Rec use meson to create dist file

[omoerbeek]

Short description

Draft as I need to double check the differences between the the autotool generated tarball and meson generated tarball.

meson dist -C yourbuilddir --formats bztar gets you the tarball.

Meson dist uses a partial checkout of the tree for subprojects (as rec is), so symlinks into the parent are dangling. There is a dist script to fix those.

To bootstrap, a few symlinks are replaced in git by actual files, as the project clause needs them before the dist script is run.

Next, after the dist dir is created, we replace the remaining symlinks into the rest of the tree by the actual files using some tar magic in the dist script.

I checked the produced tarbal can be used to build both using meson and autotools.

Dir compare shows that the meson tarball has some extra files.
autotrools show a few generated files extra that are currenlty missing in the meson tarball.
I marked them to stand out

The question is if we want to have these file sin the meson tarball as well. They would require ragel and python as abuild dep. I'd say include in tarball for ragel and nope for python generated files.

gitignore files can be excluded pretty easily: #15078
