493989efb7 Merge improvements from scheme.c. 
TAG_COUNT is a better name than TAG_LENGTH.
Handle splat correctly even if no dependent object.

248fc6690b 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.

44b734b3a0 Separate the interactive and non-interactive loops for clarity. 
New function "load" loads a file; call this in the non-interactive case.
Fix bug: close file handle after loading (if no error).

700291e07c 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.

99bca8b5e2 Amc can't omit the guard "segrankset(seg) != ranksetempty" for calling segsetgrey, because amcz uses segments with an empty rank set. 
It's OK to call SegSetGrey on a segment with an empty rank set so long as you are not actually setting it to be grey for any traces, so correct the AVER accordingly.
