breakage in cliconnect or thereabouts

[Ronan Waide]

Hi folks,

	* libsmb/smb_signing.c, libsmb/smbencrypt.c, Makefile.in, include/client.h, libsmb/cliconnect.c, libsmb/clientgen.c:
	Change the way we sign SMB packets, to a function pointer interface.

	The intention is to allow for NTLMSSP and kerberos signing of packets, but
	for now it's just what I call 'simple' signing. (aka SMB signing per the SNIA
	spec)

	Andrew Bartlett

some part of this change is currently stopping connections to an
NT4SP6 PDC working from Samba. I'm getting "session request to SERVER
failed (Called name not present)"

If I find the bug, I'll post further. If not, I'm sure someone else
will catch it :)

Cheers,
Waider.
