Changeset 25638 in vbox for trunk/src/VBox/Runtime/r3/win

svn:sync-xref-src-repo-rev:

56338

Message:

iprt,pdmcritsect: Added RTSemEvent[Set|Add|Remove]Signaller so that we can validate who is signalling an event if we like and, more importantly, detect deadlocks involving event semaphores. More attempts at dealing with the races (and bugs) in the all-other-threads-blocking detection in tstRTLockValidator.cpp, adding RTThreadGetReallySleeping and RTThreadGetNativeState in the process.
