obscache: skip the cache entirely if not up to date
The current update code has some race condition windows around updating. But we
also ensure the cache are up to date with every transaction. So outdated cache
mean another client have been mudding the repository but things will get back
in place at the next transaction.
So we just skip using the cache when not up to date. This is not the best we
could do. But this is good enough for now.

Basic test of divergence: two divergent changesets with the same parents
With --all --any we dedupe the divergent and solve the divergence once
$ hg init test1
$ cd test1
$ mkcommits _a _b
$ hg up "desc(_a)"
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit bdivergent1
created new head
$ hg up "desc(_a)"
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit bdivergent2
created new head
$ hg prune -s "desc(bdivergent1)" "desc(_b)"
1 changesets pruned
$ hg prune -s "desc(bdivergent2)" "desc(_b)" --hidden
1 changesets pruned
2 new divergent changesets
$ hg log -G

Test divergence resolution when it yields to an empty commit (issue4950)
cdivergent2 contains the same content than cdivergent1 and they are divergent
