Prevent stager deadlock if inp/out detection hangs for some reason

Even though there are calls to has_read_data(), it doesn't prevent
the put() call from blocking in a dead client or slowaris-like
situation. By moving the inp/out detection into the thread, we
allow the main handler to keep processing connections even if
a single connection hangs.
Add ReverseListenerThreaded option to prevent deadlocks

JodaZ reported that the handle_connection() sock.put call can
result in the entire reverse_tcp stager hanging if the client
stops receiving or is on a very slow link. The solution emulates
what ReverseTcpDouble already does, which is stage each connection
in a new thread. However, given that a high number of threads
can be a problem on some operating systems (*ahem* win32) this
option is not enabled by default.

We should look into thread pooling and handle_connection() timeouts
as well as event-based polling of multiple clients as alternatives,
but this option will improve the situation for our existing users.
