2cf1861e8d Improvements to clarity of weak hash table implementation: 
* TAG_SIZE was changed to TAG_COUNT in the code, so make the corresponding change in the manual.
* Avoid the "+= 2" hack: use TAG_COUNT(UNTAG_COUNT(...) + 1). Clarity is more important than speed here.
* Use obj_unused for unused hash table entries so that there can be no confusion between NULL meaning "unused" and NULL meaning "splatted by the garbage collector".
* Add references from the example code to the notes.

aaf6e8b13b New public function mps_fmt_create_k creates an object format using the keyword argument interface. 
Deprecate the format variant structures (mps_fmt_A_s, mps_fmt_B_s, mps_fmt_auto_header_s, mps_fmt_fixed_s) and the old interface (mps_fmt_create_A, mps_fmt_create_B, mps_fmt_create_auto_header, mps_fmt_create_fixed).

56b78ef7b9 Remove mps_arg from mps.h. 
Use MPS_ARGS_BEGIN etc in the Scheme example and in the manual.
Use MPS_BEGIN and MPS_END instead of BEGIN and END.
The _FIELD macros don't need to be function-like macros.
Restore TODO comments in mps.h.
Scheme example compiles with -std=c89.

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.
