In issue #[2836] of `libgit2`, the speed of `libgit2`'s `file://` protocol for
git operations is found to be very slow. This is further corrobarated by `rad
init` taking 13 hours to initialise the hardenedbsd [ports] repository.
There are two areas where the `heartwood` project uses `libgit2` to push using
the file protocol. The first is when via the `trasnport::local` smart transport
registration and the second is the final push to storage in the `git-remote-rad`
binary.
When both these `push` operations are changed to use the `git` binary instead,
the [ports] repository can be initialised in less than 10 minutes (nearly 100x
speed up).
This change is clearly required if `heartwood` wishes to support larger
repositories.
