c3a9d2dc64 interlace: add alternate support
Allow downstream elements to negotiate the alternate interlace mode,
splitting each input buffer in two fields, each having their own buffer.

eb914c127d interlace: rename copy_field()
It is actually copying both fields (to a single frame/buffer).

812d593c4e interlace: Store unsigned integers in unsigned integer types
And add some assertions to guard against overflows and out of bounds
reads.

c67146b27a interlace: Increment phase_index before checking if we're at the end of the phase
Incrementing it afterwards will always have to phase_index >= 1 and we
will never be at the beginning (0) of the phase again, and thus never
reset timestamp tracking accordingly.

This was broken in bea13ef43b in 2010, and
causes interlace to run into integer overflows after 2^31 frames or
about 5 hours at 29.97fps. Due to usage of wrong types for the integers
this then causes negative numbers to be used in calculations and all
calculations spectacularly fail, leading to all following buffers to
have the timestamp of the first buffer minus one nanosecond.

--enable-static/--enable-shared toggle are sufficient.

42af2d66d8 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.

e6c3446d01 interlace: Allow interlaced sink caps, do passthrough
Allow interlace to receive already interlaced content, if compatible with its
configuration. In that case, it will just do passthrough.

580a94d18b interlace: fix negotiation if filter caps are passed to query_caps
Make videotestsrc ! interlace ! $anything work again. Problem
was that upstream filter caps were passed which contained
interlace-mode=progressive, which doesn't intersect too well
with interlace's source pad template caps, leading to
not-negotiated errors.

0de362f248 interlace: Fix buffer timestamp and duration
The field rate is twice the frame rate of the src pad and so the duration of
one output buffer is src_fps_d / (2 * src_fps_n).

bea13ef43b interlace: Add pattern offset property
This property allows one to start at any point within the field pattern after
a discontinuity (whenever gst_interlace_reset () is called). Thus with the
2:3:3:2 pattern, for example, one can start at offset 2 and achieve 3:2:2:3
or offset 1 and achieve 3:3:2:2.
