[CSRSRV]

[CSRSRV]
- Correct a misspelling 'CsrThreadAltertable' -> 'CsrThreadAlertable'.
- Introduce CSR_REPLY_CODEs instead of using hardcoded values, and use them with CSR_API_ROUTINE-type functions. They correspond to which decision CSRSRV should take after a server function is called: answer to the client or not, and perform according tasks.

[BASESRV]
Use CSR_REPLY_CODEs.
