topic: internal config option to fix hg pick behavior (issue6406)

After some consideration, hg pick was made to always use current topic (and
topic namespace), even if it's not set, in which case the resulting changeset
will not have any topic.

Previously the intended behavior was to only update topic if there was an
active topic, and not touch commit extras at all otherwise. That wasn't ideal,
since pick doesn't change active topic, and amending the just-picked commit
would unset its topic without clear user's intent to do so and to their
surprise.

Make sure touch doesn't fail to warn about divergence (issue6107)

  $ hg init touchdiv
  $ cd touchdiv
  $ echo c > c
  $ hg add c
  $ hg ci -m "added c"

  $ hg amend -m "modified c"
  $ hg prune . -q

  $ hg touch -r "desc('added c')" --hidden
  $ hg touch -r "desc('modified c')" --hidden
  [1] modified c
  reviving this changeset will create divergence unless you make a duplicate.
  (a)llow divergence or (d)uplicate the changeset?  a
  2 new content-divergent changesets

But -A allows divergence

  $ hg touch -r "desc('modified c')" --hidden -A
  1 new content-divergent changesets

  $ cd ..

Touch preserves copies

  $ hg init copies
  $ cd copies
  $ echo a > a
  $ hg ci -Aqm a
  $ hg cp a b
  $ hg ci -Aqm 'copy a to b'
  $ hg status --copies --change .
  A b
    a
  $ hg touch
  $ hg status --copies --change .
