stablesort: warm jump cache more efficiently
We no longer for a full depth iteration for all request:
- we exit early for non-merge,
- for merge, we only iterate over the exclusive area.

stablerange: use the jump information for faster iteration
Instead of doing a full iteration over the exclusive set, we compare the jump
information instead. This perform the same kind of logic than before but will
allow for much faster iteration once all the caches are in place.

stablesort: use 'depth' in mergepoint tie breaker
The parents with the most depth will is considered lower. It has a couple of
advantages.
1) the more shallow parent probably have less exclusive revision,
2) it makes Oedipus merge behave like close to the linear case,

stablesort: stop recording jump type
There are no mature user of this "jump type" data and the current implementation
is known to be buggy. So we drop the logic for now. This will make on disk

stablesort: record, cache and reuse jump
Iterating below a merge means two things:
1) iterate over the part exclusive to the higher parents,
2) iterate from the lower parents.
While iterating on the exclusive part, there will be case were we just go the
next natural parent, and case were we'll have to "jump" to another revision. If
we record all point this "jump" happens and their target, we can easily
reproduce the iteration in the future. With that information we can iterate over
the exclusive part of the merge without having to compute it entirely.
In addition we store the reason of the jump. This will help the stable range
processing later.
