    33Add factory for accepting client connections.
    44
    5 The new XMPPC2SServerFactory is a server factory for accepting client
     5The new `XMPPC2SServerFactory` is a server factory for accepting client
    66connections. It uses `XMPPClientListenAuthenticator` to perform the
    7 steps for authentication and binding of a resource, and keeps a list
    8 of all streams.
    9 
    10 Upon loss of the connection, the service is called with `unbindResource`.
    11 Received stanzas cause the service's `onElement` to be called.
    12 
    13 The factory has a `deliverStanza` method to deliver stanzas to a particular
    14 recipient. This is used for stanzas that have different recipient addressing
    15 than the actual recipient (for presence and messages from a different (or no)
    16 resource).
     7steps for authentication and binding of a resource.
     8
     9For each connection, the factory also sets up subprotocol handlers by
     10calling `setupHandlers`. By default these are `RecipientAddressStamper`
     11and `StanzaForwarder`.
     12
     13The former makes sure that all XML stanzas received from the client
     14are stamped with a proper recipient address. The latter
     15passes stanzas on to the stream's avatar.

     3Generalize StreamManager and add ServerStreamManager.
     4
     5This generalizes `StreamManager` to `BaseStreamManager` to take the
     6common functionality and reuse it for `ServerStreamManager`. Where
     7`StreamManager` is used for initiating connections, with a factory as
     8a parameter, `ServerStreamManager` works for receiving connections. It
     9must be created in a protocol factory when a connection is established,
     10and then its `makeConnection` should be called to hook it up to the
     11`XmlStream` instance.
