revset: define successors revset

This revset returns all successors, including transit nodes and the source
nodes (to be consistent with existing revsets like "ancestors").

To filter out transit nodes, use `successors(X)-obsolete()`.
To filter out divergent case, use `successors(X)-divergent()-obsolete()`.

The revset could be useful to define rebase destination, like:
`max(successors(BASE)-divergent()-obsolete())`. The `max` is to deal with
splits.

There are other implementations where `successors` returns just one level of
successors, and `allsuccessors` returns everything. I think `successors`
returning all successors by default is more user friendly. We have seen
cases in production where people use 1-level `successors` while they really
want `allsuccessors`. So it seems better to just have one single revset
returning all successors by default to avoid user errors.

In the future we might want to add `depth` keyword argument to it and for
other revsets like `ancestors` etc. Or even build some flexible indexing
syntax [1] to satisfy people having the depth limit requirement.

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
