[CONSRV]
- Start to implement waiting threads notifications. They can be notified by:
  * the required action (screen displaying lock/unlock, presence of new characters in the input buffer),
  * the fact that the application terminates,
  * we close a (input) handle.
  TODO: When we notify them by calling CsrNotifyWait, they are not dereferenced automatically, but they can be
  by calling a dedicated CSR function. We need to know where it is the best to dereference them.
- Correct a bug introduced in revision r58191, which broke console input mode changes (in SrvSetConsoleMode and SrvGetConsoleMode).
