mod_c2s, mod_s2s: Support for queuing callbacks to run in session thread This allows certain session-specific code that needs to run in the async context, but is itself triggered outside of that context (e.g. timers), to be queued. An example of this is the session destruction code of mod_smacks, when the hibernation timeout is reached.
