guile/libguile/gsubr.c
Andy Wingo 52fd9639fd foreign.h presents a more pointer-centric interface 
* libguile/foreign.c:
* libguile/foreign.h: Rework interface to be more pointer-centric.
  Details are:
  (SCM_FOREIGN_TYPE_STRUCT, SCM_FOREIGN_TYPE_POINTER): Removed; now the
  pointer in a foreign is first-class. If it points to a native type
  like uint32, then it still has a tag; but if it points to something
  else, like a struct or a pointer or something, then its type is VOID
  (i.e., void*).
  (SCM_FOREIGN_POINTER): Rename from SCM_FOREIGN_OBJECT.
  (SCM_FOREIGN_VALUE_REF, SCM_FOREIGN_VALUE_SET): Rename from
  SCM_FOREIGN_OBJECT_REF and SCM_FOREIGN_OBJECT_SET, to indicate that
  they only work with value types.
  (SCM_FOREIGN_HAS_FINALIZER): Reserve a bit to indicate if the foreign
  pointer in question has a finalizer registered.
  (SCM_FOREIGN_LEN): For void* pointers, optionally store the length in
  bytes of the associated memory region.
  (SCM_FOREIGN_VALUE_P): Rename from SCM_FOREIGN_SIMPLE_P.
  (SCM_VALIDATE_FOREIGN_VALUE): Rename from SCM_VALIDATE_FOREIGN_SIMPLE.
  (scm_take_foreign_pointer): Rename from scm_c_take_foreign. Remove
  scm_c_from_foreign.
  (scm_foreign_type): New accessor.
  (scm_foreign_ref, scm_foreign_set_x): Take some optional args, used
  when dereferencing void pointers.

* libguile/dynl.h:
* libguile/dynl.c (scm_dynamic_pointer): New function, used by
  scm_dynamic_func. Adapt code to foreign.h changes.

* libguile/goops.c (scm_enable_primitive_generic_x)
  (scm_set_primitive_generic_x): Use the SCM_SET_SUBR_GENERIC macro.

* libguile/gsubr.c (create_gsubr): Adapt to API change.
* libguile/gsubr.h (SCM_SUBRF, SCM_SUBR_GENERIC): Store the pointer
  directly, not indirected.

* libguile/snarf.h (SCM_DEFINE, SCM_IMMUTABLE_FOREIGN): Store subr
  pointers directly. Adapt to SCM_FOREIGN_TYPE_VOID change.

* libguile/vm-i-system.c (subr-call): Access the void* directly.

/* There's a maximum of 10 args, so the number of possible combinations is:
(REQ-OPT-REST)
for 0 args: 1 (000) (1 + 0)
for 1 arg: 3 (100, 010, 001) (2 + 1)
for 2 args: 5 (200, 110, 020, 101, 011) (3 + 2)
for 3 args: 7 (300, 210, 120, 030, 201, 111, 021) (4 + 3)

and the index at which N args starts:
for 0 args: 0
for 1 args: 1
for 2 args: 4
for 3 args: 9
for N args: N^2
One can prove this:
(1 + 3 + 5 + ... + (2N+1))
= ((2N+1)+1)/2 * (N+1)
= 2(N+1)/2 * (N+1)
= (N+1)^2
Thus the total sum is 11^2 = 121. Let's just generate all of them as
read-only data.
