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.

====================================
Testing head checking code: Case E-1
====================================

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 case is part of a series of tests checking this behavior.

  $ setuprepos
  creating basic server and client repo
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd client
  $ hg topic -r . Y
  switching to topic Y
  changed topic on 1 changesets to "Y"
  $ hg topic Z
  $ mkcommit B0
  active topic 'Z' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg push
  pushing to $TESTTMP/E1/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 2 changesets with 1 changes to 2 files (+1 heads)
  1 new obsolescence markers
  obsoleted 1 changesets
  $ hg up 0
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg topic Z
  marked working directory as topic: Z
