b09f478e80 Add support for Meson as alternative/parallel build system 
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.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.

13a9a7543d win32: remove outdated build cruft 
This hasn't been touched for generations, doesn't work,
and is just causing confusion. We also don't want to
maintain these files manually.

ae729440b1 videomixer: use GST_STIME_ARGS for GstClockTimeDiff

exactly this.

c1a96113db videomixer: Revert the last commit and handle resolutions differences properly

deeef84d2c videomixer: fix double unlock in segment seek segment code path 
We only want to unlock if we push an event downstream and
jump to done_unlock label afterwards. We would also unlock
in case of a segment seek and then unlock again later, and
nothing good can come of that.

(This code looks a bit dodgy anyway though, shouldn't it
also bail out with FLOW_EOS here in case of a segment seek
scenario, just without the event?)

2e120c9440 videomixer: remove dead code 
While it seems to keep a compile time selection, I traced it
to some code copied from videoconvert, where it was removed,
with the following comment:

    Also remove the high-quality I420 to BGRA fast-path as it needs
    the same fix, which causes an additional instruction, which causes
    orc to emit more than 96 variables, which then just crashes.
    This can only be fixed in orc by breaking ABI and allowing more
    variables.

Thus, I remove it here as well.

373eceef7c videomixer2: store video info with buffers to keep it in sync 
Instead the queued buffer might have an old caps while the pad
is already storing the information for a new caps. Mixing those
while handling buffers will often lead to issues

83f8ee1d41 videomixer2: Merge tag events to send them in collected. 
Otherwise there were race conditions where we would send tags
on a flushing srcpad.

We have a test for that in GES, but this should be tested
systematically with harness in the future as I believe it
is useful for exactly that kind of cases.
