c73bb8fdc4 Disable broker message forwarding by default
Still finding it to not be foolproof enough to enable generally for all
nodes in a cluster.  Specific/advanced use-cases may still consider
enabling, possibly just for specific nodes.

5c68093bc3 Permit weird sampling rate of 0.
This change allows a weird sampling rate of 0, which completely suppresses
all notifications (previously this crashed Bro). If also fixes the sampling
threshold to work with sampling rates of 0.

31d8391af0 Fix a routing loop in control framework
A controllee now subscribes to a topic prefix based on their node ID
instead of the common control topic prefix.

1dcead93bf Add Broker::forward() function
This enables explicit forwarding of events matching a given topic
prefix.  Even if a receiving node has an event handler, it will not
be raised if the event was sent along a topic that matches a previous
call to Broker::forward().

8db042a8c2 Remove Cluster::broadcast_topic
As enabling Broker forwarding would cause routing loops with messages
sent to such a topic (one subscribed to on all nodes).

1a75ef2abd Remove "relay" family of Broker functions
Namely these are now removed:

    - Broker::relay
    - Broker::publish_and_relay
    - Cluster::relay_rr
    - Cluster::relay_hrw

The idea being that Broker may eventually implement the necessary
routing (plus load balancing) functionality.  For now, code that used
these should "manually" handle and re-publish events as needed.

82cefd23c4 Fix base/misc/version.bro version parsing
Turns out that base/misc/version.bro did not parse Bro versions
correctly in case the version is just 2.5-12 or similar. This commit
fixes this oversight and adds a few more small testcases.

620cd671ba Fix tracking of DCE-RPC context identifier mappings
This adds previously-missing support for "Alter Context"
request/response PDUs (initial patch contributed by Mark Fernandez).

Also, context ID arguments were added to dce_rpc_bind, dce_rpc_request,
and dce_rpc_response in order to properly track what endpoint/operation
a given opnum maps to.
