* origin/topic/robin/bit-1641:
  Fixing duplicate SSH authentication failure events.

I changed the test slightly; the output of uniq is not stable between
operating systems (on OS-X, it emits a space, on Linux it apparently
emits a tab). I removed the call to uniq - sort by itself is enough to
create a difference if there are duplicate entries.

4ad5d9073a NetControl: add catch and release event when IPs are forgotten.
This adds an event that is raised once Catch & Release ceases the
block management for an IP address because the IP has not been seen in
traffic during the watch interval.

This allows users who use their own logic on the top of catch and
release know when they will have to start re-blocking the IP if it
occurs in traffic again.

6b9abe85a7 Add error events to input framework.
This change introduces error events for Table and Event readers. Users
can now specify an event that is called when an info, warning, or error
is emitted by their input reader. This can, e.g., be used to raise
notices in case errors occur when reading an important input stream.

Example:

event error_event(desc: Input::TableDescription, msg: string, level: Reporter::Level)
	{
	...
	}

event bro_init()
	{
	Input::add_table([$source="a", $error_ev=error_event, ...]);
	}

For the moment, this converts all errors in the Asciiformatter into
warnings (to show that they are non-fatal) - the Reader itself also has
to throw an Error to show that a fatal error occurred and processing
will be abort.

It might be nicer to change this and require readers to mark fatal
errors as such when throwing them.

df5d9adfb4 Fixed insertion of nested subnets.
When inserting, existance of the given subnet is checked using exact
matching instead of longest prefix matching. Before, inserting a subnet
would have updated the subnet item, which is the longest prefix of the
inserted subnet, if present.

b28801ce95 Add unrolling separator & field name map to logging framework.
- When a log record is being "unrolled" (sub-records flattened
   out into a single record), it's now possible to choose the
   character/string to separate the outer name from the inner
   name.  This can be used to work around the problems
   with ElasticSearch 2.0 not supporting dots "." in field names.
   This value can be provided per-filter as well as a global
   default value.
 - Log fields can be renamed by providing a table per-filter
   (or a global default) to rename fields for any log writer.
   The name translation is performed after unrolling so the
   value in the field name table must match whatever is being
   used to separate field names.

   For example if the unrolling separator was set to "*":
	redef Log::default_unrolling_sep = "*";

   The field name map would need to reflect it:
	redef Log::default_field_name_map = {
		["id*orig_h"] = "src",
		["id*orig_p"] = "src_port",
		["id*resp_h"] = "dst",
		["id*resp_p"] = "dst_port",
	};

d91dd8d9a8 Fix Bro and unit tests when broker is not enabled
When Bro was compiled with broker disabled, then some Bro scripts
were referencing functions and types that were not defined.  Fixed
by adding @ifdefs to several scripts.  Removed one @ifdef because
it was causing several unit tests to fail.

Also fixed the @TEST-REQUIRES check in tests that rely on broker so
that such tests are skipped when broker is disabled.
