Major rewrite of the socket processing routines. Before, we launched a new thread for each incoming connection (more than 40 threads were never allowed). This could potentially be used to DoS FTL by opening and closing telnet sessions in very quick succession. The new behavior is to, instead, launch five (compile-time setting) threads per type (5 for telnet IPv4, 5 for telnet IPv6, and 5 for Unix socket communication) and let them handle incoming connections in a FIFO manner. If too many requests are sent to FTL at once, they will simply have to wait until they are accepted.

The preceeding commit changes the handling of retried queries. The logic is now changed so that distinct requests for repeated queries still get merged into a single ID/source port, but they now always trigger a re-try upstream. This effectively removes our IN-PROGRESS status so we remove the code handling this as well.

dnsmasq-v2.83 forwards multiple queries to the same destination only once and stores the other queries as duplicates. They do receive the answer later on, however, this is usually not logged (when log-queries=extra is enabled, there will be a warning about the duplicate). This commit handles such duplicates and introduces a new reply type 14 = "already forwarded"
