nterr.c :

	added a structure that wraps nt errors as strings and enums, so we
	can do a smb_nt_error() function.

Makefile ntclient.c :

	added ntclient.c, broken out nt domain stuff into a separate file.
	getting fed up of compile-times and size of client.c.

	fixed the do_lsa_req_chal() function.  made it read the response,
	and return the challenge credentials received from the server.

	next stop: do_lsa_auth_2().

client.c :

	removed nt domain logon functions into a separate file.

pipenetlog.c pipentlsa.c pipesrvsvc.c smbparse.c :

	i'd broken the offsets of the RPC_HDR while trying to sort out the
	nt client code.  fixed it again.  added some robustness stuff.

util.c :

	the unistrn2() function was null-terminating the string at one
	character too many.
(This used to be commit 39cec7f698c4461aee05cfbb213879fbd486117d)
