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*
No idea how this error survived in here for so long.

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 46686db07e SerializedAsyncContin: LockSet should take Qutex, not SpinLock
Apparently this error was here the whole time and it flew under
the radar.

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.

hayodea 2a60fdd9df Qutex: currOwner should use registered sh_ptr to Lockvoker
This ensures that the Lockvoker object we access from currOwner
remains valid past the lifetime of the Lockvoker object that
gets copied and invoked by boost::asio

hayodea 20d568a063 DevMgr: Call attachAll*FromKnownListReq in DeviceReattacher
Well, I guess now we have auto-reattaching devices.

hayodea bd52e49ba3 DevMgr: Add attachAllUnattachedDevicesFromKnownListReq
This function is the backbone for the DeviceReattacher daemon. It
assembles a list of all DA specs which are known to Mrntt, but which
haven't been successfully attached as yet, and attempts to attach
them.

hayodea 93103aa8d4 DevMgr: Add DeviceReattacher daemon plumbing
This is the plumbing for a periodic polling thread that tries
to reattach DA specs that failed to attach in the startup phase.

hayodea c0798d1bdb DevMgr: detachAll only detaches from attachedDeviceRoles
We no longer try to detach from the collection of specs. We
detach from the collection of attachedDeviceRoles. This means
our cleanup sequence no longer tries to clean up things that were
never set up to begin with.

hayodea e45a9ee5d1 DAP.yy: use cmdlineDASpecs; DevMgr: add attachAllUnattachedDevicesFromCmdlineReq
This method wraps around attachAllUnattachedDevicesFromReq and supplies
it with a sh_ptr<> collection of all DASpecs parsed by the DAP parser
from the cmdline.

The initialization sequence now correctly initializes all DAP specs
given on the cmdline again.
