There are two main external dependencies that define the feature set of this
plugin: a) the kernel and b) the VA driver
This patch tracks both dependencies, if any of them change, GStreamer will
re-inspect the plugin.
The kernel is tracked through the device files /dev/dri/card*
The VA driver is tracked through the files VA_DRIVERS_PATH/*_drv_video.so,
where VA_DRIVERS_PATH is the one defined in libva package configuration. Also,
the environment variables LIBVA_DRIVERS_PATH and LIBVA_DRIVER_NAME are tracked
since they modify the driver lookup.
Additionally, the environment variable GST_VAAPI_ALL_DRIVERS is tracked too.

Instead of rely on the automatic creation of m4 directory by aclocal, we
already control it. Later we could create our own m4 scripts in order to
unclutter configure.ac

Since the VP9 parser was added in gst-plugins-bad 1.7.1 we can remove safely
the check of the parser, as we did for the others.

Our auto-generated documentation has been a bit neglected. This patch replaces
the 'normal' gtk-doc with the one used in GStreamer, which is adapted for
plugins, elements and libraries.
This patch also re-enables documentation generation.

This is 'the' big change in gstreamer-vaapi autoconf. Now it uses the official
GStreamer common submodule.
The documentation generation has been disable temporarily since it needs a
major rework, which will be done in the following commit.

The user might enable --config-cache when calling configure script. If so, our
configuration variables will not be correctly calculated.
This patch extracts the value of our variables either from the cache or from
the operation result.

That macro is required for EGL's dynamic module loading, but since
gstreamer-vaapi doesn't creates dynamic modules, it is not required anymore.
That code in gst-libs/gst/vaapi/gstvaapidisplay_egl.c should be removed.

This patch tries to avoid branching in configure.ac using a more functional
approach in macros usage.

Add a 'x' as a prefix in string comparisons to watch out for edge cases where
the string is empty or undefined.

This patch removes almost all the parsers check since they are already in place,
with the exception of the VP9 parser, since it was merged in Gstreamer 1.7.

Right now the local JPEG parser is always compiled because the check for the
upstreamed version is broken: it looks for an non existent symbol:
GstJpegImage.
This patch changes that check for< GstJpegFrameHdr.

If the environment lacks of gstreamer development packages, this error will
be reported to the user: "gstreamer- was not found"
This is because we are using an undefined variable in the printed message. The
fix simple changes the variable for the hard-coded string "1.0".
