Add allow_reentrancy parameter to ObserverList
Certain client code wants to make sure that no loop is
performed while looping to avoid unexpected behaivor.
Use this new parameter to check this condition in debug build & unit tests.
Introduced ReentrantObserverList (which is currently same as defualt)
to replace the ones that indeed have to be reentrant in a separate CL.
BUG=812109
TEST=Covered by unittests
