Security fix

OSS-Fuzz 531780528: Stop resolving DNS during URI/GENA callback parsing. parse_hostport() called getaddrinfo() synchronously on any non-literal-IP host, and parse_uri() runs directly on untrusted input in two places: the HTTP request-line parser (embedded miniserver) and GENA SUBSCRIBE callback-URL parsing. A remote, unauthenticated peer could block a worker thread on DNS resolution (CWE-400). parse_uri()/parse_hostport() no longer perform DNS resolution; the new resolve_hostport() defers it to legitimate outbound-connection points. GENA SUBSCRIBE callback URLs now require a literal IP outright, closing a DNS-rebinding gap in the CVE-2020-12695 (CallStranger) same-subnet check as well.

Pushed directly to main (commits 5dba8070, 8b016a29, 0a03336b) ahead of this release. A GHSA advisory will follow.
