Log:
[CSRSRV]
- Do not associate the newly created wait block to the waiting thread (in CsrInitializeWait) in case this one is going to terminate, but do it instead in CsrCreateWait, where the check actually takes place.
- Avoid PPORT_MESSAGE casts.
- Fix a list insertion problem in CsrMoveSatisfiedWait.
- Fix some descriptions / comments.
