* Some source code cleaning

- Fixed the badly worded messages during mapserver startup
- Cleaned up socket config reading
- Split resolve_hostbyname() into 2 separate functions for clarity
- Moved the probably obsolete LOWER/UPPER macros to db.c (TODO: remove)
- Moved the badly placed compare_item() function to storage.c (see r779)
