/*
* The server list in InspIRCd is maintained as two structures
* which hold the data in different ways. Most of the time, we
* want to very quicky obtain three pieces of information:
*
* (1) The information on a server
* (2) The information on the server we must send data through
* to actually REACH the server we're after
* (3) Potentially, the child/parent objects of this server
*
* The InspIRCd spanning protocol provides easy access to these
* by storing the data firstly in a recursive structure, where
* each item references its parent item, and a dynamic list
* of child items, and another structure which stores the items
* hashed, linearly. This means that if we want to find a server
* by name quickly, we can look it up in the hash, avoiding
* any O(n) lookups. If however, during a split or sync, we want
* to apply an operation to a server, and any of its child objects
* we can resort to recursion to walk the tree structure.
* Any socket can have one of five states at any one time.
* The LISTENER state indicates a socket which is listening
* for connections. It cannot receive data itself, only incoming
* sockets.
* The CONNECTING state indicates an outbound socket which is
* waiting to be writeable.
* The WAIT_AUTH_1 state indicates the socket is outbound and
* has successfully connected, but has not yet sent and received
* SERVER strings.
* The WAIT_AUTH_2 state indicates that the socket is inbound
* (allocated by a LISTENER) but has not yet sent and received
* SERVER strings.
* The CONNECTED state represents a fully authorized, fully
* connected server.
*/

* an object of type TreeSocket.

* the core socket engine, and we cn therefore receive activity events
* for them, just like activex objects on speed. (yes really, that
* is a technical term!) Each of these which relates to a locally
* connected server is assocated with it, by hooking it onto a
* TreeSocket class using its constructor. In this way, we can
* maintain a list of servers, some of which are directly connected,
* some of which are not.
