MEDIUM: threads/listeners: Make listeners thread-safe

First, we use atomic operations to update jobs/totalconn/actconn variables,
listener's nbconn variable and listener's counters. Then we add a lock on
listeners to protect access to their information. And finally, listener queues
(global and per proxy) are also protected by a lock. Here, because access to
these queues are unusal, we use the same lock for all queues instead of a global
one for the global queue and a lock per proxy for others.
