Provide restricted version of MatchJournal.replay to utilize the descendants information of chunks
...
In some cases replay could 'overshoot' because the position replayed to was invalidated.
The natural way is to replay to the last descendant of such activated occurrence
and continue execution from here.

Fix incremental match insertion logic for corner case of rules of equal priority
...
Behavior was incorrect in the case of discarding rules.
Several discarding matches could appear on the same occurrence,
beacuase newer incremental matches were inserted before later one,
thus seeing their occurrence as still active and stored.

Handle journal reset for occurrences: upd their status (eg !alive). Add test for one error caused by it.
...
Occurrences which weren't yet activated (according to current journal position) can't be reactivated.
Test program is an example of such case.

Mem opt: store RuleMatchers only for principal rules between sessions. Add a test for incr processing.
...
The number of preserved matchers is around 4-10 times less.
The added test is an example of programs handled incorrectly with this opt. Fails now.

Remove unnecessary feature: StateFrameStack is no longer used.
...
StateFrameStack adds no functionality but requires too much processing.
Rename StateFrameStack -> LogicalState.
Rename ProcessingStateImpl -> ConstraintsProcessing.
Simplify occurrence's logical observer.
Introduce transient dependency on controller to LogicalState.
Keep logical state as part of session token, avoid re-initializing
all logical observers.
Make replaying of match journal independent of controller.

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.
