Currently, if there is not a match on the server name, it attempts to match the "subdomain" against the server names, and fall back to the first server defined. The server name is taken from the SERVER_NAME fastcgi' parameter, the subdomain extracted from HTTP_HOST. Keep only the SERVER_NAME matching, but still use the first server defined if there's no match. Fix the manpage documenting how matching works and drop the lie about SNI as gotwebd doesn't do TLS but just looks at what the upstream http server decided. ok stsp@

Instead of the current kill() + waitpid(WNOHANG), manage the subprocesses in a separate queue and handle SIGCHLD. A timer is installed to ensure that misbehaving subprocesses are still killed. Fixes the current "child PID 0 terminated" logs due to races with waitpid(). Issue initially reported by Josiah Frentsos. ok + tweaks stsp@

For user-facing messages it is better to avoid technical jargon like this and instead spell out what the fast-forward situation implies: that one branch is already based on another. ok jamsek

I can't assume I can blindly add one simple line.

make it opaque since it's unused outside of gotd.c. While here, drop the unused `nhelpers' field. ok/tweak stsp@

ok op, james

When users run 'got add *' the shell may pick up already versioned files and trigger errors about paths being in an unexpected status. Expand the check which previously only allowed files in added status to be double-added to cover the following status codes which are all safe to ignore: A M C m This should make bulk additions of files a bit easier in most cases. Problem reported by robert@ ok jamsek

Split part of got_worktree_merge_prepare into a new function, got_worktree_merge_write_refs, since that part doesn't make sense in the fast-forward case. ok stsp@

Previously, this command would trigger an error: got: /: bad path

fixes "proc (null)" appearing in gotd logs

in 1a0c81fb61 I've added a range check too strict for max_repos_display, as zero is allowed and means "show all the repositories".
