Optimize rete rule matcher for dropping occurrences.
...
Introduce a reactive scheme: alpha node has "dependent" nodes which
it can invalidate transitively. Drop block initiates invalidation,
intro block actually drops the nodes.

Enhance profiler to report actual time spent at probe locations.
...

collect and calculate the actual time taken by each probe location from
the whole backtrace pool.

Refactor and redesign ReteRuleMatcher for better memory footprint.
...
Drop layer prototype, make layer mutable.
Keep nodes in a layer in a linked list with fail-safe iterator.
Introduce update queue for update blocks.
Update blocks run incrementally unless reset.
Maintain trail of introduced and dropped occurrences.
Generation iterates over nodes in the last (final) layer incrementally,
unless reset.
Introduce new test.

Minor cleanup: remove DependentRulesSpec and its usages in RulesDiff
...
for historical documentation purposes, why it was needed:
It was used for specifying and handling rules which must be simply removed
without all related incremental invalidation machinery.
Long time ago some of these dependencies weren't captured
and such "simply dependent" rules must have been handled separately.
Currently it's handled by general invalidation case.

Experimental feature: Rules segmentation.
...
The rules index is extended to observe the segment path a rule belongs to.
An occurrence is bound to the rule that activated it and thus has an
associated segment path.
Rules to be picked for activation can be selected on the basis
of matched segment path.
