-------------------------+--------------------------------
 Spinoff of #18029.

 The current behavior is to accept any of a raw port, IP address + port, or
 FQDN + port.  We also will accept oddball (historic) `inet_aton()` style
 IP addresses (raw hex) depending on if the system implements
 `getaddrinfo()` correctly or not.

 I'm inclined to leave this as is, and if users care that the HS will hit
 up the system resolver at initialization time, it should be obvious that
 they need to specify the target by IP.  That said, documentation
 clarification that an FQDN is acceptable would be ideal.

 Since both torrc and ADD_ONION style HSes call into common code, changing
 the behavior to never hit up the resolver is trivial as well.
