SerialAsyncContin/LockSet: add releaseQutexEarly()
...
This method allows us to avoid double-release()ing qutexes when we
want to release a qutex early. If we don't use releaseQutexEarly(),
then inside of callOriginalCb when LockSet::release is called, the
Qutex will be release()d a second time.

Lockvoker: Add registerInLockSet
...
We now create the sh_ptr to the copy of a lockvoker object in its
own supplied register method. This enables us to retain type safety
when calling make_shared, by copying the most derived version of
the lockvoker object. Then we can pass in the LockerAndInvokerBase
to the rest of the call chain.

The dependency graph class enables us to perform analysis on the

We use this graph analysis code to implement the algorithmically

Add QutexAcquisitionHistoryTracker; integrate plumbing

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.

Qutex: Deprecate old gridlock trace; add skeleton new trace

We add the skeleton of a correct history tracer for gridlocks. The
previous history tracer made the incorrect assumption that we would
find the foreign sequence's currently desired LockSet inside of the
