Fix two race conditions in proplib library. In prop_dictionary and
prop_number there was small window in which was entry left in rb tree with
reference count 0 which lead to rb tree coruption when another thread picked
this up before it was released.
Add 2 new members to the prop_object_t which are used for locking/unlocking
rb tree guard mutex.
