        common/lib/libprop/prop_object_impl.h: revision 1.28
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.
