SONOS finally adds support for SMB2/3

[Jeremy Allison]

Release notes for their update are here:

I have a lot of SONOS kit so this is good
news (finally :-). Now, of course this is
only for SONOSv2 devices, not V1, but that's
understandable given the hardware restrictions
on the units.

The last real user of SMB1 is dead ! We can
get on with removing it from Samba :-).

Cheers,

Jeremy Allison,
Samba Team.
