Topic filter implemented

The filter is build into libxs rather than being a plug-in.
It's ID is XS_FILTER_TOPIC.

The filter assumed that the messages are text-based and consider
binary 0 to be a delimiter separating message topic from the message
body. Use of the delimiter is not mandatory though. If binary zero
is not present, whole message is used for matching.

The topic is separated into elements using dots, e.g.
"animals.dogs.fluffy".

Subscriptions match individual elements. Each element can be matched
by either literal string or a wildcard (*), for example:
"animals.*.fluffy" matches all animals called Fluffy irrsepctive
of whether they are dogs, cats or whatever.
