[Pdns-users] Launch single Backend multiple times

[Mario Manno]

I happily converted to powerdns 2.9.16 and tried a setup suitable for
multiple users.

Basically I want to launch the sqlite backend multiple times
(docs/html/modules.html), but there seems to be a problem with the
config file.

launch=gsqlite:user1,gsqlite:user2
gsqlite-user1-database=/var/lib/pdns/user1.db
gsqlite-user2-database=/var/lib/pdns/user2.db

This did not work, to confirm the problem i tried:

launch=gsqlite:one
gsqlite-one-database=/var/lib/pdns/db

And i get an error:
Undefined but needed argument: 'gsqliteone--basic-query' 

After adding "gsqliteone--basic-query" to the config:
Fatal error: Trying to set unexisting parameter
'gsqliteone--basic-query'

If i add "gsqlite-one-basic-query" the undefined argument error happens
again.

I took a deeper look and came up with a patch.
Looks like it wont break anything...
Now I can use multiple instances of the sqlite backend.
