(compute-getters-n-setters): Check for bad init-thunks.
* eq.c (scm_eqv_p, scm_equal_p): Turned into a primitive generics.
* goops.texi (Object Comparisons): Removed object-eqv? and
object-equal? and added eqv?, equal? and =.
* goops.scm (equal?): Provide default method for `equal?'.
(compute-getters-n-setters): Check for bad init-thunks.
* eq.c (scm_equal_p): Turned into a primitive generic.
* snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
macros.
boundness even if there is an init-thunk. (The getter can return
#<unbound> even if the slot has been set before.)
* goops.c (scm_sys_fast_slot_ref): Use SCM_SLOT instead of
scm_at_assert_bound_ref. (We don't want the unbound check. See
oop/goops/active-slot.scm.)
check of format of value returned by compute-get-n-set.
(compute-getters-n-setters): Extended format of slot
getters-n-setters to indicate position and size of slot memory
allocated in instances.
* goops.c (scm_sys_prep_layout_x): Instance allocation is now
indicated through extra fields in getters-n-setters.
(scm_add_slot): Adapted to new format of getters_n_setters slot.

goops/composite-slot.scm, goops/describe.scm, goops/dispatch.scm,
goops/old-define-method.scm, goops/save.scm, goops/util.scm: Move
module the system directives `export', `export-syntax',
`re-export' and `re-export-syntax' into the `define-module' form.
This is the recommended way of exporting bindings.
