Rename c2s_state_timeout option to state_timeout

Now, `c2s` is not doubled in the name, so `listen.c2s.c2s_state_timeout` has
become `listen.c2s.state_timeout`. Note that for websockets, I decided to keep
the prefix, so its `listen.http.handlers.mod_websockets.c2s_state_timeout`.

 * Support for [`listen.http.handlers.mod_websockets.service`] has been removed, the component connection over WebSockets did not correspond to any XEP/RFC, and neither it was properly described anywhere in the MIM documentation. It was present in the default configuration file, and **you need to delete it** from your listener configuration unless you have already done so.
 * The `max_fsm_queue` option is no longer supported for C2S listeners. It is incompatible with the new `gen_statem` state machine, and if you need to limit incoming traffic, you should use [traffic shapers](../../configuration/shaper) instead. You need to remove this option from your C2S configuration if you are using it.
 * The default value of the [`backlog`](../configuration/listen.md#listenbacklog) option for all XMPP listeners has been increased from 100 to 1024 for performance reasons.
