New constructor make_bool avoids boilerplate.
...
Hash function takes a length so that it (1) it can support strings containing NULs; (2) it doesn't have to check for NULs so runs a bit faster; and (3) it performs OK on addresses (which often contain zero bytes).
Hash tables have hash and comparison functions.
Implement string=?, make-eqv-hashtable and make-hashtable.
