phases: leverage the collected information to record phase update
Since the lower level function already gather this information, we can directly
use it.
This comes with a small change to the test that are actually fixing them. The
previous version over-reported some phase change that did not exists. In both
case, we are force revision `1` to be secret and `0` remains draft`, the
previous code wrongly reported `0` as moving to secret while it properly
remained draft in the repository.

Regression test for support for the old repos with strange diff encoding. Apparently it used to be possible (maybe it's still possible, but we don't know how) to create commits whose diffs are encoded relative to a nullrev. This test checks that a repo with that encoding can still be read. This is what we did to produce the repo in test-revlog-diff-relative-to-nullrev.tar: - tweak the code in mercurial/revlogutils/deltas.py to produce such "trivial" deltas: > if deltainfo is None: > - deltainfo = self._fullsnapshotinfo(fh, revinfo, target_rev) > + deltainfo = self._builddeltainfo(revinfo, nullrev, fh) - hg init - echo hi > a - hg commit -Am_ - remove some cache files $ tar -xf - < "$TESTDIR"/bundles/test-revlog-diff-relative-to-nullrev.tar $ cd nullrev-diff $ hg debugdeltachain a rev p1 p2 chain# chainlen prev delta 0 -1 -1 1 2 -1 p1 1 0 -1 1 2 -1 p2 2 -1 -1 1 2 -1 p1 $ hg cat --config rhg.cat=true -r 0 a hi $ hg cat --config rhg.cat=true -r 1 a ho $ hg cat --config rhg.cat=true -r 2 a ha $ cd ..
