store pointers to iovecs in the global to also release them
v4: - Add new commands for resource creation and transfers, to be used
when protocol version >= 1.
v5: - Replaced the global array of iovecs with a hash table because some
es31 tests create thousands of resources and reach any sane limit.

As we don't have yet a proper way of negotiating a common protocol
version to use between clients and the server, we introduce a command
without reply arguments that allows us to figure out if the server is
new enough to handle negotiation of the protocol version.

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.
