We want this command to be a minimal command that just does server side
picking of commits, displaying the results on stdout for higher level
scripts to consume.
So let's simplify it:
* remove the worktree and index reading/writing,
* remove the ref (and reflog) updating,
* remove the assumptions tying us to HEAD, since (a) this is not a
rebase and (b) we want to be able to pick commits in a bare repo,
i.e. to/from branches that are not checked out and not the main
branch,
* remove unneeded includes,
* handle rebasing multiple branches by printing on stdout the update
ref commands that should be performed.
The output can be piped into `git update-ref --stdin` for the ref
updates to happen.
In the future to make it easier for users to use this command
directly maybe an option can be added to automatically pipe its output
into `git update-ref`.

For now, this is just a rename from `t/helper/test-fast-rebase.c` into
`builtin/replay.c` with minimal changes to make it build appropriately.
Let's add a stub documentation and a stub test script though.
Subsequent commits will flesh out the capabilities of the new command
and make it a more standard regular builtin.
