SSHConnectionao
    An implementation of the 'ssh-connection' service.  It is used to
    multiplex multiple channels over the single SSH connection.

    @ivar localChannelID: the next number to use as a local channel ID.
    @type localChannelID: L{int}
    @ivar channels: a L{dict} mapping a local channel ID to C{SSHChannel}
        subclasses.
    @type channels: L{dict}
    @ivar localToRemoteChannel: a L{dict} mapping a local channel ID to a
        remote channel ID.
    @type localToRemoteChannel: L{dict}
    @ivar channelsToRemoteChannel: a L{dict} mapping a C{SSHChannel} subclass
        to remote channel ID.
    @type channelsToRemoteChannel: L{dict}
    @ivar deferreds: a L{dict} mapping a local channel ID to a C{list} of
        C{Deferreds} for outstanding channel requests.  Also, the 'global'
        key stores the C{list} of pending global request C{Deferred}s.

        We get a channel from self.getChannel(), give it a local channel number

        The other side requested a channel of some sort.
        channelType is the type of channel being requested,
        windowSize is the initial size of the remote window,
        maxPacket is the largest packet we should send,
        data is any other packet data (often nothing).

        We return a subclass of L{SSHChannel}.

        By default, this dispatches to a method 'channel_channelType' with any
        non-alphanumerics in the channelType replace with _'s.  If it cannot
        find a suitable method, it returns an OPEN_UNKNOWN_CHANNEL_TYPE error.
        The method is called with arguments of windowSize, maxPacket, data.

        @type channelType:  L{bytes}
        @type windowSize:   L{int}
        @type maxPacket:    L{int}

        We got a global request.  pretty much, this is just used by the client
        to request that we forward a port from the server to the client.

            - 1: request accepted
            - 1, <data>: request accepted with request specific data
            - 0: request denied

        By default, this dispatches to a method 'global_requestType' with
        -'s in requestType replaced with _'s.  The found method is passed data.
        If this method cannot be found, this method returns 0.  Otherwise, it
        returns the return value of that method.
