Log Message:
Adapt Matt Thomas's red-black tree implementation for use in proplib.  This
has a significant code size savings over <sys/tree.h>.

Also change prop_number_t to store all number objects in an r-b tree,
only ever allocating one object for any given number (we can do this
because numbers are immutable).  This results in significant run-time
memory savings.
