now that got_get_repo_commits() doesn't look at `action' we can stop fetching the commits during the rendering and bubble up the call. This yields better error messages and better replies codes on failure.

This reverts commit 0835bf10ee863d91a617270780cd79c405c6a992.

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@

On non-linux systems, as well as FreeBSD/MacOS, HOST_NAME_MAX isn't available. But it is defined a part of _SC, so we can use that.
