topics: add a new debugconvertbookmark command to convert bookmarks to topics

This new command, aliased to debugcb converts bookmarks to topics. This command
either accept name of a bookmark using flag '-b' or '--all'.

If a bookmark is passed using '-b', the whole stack defined by that bookmark is
converted to topics. If '--all' is passed, the above thing is repeated for every
bookmark in the repository.

If the revset which we are using unable to decides revisions of the stack and
return an expty set, in that cases we are not deleting the bookmark as we are
not writing any topics of the same name as that of bookmark. Also currently if a
changeset has two bookmarks, than there is buggy behaviour. So these are known
lackings in the current implementation which will be fixed in upcoming patches.

This also adds tests for the same.

Setup
=====

  $ . "$TESTDIR/testlib/topic_setup.sh"

  $ hg init test-list
  $ cd test-list
  $ cat <<EOF >> .hg/hgrc
  > [phases]
  > publish=false
  > EOF
  $ cat <<EOF >> $HGRCPATH
  > [experimental]
  > # disable the new graph style until we drop 3.7 support
  > graphstyle.missing = |
  > # turn evolution on
  > evolution=all
  > EOF


  $ mkcommit() {
  >    echo "$1" > "$1"
  >    hg add "$1"
  >    hg ci -m "add $1"
  > }

Build some basic graph
----------------------

  $ for x in base_a base_b base_c base_d base_e ; do
  >   mkcommit $x
  > done

Add another branch with two heads

  $ hg up 'desc(base_a)'
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg branch lake
  marked working directory as branch lake
  (branches are permanent and global, did you want a bookmark?)
  $ mkcommit lake_a
  $ mkcommit lake_b
  $ hg up 'desc(lake_a)'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit lake_c
  created new head


Add some topics
---------------

A simple topic that need rebasing

  $ hg up 'desc(base_c)'
  2 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg topic baz
  $ mkcommit baz_a
  $ mkcommit baz_b

A simple topic with unstability

  $ hg up 'desc(base_d)'
  1 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg topic fuz
  $ mkcommit fuz_a
  $ mkcommit fuz_b
  $ mkcommit fuz_c
  $ hg up 'desc(fuz_a)'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg commit --amend --message 'fuz1_a'

A topic with multiple heads

  $ hg up 'desc(base_e)'
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg topic bar
  $ mkcommit bar_a
  $ mkcommit bar_b
  $ mkcommit bar_c
  $ hg up 'desc(bar_b)'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit bar_d
  $ mkcommit bar_e
  $ hg up 'desc(bar_d)'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg commit --amend --message 'bar1_d'

topic 'foo' on the multi headed branch

  $ hg up 'desc(lake_a)'
  1 files updated, 0 files merged, 7 files removed, 0 files unresolved
  $ hg topic foo
  $ mkcommit foo_a
  $ mkcommit foo_b

Actual Testing
==============

basic output

  $ hg topic
     bar
     baz
   * foo
     fuz

quiet version

  $ hg topic --quiet
  bar
  baz
  foo
  fuz

verbose

  $ hg topic --verbose
     bar (on branch: default, 5 changesets, 1 troubled, 2 heads)
     baz (on branch: default, 2 changesets, 2 behind)
   * foo (on branch: lake, 2 changesets, ambiguous destination)
     fuz (on branch: default, 3 changesets, 2 troubled, 1 behind)

Also test this situation with 'hg stack'
