New meson based plugin template

[Albin Stigö]

Hi,

I have put together a small project/plugin/element template helper:

https://github.com/ast/gst-make

It's heavily based on gstreamer-plugins-bad/tools

Very much work i progress. I hustled a bit to "ship" to see if people
actually find it useful. Feedback and pull requests are of course very
welcome.

After some iterations perhaps it could go into gst-devtools.
