The SETI@home result table is about to run out of 32-bit IDs,
so we need to move to 64-bit result IDs.
This will happen to the workunit table at some point too.
I changed the server C++ code to use the "long" type for all DB IDs
(and to use appropriate conversion codes like %lu).
"long" is 64 bit on 64-bit machines.
For uniformity I did this for all tables,
even ones (like app) that will never get big.
I chose NOT to change the DB schema for now.
The new code will work with 32-bit ID fields in the DB.
As projects approach the 32-bit limit on a table they can change
its ID field, and fields that reference this table, to BIGINT.
This is likely to happen only on the result and workunit tables.
I put functions in html/ops/db_update.php
to change the IDs of these tables.
