        src/common/lib/libprop: prop_dictionary.c prop_number.c prop_object.c
            prop_object_impl.h

Log Message:
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.
