We add the new Qutex acquisision history tracker that allows us to dynamically detect qutex gridlocks. We've integrated it into LockerAndInvoker::operator() in a preliminary way. We also moved all of the trace*ForGridlockOn() methods into the new QutexAcquisitionHistoryTracker singleton class. They're more appropriately located there. They're still unimplemented though.

* @brief Base class for all asynchronous continuation chain links
|
|
*
|
|
* This non-template base class provides type erasure for the continuation
|
|
* chain, allowing RTTI and dynamic casting when walking the chain.
|
|
*
|
|
* The chain walking logic can use dynamic_cast to determine the most
|
|
* derived type and perform appropriate operations.
|
|
*
|
|
* Inherits from enable_shared_from_this to allow objects to obtain a
|
|
* shared_ptr to themselves, which is useful for gridlock detection tracking.
