latentprion edd223b083 Remove unnecessary componentThread.h #includes 
Since componentThread #includes boost::asio components, removing
it should improve compile times.

latentprion 5017bf5f92 Build: use piecemeal boost headers. 
Reduces compile time on a 4-core ARM Rpi5 from 1m12s wallclock
(i.e: "real") time to 0m55s; and from 4m+ "user" time to 3m8s.

hayodea eb7fe11de4 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.

hayodea ca9eae197f 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.

hayodea 08122c086c LockSet:tryAcquireOrBackoff: should take Qutex**, not Qutex*

hayodea cb8b13d0cd LockSet:release() Remove superfluous Lockvoker arg 
We decoupled unregistration from release() so we no longer need
to pass in a lockvoker to release().

hayodea d06ba8957a QtxAcqHistTracker: Implement complete algo; add depend graph 
The dependency graph class enables us to perform analysis on the
qutex acquisition history data. By generating the graph and
detecting cycles in it, we can find true gridlocks.

We use this graph analysis code to implement the algorithmically
complete version of the gridlock detector.

hayodea 71564b4d83 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.

hayodea 8123ec1227 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
lockvoker that it has stored inside of Qutex::currOwner.
