hook: have a generic hook for transaction opening

  Run before creating a tag. Exit status 0 allows the tag to be
  created. Non-zero status will cause the tag to fail. ID of
  changeset to tag is in ``$HG_NODE``. Name of tag is in ``$HG_TAG``. Tag is
  local if ``$HG_LOCAL=1``, in repository if ``$HG_LOCAL=0``.

``pretxnchangegroup``
  Run after a changegroup has been added via push, pull or unbundle,

  before accepting them. Passed the ID of the first new changeset in
