long share name support in Samba3

[derrell at samba.org]

I've had requests to support long share names in libsmbclient.  Unfortunately,
I don't have an XP or W2k3 server to even obtain packet traces of long share
name requests/responses.

Do we currently have any code in either Samba3 or Samba4 to support long share
names?

Thanks,

Derrell
