obsolescence: add test for the "branch replacement" logic during push, case B7

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 changeset adds test for the improved "branch replacement" logic introduce
in an earlier commits. This tests initially lived in the evolve extensions.
Since we now have the code handling this logic in core, it make sense to have
the tests in core too.

See inline documentation for details about the test case added in this
changeset.

  (activating bookmark Z)
  $ hg bookmark

Switch back to Y for the remaining tests in this file:
  $ hg update Y

set bookmark Y using -r . but make sure that the active
bookmark is not activated

  $ hg bookmark -r . Y

list bookmarks, Y should not be active

  $ hg bookmark
     Y                         0:719295282060

now, activate Y

  $ hg up -q Y

bare update moves the active bookmark forward and clear the divergent bookmarks

  $ echo a > a
  $ hg ci -Am1
  adding a
  $ echo b >> a
  $ hg ci -Am2
  $ hg bookmark X@1 -r 1
  $ hg bookmark X@2 -r 2

test deleting .hg/bookmarks.current when explicitly updating
to a revision

  $ echo a >> b
  $ hg ci -m.
  $ hg up -q X
  $ test -f .hg/bookmarks.current

try to update to it again to make sure we don't
set and then unset it

  $ hg up -q X
  $ test -f .hg/bookmarks.current

  $ hg up -q 1
  $ test -f .hg/bookmarks.current
  [1]

when a bookmark is active, hg up -r . is
analogous to hg book -i <active bookmark>

  $ hg up -q X
  $ hg up -q .
  $ test -f .hg/bookmarks.current
  [1]

issue 4552 -- simulate a pull moving the active bookmark

  $ hg up -q X
  $ printf "Z" > .hg/bookmarks.current
  $ hg log -T '{activebookmark}\n' -r Z
  Z
  $ hg log -T '{bookmarks % "{active}\n"}' -r Z
  Z

test that updating to closed branch head also advances active bookmark

  $ hg commit --close-branch -m "closed"
  $ hg update -q ".^1"
  $ hg bookmark Y
  $ hg bookmarks
