b68d936ae0 Remove plugin specific static build option 
Static and dynamic plugins now have the same interface. The standard
--enable-static/--enable-shared toggle are sufficient.

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.

7af9271c85 pngdec: Wait for segment event before checking it 
The heuristic to choose between packetise or not was changed to use the
segment format. The problem is that this change is reading the segment
during the caps event handling. The segment event will only be sent
after. That prevented the decoder to go in packetize mode, and avoid
useless parsing.

63e0b29291 pngdec: change parse logic 
Right now in parse logic the signature is checked every time the parse function
is called, and the whole data is the scanned each and every time, even though the
data is scanned in the previous instance. Changing the logic such that, we skip
the bytes which are already scanned in the previous instances of parse. This
helps in avoiding multiple scan of already scanned data/signature.

e45e6382d6 pngdec: modify wrong packetized mode logic 
packetized mode is being set when framerate is being set
which is not correct. Changing the same by checking the
input segement format. If input segment is in TIME it is
Packetized, and if it is in BYTES it is not.

b32de2794b pngdec: enable libpng interlaced picture handling 
Makes libpng deinterlace Adam7 interlaced pictures
by default. It is the only interlaced format available
and if the picture isn't interlaced the code should behave
as before.

38372eb199 pngdec: add support for video/x-raw-gray formats 
pngdec can now decode gray 8- and 16-bit images without alpha channel
direct to video/x-raw-gray format. 16-bit gray images have big-endian
format, because it's native PNG endianness. Gray images with alpha
channel still converted to RGBA.
