* lisp-disunion.h:

* lisp-union.h:
* lisp.h (LISP_HASH):
Rename:
LISP_TO_VOID -> STORE_LISP_IN_VOID
VOID_TO_LISP -> GET_LISP_FROM_VOID
These new names are meant to clearly identify that the Lisp object
is the source and void the sink, and that they can't be used the
other way around -- they aren't exact opposites despite the old
names. The names are also important given the new functions
created just below. Also, clarify comments in lisp-union.h and
lisp-disunion.h about the use of the functions.
* lisp.h:
New functions STORE_VOID_IN_LISP and GET_VOID_FROM_LISP. These
are different from the above in that the source is a void *
(previously, you had to use make_opaque_ptr()).
* eval.c (restore_lisp_object):
* eval.c (record_unwind_protect_restoring_lisp_object):
* eval.c (struct restore_int):
* eval.c (restore_int):
* eval.c (record_unwind_protect_restoring_int):
* eval.c (free_pointer):
* eval.c (record_unwind_protect_freeing):
* eval.c (free_dynarr):
* eval.c (record_unwind_protect_freeing_dynarr):
* eval.c (unbind_to_1):
Use STORE_VOID_IN_LISP and GET_VOID_FROM_LISP to eliminate the
use of make_opaque_ptr() and mostly eliminate Lisp consing
entirely in the use of these various record_unwind_protect_*
functions as well as internal_bind_* (e.g. internal_bind_int).
* tests.c:
* tests.c (Ftest_store_void_in_lisp):
* tests.c (syms_of_tests):
* tests.c (vars_of_tests):
Add an C-assert-style test to test STORE_VOID_IN_LISP and
GET_VOID_FROM_LISP to make sure the same value comes back that
was put in.
