obsfate: makes successorsetverb takes the markers as argument

Right now, successorsetverb only needs successors to compute the verb. But we
will want use additional information (effect-flags and operation) in the near
future to compute a better verb.

Add the markers parameter now so extensions (like Evolve) could wrap the
function and start experimenting around better obsfate verbs.

As successorsetverb now takes both successorset and markers parameters, rename
it to obsfateverb, successorsetandmarkersverb was too long.

Import a rules file against a 'blank' sparse profile

  $ hg debugsparse --import-rules $TESTTMP/rules_to_import

Start against an existing profile; rules *already active* should be ignored

  $ hg debugsparse --enable-profile webpage.sparse
  $ hg debugsparse --include *.py
  $ cat > $TESTTMP/rules_to_import <<EOF
  > %include base.sparse

  $ cat .hg/sparse
  %include webpage.sparse
  [include]

  $ hg debugsparse --reset
  $ rm .hg/sparse

Same tests, with -Tjson enabled to output summaries

If importing results in no new rules being added, no refresh should take place!

  $ cat > $TESTTMP/trap_sparse_refresh.py <<EOF
  > from mercurial import error, sparse
  > def extsetup(ui):
  >     def abort_refresh(*args, **kwargs):
  >         raise error.Abort('sparse._refresh called!')
  >     sparse.refreshwdir = abort_refresh
  > EOF
  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > trap_sparse_refresh=$TESTTMP/trap_sparse_refresh.py
  > EOF
  $ cat > $TESTTMP/rules_to_import <<EOF
  > [include]
  > *.py
  > EOF
  $ hg debugsparse --import-rules $TESTTMP/rules_to_import

If an exception is raised during refresh, restore the existing rules again.

  $ cat > $TESTTMP/rules_to_import <<EOF
  > [exclude]
  > *.html
  > EOF
  $ hg debugsparse --import-rules $TESTTMP/rules_to_import
  abort: sparse._refresh called!
