samba: Change default process model to prefork

Browse Source 
Prefork is the more sensible default option now, as it better
handles a large number of client connections.

NEW FEATURES/CHANGES
====================
Default samba process model
---------------------------
The default for the --model argument passed to the samba executable has changed
from 'standard' to 'prefork'. This means a difference in the number of samba
child processes that are created to handle client connections. The previous
default would create a separate process for every LDAP or NETLOGON client
connection. For a network with a lot of persistent client connections, this
could result in significant memory overhead. Now, with the new default of
'prefork', the LDAP, NETLOGON, and KDC services will create a fixed number of
worker processes at startup and share the client connections amongst these
workers. The number of worker processes can be configured by the 'prefork
children' setting in the smb.conf (the default is 4).
