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.

Test for `hg debugconvertbookmark` added by topics
==================================================

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

  $ cat << EOF >> $HGRCPATH
  > [ui]
  > logtemplate = [{rev}:{node|short}] {desc|firstline}\n\
  > {if(bookmarks, "  bookmark: {join(bookmarks,"\n  bookmark:")}\n")}\
  > {if(topics, "  topic: {topics}\n")}
  > EOF

  $ hg init repo
  $ cd repo
  $ echo "Hello" > a
  $ hg commit -Aqm "First commit"
  $ echo "Hello" > b

  $ hg bookmark "hellos"
  $ hg up 0 -q
  $ echo "Fix 1" > l
  $ hg commit -Aqm "Fixing first"
  $ echo "Fix 2" > m
  $ hg commit -Aqm "Fixing second"
  $ hg bookmark "secondfix"

  $ hg log -G

XXX: When we have multiple bookmarks on the same changeset, we should skip that
and do nothing. This should be fixed.
