Move debian/changelog manipulation to gbp.deb.changelog.ChangeLog.

spawn_dch switch gbp.command.wrappers.Command.

* gbp/deb/changelog.py (ChangeLog.spawn_dch): static method adapted from
  gbp.scripts.dch and converted to gbp.command_wrappers.Command.
  (add_entry): New method adapted from
  gbp.scripts.dch.add_changelog_entry.
  (add_section): New method adapted from
  gbp.scripts.dch.add_changelog_entry. Remove DebianGitRepository and
  options, this has nothing to do with changelog management.

* tests/test_Changelog.py: Test new methods.

* gbp/scripts/dch.py: Remove useless functions: system(), spawn_dch(),
  add_changelog_section() and add_changelog_entry().
  Update calls accordingly.
  (fixup_trailer): Use spawn_dch() method of ChangeLog class.
  (process_options): dch_options became a list.
  (main): Use add_section() and add_entry() methods of ChangeLog object.
  Take care of upstream version since ChangeLog.add_section() does not
  manage it anymore.
  Update exception handling, ChangeLog.spawn_dch() can raise
  "CommandExecFailed" exception.
