It's a pkg-config 0.28 feature and Travis-CI ships with an older version.
Do the trivial task of writing it out manually ;-)

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.

Make EGL optional since it's use in virglrenderer isn't always
compatible with drivers on linux, for example nVidia does not
provide a GBM implementation (used by virgl_egl*) with their
linux drivers.

If libepoxy is installed in a non-standrad location AC_CHECK_HEADERS_ONCE will
fail to find the header. I did it this way because trying to get
AC_CHECK_HEADERS_ONCE to find it involved setting and unsetting CFLAGS.

apitrace & epoxy with EGL don't work nicely together, using glx works
around this issue for now (disabled by default).

We use the library unconditionally, however not check it in
configure phase. Let's produce an error there and not at
compilation phase.
And while at it, drop -ldl from LDFLAGS too. I suspect it's
coming from the same source because in the gbm pkg-config file
private libs are to be linked with dl. But not only we are not a
gbm private library, we don't use dl*() anywhere.

Instead of polling the fences regularly, have a thread
that blocks for a single fence using a separate shared
context, then uses eventfd to wake up the main thread
when something happens.
Inside the guest, glmark2 typicially runs twice as fast with the thread
sync. Although in general, the performances seems to be about +30%. The
benefits is mostly for CPU-bounds tasks (when main the thread hits 100%)
A naive perf stat of the vtest renderer with glmark2 "build" test with a
fixed number of frames (500) results in the following stats data:
(do not value timing related informations, since the renderer is ran and
stopped manually)

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.
we don't need the accessor methods in virgl so far, only
the description tables, so drop all the extra stuff for now.
this introduces the python from mesa to generate our cut down
table
