m4 share definitions for generating Samba server smb.conf include file

Usage: m4 -DFQDN=<FQDN> /etc/local-COMMON/samba/smb-shares.conf.m4 > /etc/samba/smb-shares.conf

Depend on file /etc/local-COMMON/file-<FQDN>.m4 containing lines of
the following syntax:
	_dir(<path>,<uid>,<gid>,<modes>)dnl
	_homefiles(<os>,<mount>,<desc>,<path>[,ro])dnl
	_files(<os>,<mount>,<desc>,<path>,<uid>,<gid>,<modes>[,ro[,<group>]|,rw,<group>[,<othergroup>]])dnl
where
	<os>:		Client operating systems (mac|win|any)
	<mount>:	Mount point name
				Some mount points are handled specially:
					"netlogon" has browsing and share modes disabled
					"userprofiles" sets "force user" and pre-creates user subdirectory mode 700
					"reference" allows guests
					"homes" has read/write access and pre-creates directory mode 750
				Samba:	Use single word and max. 8 characters for WfW compatibility
	<desc>:		Mount point description. Full(?) support for iso8859-1.
	<path>:		Full path to mount point directory
	<uid>:		user name of owner of mount point directory
	<gid>:		group name of owner of mount point directory
	<modes>:	Numeric access modes of mount point directory
	ro|rw|rop|rwp:	Read-only or read/write access to mount point, and wether it should be private (not publically announced).
				Read-only access if undefined.
				_homefiles are always private.
				_homefiles are by default read-only, except "homes" (see above).
	<group>:	Primary group with access to mountpoint.
				If mount point has access "rw" then primary group has read/write access as well.
	<othergroup>:	Secondary group with readonly access

Example:

	_dir(/home/fsadmin/COMMON,fsadmin,fsadmin,755)dnl
	_files(win,netlogon,Network logon,/etc/samba/netlogon,root,root,755,ro)
	_files(win,userprofiles,User profiles,/home/fsadmin/shares_win/userprofiles,root,root,755)
	_files(win,reference,DEBIAN: Samba Linux server,/home/fsadmin/shares_win/reference)
	_homefiles(win,homes,Personal files,%H/pc))
	_homefiles(mac,,Personal files,~/mac))
	_files(win,soft,softshare,/home/fsadmin/shares_win/software,fsadmin,fsadmin,775)dnl
	_printer(win,LW,Networkprinter queue for Apple LaserWriter 16/600,/tmp,lw)

TODO:
	Support for netatalk is not yet implemented.
	<othergroup> is not yet implemented.
	Get rid of <os>: <othergroup> is now 10nth parameter which is only available in GNU m4.
	All _homefiles (including "homes") should probably have similar access default (read-only, private).
	BROKEN: Homefiles are *not* private currently :-(
