decouple-service-from-fd-array-index.patch

This patch removes the relationship between position in the
pollfd[] array and any meaning about the type of socket.

It also refactors the service loop so there is a per-fd
function that detects the mode of the connection and services
it accordingly.

The context wsi * array is removed and a hashtable introduced
allowing fast wsi lookup from just the fd that it is
associated with
