Subject: 
         [PATCH] Parametrical options support for Samba 3.0

Greetings!

Attached patch makes possible arbitrary options to be specified in
smb.conf and later queried from VFS modules (and other places)
without problems. Below such options are called 'parametrical options'.

Patch introduces new notation to smb.conf option's language, as discussed
today with Tridgell on @samba-technical:

        TYPE: OPTION = VALUE

Colon sign is important here, it is what distinguishes parametrical
options from ones hardcoded in param/loadparm.c.

TYPE is 'option domain', OPTION is option name itself.

In order to access values of parametrical options, lp_parm_string()
function was implemented:

char *lp_parm_string(const char *servicename, const char *type, const char
*option);

This function accepts service name, type and option name, and returns
value of option or NULL if this option is underfined. Service name can be
NULL, resulting in search in 'global' section only.

If option does not exist in specified service, 'global' section is
scanned. This allows propagation of globally specified options to all
services and later overloading of the option in some services.

Caution: 'TYPE: OPTION' combination is case sensitive.

So far, testparm is able to handle parametrical options, while SWAT
can't. Thus, everyone familiar with SWAT internals is welcomed to add
parametrical options support.
