Ping!
I won't have access to my computer for two months starting on Wednesday, so if you still want anything to be changed before you can approve this, there's not much time for me left ^_^

Update order as discussed to first EventListeners, then NotifyEmitted, then adding the MemMgr and then MaterializationResponsibility::notifyEmitted().
This is basically the same order as in ObjectLinkingLayer now.

Finally found some time to continue looking into this...
ObjectLinkingLayer doesn't have this problem because it uses this order in ObjectLinkingLayerJITLinkContext:

Added missing check on Expected result of lookup.
Apply ugly clang-format include reordering (this is not even alphabetic, is this just about editing distance to the containing file name?).

I would also prefer to provide a patch set to have sensibly grouped changes like with git.

Sure, the Windows specific changes work fine on Windows.

Fixed some too long lines
