r11295: new service hashing code has assumign that the service

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.
