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.

histedit should preserve topics (issue6550)

Editing commits with one topic on top of a commit with a different topic:

  $ hg init repo1
  $ cd repo1
  $ hg topic topic1
  marked working directory as topic: topic1
  $ echo 1 > A
  $ hg ci -Aqm A
  $ hg topic topic2
  $ echo 1 > B
  $ hg ci -Aqm B
  $ echo 1 > C
  $ hg ci -Aqm C
  $ hg glog
  @  2:392a64d00726 [topic2] C
  |
  o  1:8a25a1549e46 [topic2] B
  |
  o  0:c051488dac25 [topic1] A
  
Swap the order of commits B and C

  $ hg histedit s1 -q --commands - 2>&1 << EOF
  > pick 392a64d00726 C
  > pick 8a25a1549e46 B
  > EOF

Topic of B and C is preserved

  $ hg glog

Editing commits without a topic on top of a commit with a topic:

  $ hg init repo2
  $ cd repo2
  $ hg topic topic1
  marked working directory as topic: topic1
  $ echo 1 > A
  $ hg ci -Aqm A
  $ hg topic --clear
  $ echo 1 > B
  $ hg ci -Aqm B
  $ echo 1 > C
  $ hg ci -Aqm C
  $ hg glog
  @  2:c47acbb860b3 [] C
  |
  o  1:e2e2ca96a6bb [] B
  |
  o  0:c051488dac25 [topic1] A
  
Swap the order of commits B and C

  $ hg histedit s1 -q --commands - 2>&1 << EOF
  > pick c47acbb860b3 C
  > pick e2e2ca96a6bb B
  > EOF

B and C still don't have a topic

  $ hg glog

Editing commits with a topic on top of a commit without a topic:

  $ echo 1 > B
