* MAKE-$SPACE ( size #frames -- addr )

Allocate and initialize a string space with size bytes available for
the string buffer including the string stack, and with a string frame
stack for frame description entries holding up to #frames. The size is
rounded up to cell alignment, and the buffer begins and ends with cell
alignment. Return addr, the address of the string space. The standard
word FREE with addr as input can be used to release the space.
