radicle-git init

Port over all git relevant parts of the radicle-link repository[0].
The packages that are kept are:
* git-ext
* git-ref-format
* git-trailers
* link-git
* macros
* std-ext
* test -- only the portions that test the above

The development and testing scripts are also added for local and CI
testing.
