bottom.

Also handle the buffer state the same as mixed.

219b659320 deinterlace: force -DPREFIX on macos 
This is due to a bug in meson where it will not detect properly
the compiler if the symbols need an undercore.

552da8569b deinterlace: Enable x86 assembly with nasm on MSVC 
We need to remove x86inc.asm from the list of compiled assembly files
because it is not supposed to be compiled separately. It is directly
included by yadif.asm, and it exports no symbols.

The object file was getting ignored on all platforms except on msvc
where it was causing a linker hang when building with debugging
enabled because the object file had no debug symbols (or similar).
We've seen this before in FFmpeg too, which uses nasm:

5fce46f5ef deinterlace: Call the planar functions for the Y plane of nv12/nv21 
In some algorithms (like yadif), the Y plane has to be handled different
than the UV plane. Therefore, the planar_y functions are now called for
the Y plane, and the nv12/nv21 functions are handling only the UV/VU
planes respectively.

5468988223 deinterlace: Force renegotiation when changing mode 
Switching the deinterlacing mode on-the-fly from disabled to
auto used to work, but was broken by commit #1f21747c some
years ago.

Force re-negotiation with downstream when the mode or
fields properties are changed, otherwise deinterlace
never switches out of the passthrough mode.

f2c2560db2 deinterlace: Closed caption pass-through

fields=all), the second of the two frames will have no closed caption
data.

Also fixed memory leaks related to timecode meta pass-through.

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.
