Merge branch 'master' of https://github.com/worklist/hifi
Job #19700 BUG: Crash in NodeBounds::draw() fixed.

QMap and QReadWriteLock are orthogonal. Combined them into a wrapper
class called NodeToJurisdictionMap, replacing typedef. This allows us to
avoid changing method signatures wherever NodeToJurisdictionMap is used.
The lock is bound with the map and is available to all clients of the
NodeToJurisdictionMap. The lock allows multi-threaded access to the map.

Fixed compiler warning in NodeBounds.cpp regarding loss of precision
during conversion of double to GLfloat.
Merge remote-tracking branch 'upstream/master'
Made JointState transforms private.

Also changed some function names to be more descriptive.
Using "Hybrid" to describe frame with world-rotation + model-local-origin.
merge andrew/inertia into andrew/ragdoll

Conflicts:
	interface/src/avatar/Avatar.cpp
	interface/src/renderer/Model.h
remove 'fromBind' argument to getJointRotation()
unravel rotation code by giving proper names

The goal is: eliminate dependency on JointState::_combinedRotation
(which is joint-to-world) and store joint-to-model transforms instead
Ported over fixes that I made when working on delta-encoding for avatars.

start timer BEFORE moving it to another thread, because Qt otherwise will protest and the timer does not run at all - at least on windows.

this fixes restarted servers not getting properly recognized by the interface - at least on windows.
