- added "netbios name" option in smb.conf to make controlling the name

that samba uses possible

- added "socket address" option to allow virtual SMB servers (on
systems with IP aliasing line Linux)

- disabled FAST_SHARE_MODES by default in Linux as older Linux boxes
can't do shared writeable mappings. We really need autoconf ...

- added new option types in loadparm so a string type can be specified
ot be uppercase only, this is used for the workgroup and netbios name
options

- auto-create the lock directory if it doesn't exist in shared mem
startup

- get rid of announce_backup()

- change a few comments in nmbd code

- rewrote the chaining code completely. Hopefully it will handle any
depth chains now.

- added LPRng support
