print_fields.h: rename PRINT_FIELD_UID to PRINT_FIELD_ID

As uid is not the only thing that has a special treatment of the -1
value (and, as a result, needs special care), let's rename
PRINT_FIELD_UID to PRINT_FIELD_ID and make PRINT_FIELD_UID its alias.

* print_fields.h (PRINT_FIELD_ID): Rename from PRINT_FIELD_UID.
(PRINT_FIELD_UID): Define to PRINT_FIELD_ID.
