Subject: util.c password.c :

	added automount_server() function which, if -DAUTOMOUNT is in use,
	returns the server name of the NIS auto.map entry.  otherwise,
	it returns local_server.

	added use of automount_server() for a new substitution %N for NIS
	home server.  this defaults, via automount_server(), to the same
	functionality as %L if -DAUTOMOUNT is not used.

	removed vuser->home_share.  moved code that grabbed the servername
	into the separate function automount_server().

loadparm.c :

	created "logon drive" (default of "")
	created "logon home"  (default of "\\%N\%U")
	changed default of "logon path" from NULL to "\\%N\%U\profile".

ipc.c pipenetlog.c :

	use lp_logon_drive(), lp_logon_home() and lp_logon_path() in their
	now easier-to-use form (don't have to check if *lp_logon_path() and
	manually substitute a default of \\%L\%U and do a standard_sub_basic()
	on the result, because the default automatically does this.
(This used to be commit c6c28a4c3c9010ff9d5eac4bad091189a786d5a0)
