[SMB3] Fixes and Security Upgrade for CIFS client

[Steve French]

Please pull the following changes since commit
026d15f6b9878794fae1f794cae881ccd65052e5:

Most important among these is the upgrade of the default dialect to
SMB3.0 in order to improve security. With the move to SMB3, setacl
support for SMB3 was also added (it had been allowed only for cifs)
as well as a bug fix for stable.
