3010a28f07 glstereomix: Fix caps negotiation
The videoaggregator negotiation sequence changed some time
back and broke glstereomix. Instead of doing nego incorrectly
in the find_best_format() vfunc, do it directly in the
update_caps() method.

d865d9126b Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Matej Knopp <matej.knopp@gmail.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

5a74878988 glframebuffer: rewrite for a more consistent API
Facilities are given to create fbo's and attach GL memory (renderbuffers
or textures).  It also keeps track of the renderable size for use with
effective use with glViewport().

11bb4454a8 glvideomixer: fix race retrieving the GL context from the display
_get_gl_context() can be called concurrently from either propose_allocation() or
decide_allocation().  If it so happens that this happens at the same time,
the check for whether we already had a GL context was outside the lock.  Inside
the lock and loop, the first thing that happens is that we unref the current GL
context (if valid) as if there was a conflict adding it to the display.  If the
timing was unlucky, subsequent use of the GL context would be referencing an
already unreffed GL context object resulting in a critical:

g_object_ref: assertion 'object->ref_count > 0' failed

0934af6cce videoaggregator: Don't wait if input buffer is after output
If the input buffer is after the end of the output buffer, then waiting
for more data won't help. We will never get an input buffer for this point.

This fixes compositing of streams from rtspsrc.

3d0f8cfc21 tests: compositor: drop special case for valgrind timeout
The default one is 6 minutes, the test was using 5 minutes so just
resort to using the default.

For the non-valgrind test also use the default 20 secs instead of
reducing it to 6s. No real reason to set a custom value here.

86d21e9455 videoaggregator: fix caps queries to allow proper renegotiation
When caps are already negotiated it should be possible to
select formats other than the one that was negotiated. If downstream
allows alpha video caps and it has already negotiated to a non-alpha
format, caps queries should still return the alpha caps as a possible
format as caps renegotiation can happen.

Includes tests (for compositor) to check that caps queries done after
a caps has been negotiated returns complete results

f1323fb6df videoaggregator: don't do caps processing that is not overridable
Allows the subclass to completely override the chosen src caps.

This is needed as videoaggregator generally has no idea exactly
what operation is being performed.

- Adds a fixate_caps vfunc for fixation
- Merges gst_video_aggregator_update_converters() into
  gst_videoaggregator_update_src_caps() as we need some of its info
  for proper caps handling.
- Pass the downstream caps to the update_caps vfunc
