r11295: new service hashing code has assumign that the service

name stored in the array was normalized.  This was causing
records to not be deleted on a reload.  As a result,
I was getting the wrong path for various services.
Seems to be ok after this change.

Also converted canonicalize_servicename() to just
use strupper_m() rather than doing the conversion itself.
Jeremy, i think this should be ok but please check.

also cleaned up some things in the hash service code
and added debug messages for sanity purposes.
(This used to be commit e0bf0581f0aaf1505f653f2101eed61352d03da8)
