LibSQL+SQLServer+SQLStudio+sql: Use proper types for SQL IPC and IDs

Browse source 
When storing IDs and sending values over IPC, this changes SQLServer to:

1. Stop using -1 as a nominal "bad" ID. Store the IDs as unsigned, and
   use Optional in the one place that the IPC needs to indicate an ID
   was not allocated.

2. Let LibIPC encode/decode enumerations (SQLErrorCode) on our behalf.

3. Use size_t for array sizes.
