r11468: Merge a bit more of init_sec_context from Heimdal CVS into our
DCE_STYLE modified version, and add parametric options to control
delegation.

It turns out the only remaining issue is sending delegated credentials
to a windows server, probably due to the bug lha mentions in his blog
(using the wrong key).

If I turn delgation on in smbclient, but off in smbd, I can proxy a
cifs session.

I can't wait till Heimdal 0.8, so I'll see if I can figure out the fix
myself :-)
