The `promisor_remote_reply()` function performs two tasks: 1. It uses filter_promisor_remote() to parse the server's "promisor-remote" advertisement and to mark accepted remotes in the repository configuration. 2. It assembles a reply string containing the accepted remote names to send back to the server. In a following commit, the fetch-pack logic will need to trigger the side effect (1) to ensure the repository state is correct, but it will not need to send a reply (2). To avoid assembling a reply string when it is not needed, let's change the signature of promisor_remote_reply(). It will now return `void` and accept a second `char **accepted_out` argument. Only if that argument is not NULL will a reply string be assembled and returned back to the caller via that argument.
