[PATCH] Regexp filter mechanism for browse list

[Moritz Mühlenhoff]

Hi,
we implemented a browse list filter mechanism for a customer with a very large 
environment of Windows clients and would like to propose it for inclusion into 
3.0.x.  At the customers's environment the combined amount of characters of 
the hostnames exceed 64k, running into an internal limit.  By configuring a 
regular expression in the newly introduced config  option "browse_dat filter" 
a list of hosts can be suppressed to appear in the  browse list. Thus, 
ppplying this filter allows selective hiding of unneeded hosts.

The code has been tested internally and is running in a large environment with 
several thousand hosts in production use.

regexp(3) is POSIX, so I included it unconditionally in includes.h. If you 
need additional changes or prefer a different configuration item name or  
other stylistic changes, please tell.

Cheers,
Moritz
