configmanager: Allow referencing previously-set options in the config file

mod_user_account_management: Clear pending deletion if account re-enabled

mod_saslauth: Fire event per SASL step This matches the behaviour of the newer mod_sasl2 implementation. It allows plugins to observe (and potentially, with caution, modify) the SASL exchange.

util.jsonschema: Return basic structured validation response

mod_c2s: Make c2s_timeout timer reachable to allow access from other modules E.g. the timeout could be extended under certain conditions.

tools: Add a tool for comparing DOAP to the latest XEP versions Needs wget, awk, sed and xml2

mod_s2s: Close connection on smacks timeout This merges the mod_s2s_smacks_timeout behavior from prosody-modules This event is fired by mod_smacks when the connection has not responded to an ack-request for a period of time defaulting to 30 seconds, indicating that the connection has become stuck or non-responsive. Closing it prevents routing further messages via this connection and frees resources. A stuck connection may otherwise remain until for a time determined by the OS TCP subsystem, which can be quite long.

mod_saslauth: Fire event at start of authentication attempt As extension point for rate limiting and similar checks, so they can hook a single event instead of <{sasl1}auth> or stream features, which might not be fired in case of SASL2 or e.g. HTTP based login.

net.http.server: Fix whitespace-ignoring syntax
