First `working'' Guile! Crashes in flush-all-ports' (relates to SCM_I_PORT_TABLE).

* libguile/gc.c (scm_gc_stats): Fixed so that it returns a relevant
  result instead of just `SCM_EOL'.

* libguile/ports.c: Include `assert.h'.  Don't include `malloc.h'.
  (scm_make_port_type): Use `scm_gc_realloc ()' instead of `realloc ()'.
  (scm_new_port_table_entry): Likewise.
  (scm_flush): Added an assertion on the port number.
  (scm_ports_prehistory): Use `scm_gc_malloc ()' instead of `scm_malloc ()'.
