Bug introduced in 583fa7d1e, KX_GameObject.setActionFrame can make BL_Action::m_starttime negative. But in BL_Action::Update m_starttime is set to the current time if it's negative.
To fix it we use a boolean BL_Action::m_initializedTime to know if we should initialize the time in BL_Action::Update, it's more stable than comparing times.
Tested with bug task T45945 and T32054, with an extra patch about to fix suspend resume scene issues with actions : D1569
It fix T46381. Normally BL_Action::Update (manage action time, end, loop…) should be called the same number of times as BL_Action::UpdateIPO (update action position, scale ect… in the game object).
But the bug report shows that UpdateIPO is called one less time than Update. To fix it i revert the commit 362b25b382 and implement a mutex in BL_Action::Update.

We now keep actions around when they are finished playing so scripts can
still get access to information such as the current frame. Playing a new
action in the same layer still overwrites the previous action as before this
commit. Using an explicit KX_GameObject.stopAction() will free the memory. The
action is also freed when the KX_GameObject is freed as before.
It works similar to getActionFrame(), you have to give a layer or not (for layer 0) as the argument and it returns the name of the animation that the object is currently playing.
Example:
```
import bge
own = bge.logic.getCurrentController().owner
own.playAction("SomeAction",0,20)
print(own.getActionName())
```
>> SomeAction
Here is an example file, just open the blend file with the terminal opened
and press P, you can see how the current animation is being printed:

Updating object IPOs is not currently thread-safe since it also updates
children. This leads to problems when parents and children are both
animated. For now, updating object IPOs is done in its own loop to avoid
threading issues.
This required BL_ArmatureObject to have tighter control over armatures and poses.
Also, (Blender) armature objects are now copied instead of shared between
BL_ArmatureObjects to avoid race conditions. Also, due to the armature copy,
shape key drivers need a bit of extra fiddling to get the correct armature copy.
Initially OpenMP was used for threading, but then BLI_task was used due to being
less compiler dependent.
This commit also places time spent on skinning updates in the Animation
profiler category (was previously under the Rasterizer category).
* Blendin for Loop End works even after a negative pulse. Flipper could still use some work in this area.
* Continuous works a lot better.
* BL_Action::SetFrame() should work a little smoother.
* Adding BL_Action::Play() and BL_Action::Stop()
* Making BL_ActonManger reuse BL_Actions instead of recreating them all the time
* Making the Property play type work for the Action actuator.
