Under stress, the TCP stack may return EAGAIN if there is not
space left in the sender buffer. We also enqueue any other
error.

This patch adds support for TCP as protocol to replicate
state-changes between two daemons. Note that this only
makes sense with the notrack mode.

This patch fixes a crash in the exit path for channels that
are not buffered (no CHANNEL_F_BUFFERED flag set). This fix
does not affect any existing channel in the tree.

This patch adds support for unicast UDP to the channel
infrastructure. With this patch, you can select UDP unicast to
propagate state-changes instead of multicast.

This patch reworks conntrackd to make it independent of the protocol
used to propagate state-changes. This patch adds the channel layer
abstraction, this layer allows you to add support for different
protocols like unicast UDP or TIPC.
