If you get a deleg_cred_handle, you should be able to use it in the same
process without further ado -- no changes needed to code calling
gss_init_sec_context(), and no gss-proxy should be needed either.

I don't think we even need GSS_C_BOTH to have been used to acquire the
acceptor credential.  What is needed is that the acceptor process have
access to the service's credentials, which clearly it must have in order
to accept.

My preference is to not make GSS_C_BOTH use a requirement on the
acceptor side.
