fts-solr: Fix use-after-free crash during DNS lookup
The solr_http_client singleton outlived the user session that created
it. Its event chain held a ref on the mail_storage_service_user event,
keeping it alive after the user was freed. The SETTINGS_EVENT_INSTANCE on
that event still pointed to the already-freed settings_instance. On the
next user session, dns_lookup() walked the stale event chain and
dereferenced the dangling pointer in settings_instance_get().
Fix this by using a shorter lived HTTP client.

lib-master, master: Fix inet_listener_reuse_port=yes handling
This only works properly if the listener sockets don't change and
there is always a process listening on each of the sockets.
Now master process creates the reuse_port=yes listeners for all of the
processes at startup (up to process_limit). Each child process inherits
exactly one unique listener socket based on its assigned process index.
Since with reuse_port=yes connections are assigned to a specific socket,
processes can no longer rely on other processes picking up connections when
they are full. Instead, each process is now responsible for rejecting
connections when they reach client_limit.
