To determine whether or not HTML data are lower than 4 bytes, use a retain
buffer rather than assuming that all should be contained in a single bucket
with the next one being EOS (if any).

When listening sockets are disabled (too many connections) and the number of
workers / active connections comes back below the limit, we need to wake up
the listener to re-enable them.

Add a new connections_above_limit() helper to determine when this applies.

It's always updated under the timeout_mutex lock, or read for logging and
scoreboard updates (not critical).

For the read cases a volatile access is enough, while removing the atomic ops
for the already protected write cases saves cycles and context switches.

Make sure the worker factor is at least one (w.r.t. WORKER_FACTOR_SCALE), and
use it to size the pollset appropriately (including K-A and lingering close
connections), in addition to the listening sockets.

Even if the listener thread is not created yet (i.e. about to be), we must
still tell it to leave, and terminate the worker queue in any case.

Make sure the compiler doesn't play games with our synchronization variables

Be more correct in comment about CONN_STATE_WRITE_COMPLETION.
We currently have/need no state to simply wait for readability on a socket,
so the previous comment was misleading. Write completion can't be used for
a simple "wait for read event and come back to process_connection hooks".
