continuations are vm procedures
* libguile/vm-i-system.c (continuation-call): New op, like subr-call or
foreign-call, but for continuations.
* libguile/continuations.h: Add scm_i_continuation_call internal
declaration.
(SCM_CONTINUATIONP): Reimplement in terms of
SCM_PROGRAM_IS_CONTINUATION.
(scm_tc16_continuation, SCM_CONTREGS, SCM_CONTINUATION_LENGTH)
(SCM_SET_CONTINUATION_LENGTH, SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE)
(SCM_CONTINUATION_ROOT, SCM_DFRAME): Remove these from the exposed
API.
(scm_i_continuation_to_frame): New internal declaration.
* libguile/continuations.c
* libguile/continuations.c: Add trickery like in foreign.c, smob.c, and
gsubr.c, so that we can make procedural trampolines for continuations.
(scm_i_continuation_to_frame): New internal function, from stacks.c.
* libguile/programs.h (SCM_F_PROGRAM_IS_CONTINUATION)
(SCM_PROGRAM_IS_CONTINUATION): Add a flag for programs that are
continuations. Probably should add flags for the other trampoline
types too.
* libguile/programs.c (scm_i_program_print): Print continuations as
before.
* libguile/stacks.c (scm_stack_id, scm_make_stack): Use
scm_i_continuation_to_frame in the continuation case.
