s4: Major rework of the LDB/SAMDB/IDMAP python bindings
- Centralise the lookups for the default domain (root) in the call "domain_dn" - Reduce the LDB connections attempts ("connect" calls) from three to one - tools should load faster - Make the LDB connection init more like the "ldb_wrap_connection" call - Load the right UTF8 casefolder which fixes up problems with special characters (discovered by me: e.g. small "Umlaute" (ä, ö, ü, ...) in the DN weren't upcased - so records "seemed" lost in TDB)
