Log:
[CSRSRV]: Port the CsrWait* and CsrSession* APIs from CSRSRV2. Not yet used, so no real
functional change. Fixup a few structures where needed. Initalize session support during
CSRSRV initialization. We have a pretty good hybrid now, some few more changes here and
there and we can perhaps start having the beginnings our own "basesrv.dll",
