shivers 00af71f77d There was a weird bug in the GC system. The image-writing code causes a
GC to assemble a compacted heap image in newspace which it then writes out
to disk. Then the VM calls ABORT-GC to cancel the GC operation, which scans
the current space, fixing up the "broken hearts" -- restoring word 1 of
each structure that got clobbered with a forwarding pointer.

Unfortunately, someone (possibly myself) had inserted a post_gc_fdports() call
into the VM between the gc and the abort. This procedure updates a C vector of
Scheme values (fdports[]) by following forwarding pointers -- BUT -- in this
instance we didn't really want to break hearts, and the abort-gc code didn't
know about the fdports[] vector, so it couldn't undo the effects. This caused
the fdports[] vec to point into hyperspace after the image dump, and *that*
meant on the next GC, all the live ports were considered dead. Oops.

The fix was to remove this bogus call. The post_gc_fdports() proc is now
called only after a *real* GC.

shivers 7d810091d8 Commented out module-loading print statements that were vestigial debugging
cruft.

shivers 7c90829350 Added a whole bunch of .h files describing the module structure of the C
files. These files mostly mediate between the C source (export) and
the corresponding C stub files (import) generated by the Scheme files
calling the C routines.

This provided much better argument type checking that before; lots of
small bugs were caught.

Also added const keywords wherever I could find a reasonable place
to improve error detection and efficiency.

Tuned up the makefile to reflect all of this structure. Its dependencies
were pretty out-of-date as it was. It could probably use further work.

shivers 3e52c5100b - Fixed errno-error calls to include the syscall's args. This should greatly
improve the quality of the error messages.

- Fixed file-match so that if a filter procedure raises an error condition,
  it is caught and treated as a match failure (as if the procedure returned
  #f). This means you no longer get blown out of the water by
    (file-match "." #f file-directory?)
  if the cwd contains a dangling symlink, for example.

- Added set-file-times (utime).

- Caught a bug in an unused arm of the define-errno-syscall macros (rest arg
  case).

- Perhaps one or two other minor tweaks.
