snapshot: consider all snapshots in the parents' chains
There are no reasons to only consider full snapshot as a possible base for an
intermediate snapshot. Now that the basic principles have been set, we can
start adding more levels of snapshots.
We now consider all snapshots in the parent's chains (full or intermediate).
This creates a chain of intermediate snapshots, each smaller than the previous
one.
# Effect On The Test Repository
In the test repository, we can see a decrease in the revlog size and slightly
shorter delta chain.
However, that approach creates snapshots more frequently, increasing the risk
of ending into problematic cases in very branchy repositories (not triggered
by the test repository). The next changesets will remove that risk by adding
logic that increases deltas reuse.

==================================== Testing head checking code: Case D-3 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category D: remote head is "obs-affected" locally, but result is not part of the push TestCase 3: multi-changeset branch, split on multiple new others, only one of them is pushed .. old-state: .. .. * 2 changesets branch .. .. new-state: .. .. * 2 new branches, each superseding one changeset in the old one. .. .. expected-result: .. .. * pushing only one of the resulting branch (either of them) .. * push denied .. .. graph-summary: .. ..
