keyword: support extensions using dorecord, e.g. crecord

Provide extendable keyword.recordextensions variable, so other
extensions beside hgext.record which provide the dorecord function
can cooperate with hgext.keyword like so (example from crecord):

def extsetup():
    try:
        keyword = extensions.find('keyword')
        keyword.restricted += ' crecord qcrecord'
        try:
            # use record support in keyword.py if present
            keyword.recordcommands += ' crecord qcrecord'
            keyword.recordextensions += ' crecord'
        except AttributeError:
            pass
    except KeyError:
        pass

    """create a new shared repository

    Initialize a new repository and working directory that shares its
    history with another repository.

    NOTE: using rollback or extensions that destroy/modify history
    (mq, rebase, etc.) can cause considerable confusion with shared
    clones. In particular, if two shared clones are both updated to
    the same changeset, and one of them destroys that changeset with
    rollback, the other clone will suddenly stop working: all
    operations will fail with "abort: working directory has unknown
    parent". The only known workaround is to use debugsetparents on
    the broken clone to reset it to a changeset that still exists
    (e.g. tip).
