cmdutil: introduce "getcommiteditor()" to simplify code paths to choose editor

"getcommiteditor()" can simplify code paths to choose commit editor
according to '--edit' option as below:

    before:
        editor = cmdutil.commiteditor # or editor = None/False
        if opts.get('edit'):
            editor = cmdutil.commitforceeditor

    after:
        editor = cmdutil.getcommiteditor(**opts)

"getcommiteditor()" accepts option arguments not in "opts" style but
in "**opts" style, because some code paths want to invoke it with just
explicit "edit=True" argument (building dictionary is redundant).

Test changesets filtering during exchanges (some tests are still in
test-obsolete.t)

  $ cat > obs.py << EOF
  > import mercurial.obsolete
  > mercurial.obsolete._enabled = True
  > EOF
  $ echo '[extensions]' >> $HGRCPATH
  $ echo "obs=${TESTTMP}/obs.py" >> $HGRCPATH

Push does not corrupt remote
----------------------------

Create a DAG where a changeset reuses a revision from a file first used in an
extinct changeset.

  $ hg init local
  $ cd local
  $ echo 'base' > base
  $ hg commit -Am base
  adding base
  $ echo 'A' > A
  $ hg commit -Am A
  adding A
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg revert -ar 1
  adding A
  $ hg commit -Am "A'"
  created new head
  $ hg log -G --template='{desc} {node}'

Push it. The bundle should not refer to the extinct changeset.

  $ hg push ../other

Adding a changeset going extinct locally
------------------------------------------

Pull a changeset that will immediatly goes extinct (because you already have a
marker to obsolete him)
(test resolution of issue3788)

  $ hg phase --draft --force f89bcc95eba5
  $ hg phase -R ../other --draft --force f89bcc95eba5
  $ hg commit --amend -m "A''"
  $ hg --hidden --config extensions.mq= strip  --no-backup f89bcc95eba5
  $ hg pull ../other

  (run 'hg heads' to see heads, 'hg merge' to merge)

check that bundle is not affected

  $ hg bundle --hidden --rev f89bcc95eba5 --base "f89bcc95eba5^" ../f89bcc95eba5.hg

  $ hg --hidden --config extensions.mq= strip --no-backup f89bcc95eba5
