f16a8b3629 Merge improvements from scheme.c.

88d5827d32 Fix typo in make_port. 
Hash tables only depend on the location of keys if they are hashed by address.
Port objects are registered for finalization when created, and definalized when closed.
New function load handles loading a file in both cases (and calls mps_chat to ensure finalization).
Avoid calling fclose multiple times on a file handle.
Merge main loop improvements from scheme-malloc.c.

d984d32588 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.
