Looks like it may be more complicated than it seems because we don't
have such an array internally.  What we have is an array of
`gnutls_cert's, each of which contains both the raw certificate and the
parsed certificate (see `session->internals.selected_cert_list').

Thus, to provide a (null-terminated) array of raw certificates in
`gnutls_certificate_get_ours ()', we'd need to allocate that array or
ask users for storage.

Or we could change the `gnutls_cert' structure so that it no longer
includes `raw' and store the raw certificates elsewhere.  But that would
certainly have unforeseen implications on the rest of the code...  ;-)

I'm a bit busy, too, so I probably won't investigate it any further ATM.

Thanks,
Ludovic.
