Proposal to remove confusing "security XX mask" parameters for 4.0.0

>From my stand point, these options are more confusing than helpful. Users
coming from Samba 3 often try to specify these options AND try to use the
'Windows security settings'. Just last week a user had issues related to
setting these and not getting the outcome they expected. I had them remove
everything from the share definition except the path and 'read only = no'
options and set it though windows and they were  quite pleased when things
worked as expected. In my opinion these options were put in an old system
to make up for the things it lacked (at the time), and it would show
progression to remove them and make it work for "todays" systems. Please
don't misunderstand me these were great with Samba 3, but from a users
standpoint its MUCH easier to use ACL's.
