bfdffea0fa s3:smb2_server: convert encryption desired and required bools to flags
This adds a bitmap smbXsrv_encrpytion_flags with flags to the
smbXsrv_session_global.tdb and smbXsrv_tcon_global.tdb that we use
instead of bools for desired and required.

We need this info in the smbXsrv tdbs for smbstatus. Subsequent commits
for smbstatus will use it.

d7bb961859 s3-auth: Remove security=share (depricated since 3.6).
This patch removes security=share, which Samba implemented by matching
the per-share password provided by the client in the Tree Connect with
a selection of usernames supplied by the client, the smb.conf or
guessed from the environment.

The rationale for the removal is that for the bulk of security=share
users, we just we need a very simple way to run a 'trust the network'
Samba server, where users mark shares as guest ok.  This is still
supported, and the smb.conf options are documented at
https://wiki.samba.org/index.php/Public_Samba_Server

At the same time, this closes the door on one of the most arcane areas
of Samba authentication.

Naturally, full user-name/password authentication remain available in
security=user and above.

This includes documentation updates for username and only user, which
now only do a small amount of what they used to do.

2e69e89456 s3-auth Rename auth_serversupplied_info varaiables: server_info -> session_info
These variables, of type struct auth_serversupplied_info were poorly
named when added into 2001, and in good consistant practice, this has
extended all over the codebase in the years since.

The structure is also not ideal for it's current purpose.  Originally
intended to convey the results of the authentication modules, it
really describes all the essential attributes of a session.  This
rename will reduce the volume of a future patch to replaced these with
a struct auth_session_info, with auth_serversupplied_info confined to
the lower levels of the auth subsystem, and then eliminated.

(The new structure will be the output of create_local_token(), and the
change in struct definition will ensure that this is always run, populating
local groups and privileges).
