pager: add a function in compats to start pager

This will help us enabling pager when ui.pager API exists. Also we can try
plugging in the old pager API in this function and we won't have to change
anything.

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

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