- * 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.

- * will call this side the loser or losing side. This should be familiar to
- * anyone who's dealt with dreamforge or TS6 before.
- *

- *
- * If the timestamps are exactly equal, both sides merge their privilages
- * and users, as in InspIRCd 1.0 and ircd2.8. The channels have not been

- * modes from all of its users that currently exist in the channel, before
- * introducing new users into the channel which are listed in the FJOIN
- * command's parameters. This means, all modes +ohv, and privilages added
- * by modules, such as +qa. The losing side then LOWERS its timestamp value
- * of the channel to match that of the winning side, and the modes of the
- * users of the winning side are merged in with the losing side. The loser
- * then sends out a set of FMODE commands which 'confirm' that it just
- * removed all privilage modes from its existing users, which allows for
- * services packages to still work correctly without needing to know the
- * timestamping rules which InspIRCd follows. In TS6 servers this is always
- * a problem, and services packages must contain code which explicitly
- * behaves as TS6 does, removing ops from the losing side of a split where
- * neccessary within its internal records, as this state information is
- * not explicitly echoed out in that protocol.
- *
- * The winning side on the other hand will ignore all user modes from the
- * losing side, so only its own modes get applied. Life is simple for those
- * who succeed at internets. :-)
- *
- * NOTE: Unlike TS6 and dreamforge and other protocols which have SJOIN,
- * FJOIN does not contain the simple-modes such as +iklmnsp. Why not,
- * you ask? Well, quite simply because we don't need to. They'll be sent
- * after the FJOIN by FMODE, and FMODE is timestamped, so in the event
- * the losing side sends any modes for the channel which shouldnt win,
