Expose the ability to ask for index options via the library interface.
This _add_message_with_indexopts function is now a generalized form of
the older _add_message.  It lets you specify parameters and
configurations that can affect the indexing, like indexing encrypted
messages in the clear should the user choose to do so.

We also adjust the tests so that we test the extended function
returning bad values (since the non-extended function just calls the
extended one).
