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.

"""
This script takes `minimumhgversion` and `testedwith` values from the first
file (e.g. hgext3rd/evolve/metadata.py) and mercurial package versions from the
second file (e.g. debian/control) and compares them using a set of rules to
find any issues.

Rules:

    - if `minimumhgversion` is a feature release, the first version from
      `testedwith` should belong to that feature release

    - if `minimumhgversion` is a bugfix release, the first version from
      `testedwith` should be the same

    - mercurial package versions (from both Depends and Build-Depends sections)
      should match `minimumhgversion`

Usage: $0 MFILE CFILE where MFILE contains extension metadata and CFILE is a
debian/control file.
