[PATCH] Check idmap config with testparm

you might know I work for a Distributor and fix winbind issues there every 
I see so many invalid idmap configurations, I think 70% of the configs are 
wrong or invalid. In addition our documentation for ID mapping really sucks! 
So I had a call with Marc and he started to improve it. See the User 
documentation in the Wiki.

While trying to chase down a winbindd bug the last days I read all the changes 
last year and stumbled upon Volkers nice lp_wi_scan_global_parametrics() 
function again. So I decided it is time to check the idmap config in testparm. 

So here we go ...

        idmap config * : backend = rid
        idmap config * : range = 1000000-1999999

        # Winbind domain idmap
        idmap config EARTH : backend = rid
        idmap config EARTH : range = 100000000-199999999

        idmap config MARS : backend = rid
        idmap config MARS : range = 200000000-299999999

        idmap config VENUS : backend = rid
        idmap config VENUS : range = 150000000-399999999

bin/testparm smb.conf.ads > /dev/null
Load smb config files from smb.conf.ads

ERROR: Do not use the 'rid' backend for the default backend (idmap config *)!

ERROR: The idmap range for the domain MARS overlaps with the range of VENUS
