Added the equivalence operator. The major index optimizations are done.
...
Notes:
1) Some optimizations will follow after more deep analysis.
2) The syntax "==" is not yet agreed on. I'd prefer it to be changed.

Small optimization of multiple OR booleans (or a constant IN predicate).
...
The idea is to use a single sparse bitmap for an index matching and hence avoid OR'ing bitmaps for every argument value.
Ported from Yaffil.

Fixed (hopefully) savepoints implementation:

New explicit pessimistic locks implementation. It is logically consistent in all TPB modes and should be very fast.
