Closing an X display that had a VDPAU device created on it causes a crash.

Work around an identical libXext dlclose bug with the "Generic Event Extension"
by dlopening libXext.so.6 and leaving it open.

Original bug discovered and fixed by Robert Morell <rmorell@nvidia.com> in
commit 3b43955c

.

v2: Don't SKIP if creating the device fails.  Just attempting to create the
device installs the DRI2 extension that causes the problem.

If the VDPAU_DRIVER environment variable is not set, use DRI2Connect to query
the VDPAU driver name from the X server.

* Add a --with-module-dir configure parameter.

* Pass the moduledir into the wrapper.  Use it to construct the path to search
  for drivers.  Require drivers to end in a ".1" version, in case we ever want
  to rev. the interface between the wrapper and the drivers.

* If no driver is found in the new module dir, look for one in the default
  search paths.  This is intended to find libvdpau_nvidia.so for drivers that
  predate the change to move it, and can be removed in the future.

* Stash the moduledir into vdpau.pc.  Drivers can find this with
  `pkg-config --variable=moduledir vdpau`.

* Add a version to libvdpau_trace.so in case the interface between it and
  libvdpau.so ever changes.

* Install libvdpau_trace.so.1 to moduledir instead of libdir.

Detect when doxygen, dot, and pdflatex are installed.  When they are, enable
documentation.  Add --enable-documentation and --disable-documentation to
override the autodetection.  Install the docs to the configured docdir (usually
$prefix/share/doc/libvdpau).

Steal the XORG_CHANGELOG macro from X.Org and stash it in acinclude.m4.
