krb5 commit: Implement cccol iterators for mslsa

[Kevin Wasserman]

The goal is for the ticket manager to be able to have 
both MSLSA and CCAPI ccaches accessible and be able
to specify either type as the 'default' ccache.  I originally
had 'switch_to' call krb5int_cc_user_set_default_name()
to allow that, but we decided that is not a good idea,
so the ticket manager now calls it explicitly, so probably
the stub is no longer necessary.  I think it is harmless in
the sense that it doesn't actually change the behavior of
kinit-ing to the mslsa ccache, though I agree it is
misleading in that it produces the expectation that you
might be able to have more than one functional mslsa
ccache.  After I verify it doesn't cause any problems,
I'll remove it.

What's the motivation for adding a switch_to stub?

If switch_to is implemented, kinit will use krb5_cc_new_unique and
krb5_cc_switch_to when getting tickets for a principal other than the
one currently in the cache.  I don't think that will work for the mslsa
type.
