mod_net_multiplex: Add support for using ALPN Potentially a bit more efficient since it can jump to the selected protocol on connect instead of waiting for some data to look at. Adds a 'protocol' field to net providers for this purpose.

net.http: Set ALPN on requests Shouldn't hurt. Revert if it turns out it does. Supported in LuaSec 0.8. Should be ignored otherwise.

core.portmanager: Fix TLS context inheritance for SNI hosts (completes SNI support)

core.portmanager: Don't set the first TLS context with a cert as main context Don't think this works and it's apparently acceptable to require SNI these days.

mod_admin_telnet: Display ALPN in show_tls() if supported and available

mod_http: Log served URLs at 'info' level These are similar to the "activated service" messages from portmanager and similarily useful for the service admin to know even if they're not debugging anything.

mod_s2s: Prevent unhandled stanza handler from complaining about stream features on aborted connections I have no idea why I wrote return false in e5945fb5b71f

mod_s2s_bidi: Ignore unencrypted connections if s2s_require_encryption is set Prevents some weirdness in cases where no authentication is done

mod_s2s: Abort outgoing connections earlier when TLS requirement isn't satisfied This ensures the closure reason is accurate and not reported as an authentication or other problem

mod_s2s: Send stream errors for cert problems on outgoing connections Rationale in comment.
