* libguile/continuations.c (scm_handler, c_handler)
(scm_c_with_continuation_barrier, scm_with_continuation_barrier):
Instead of calling scm_handle_by_message_noexit in the pre-unwind
handler, roll our own exception printing in the pre-unwind, and do to
exit()-on-quit in the post-unwind handler. This lets the stack unwind
at exit-time so that pending dynwinds run.
* test-suite/tests/continuations.test ("continuations"): Add a test.
* libguile/continuations.c (scm_handler, c_handler)
(scm_c_with_continuation_barrier, scm_with_continuation_barrier): Call
scm_handle_by_message_noexit in the post-unwind handler, so that
dynwinds
* test-suite/tests/continuations.test ("continuations"): Add a test.
* libguile/debug.h (scm_t_debug_frame): Remove this type, as it was
internal to the old evaluator.

(SCM_CLEAR_MACROEXP, SCM_CLEAR_TRACED_FRAME, SCM_CLEAR_ARGSREADY):
Remove macro accessors to scm_t_debug_frame.
(SCM_DEBUGOBJP, SCM_DEBUGOBJ_FRAME, SCM_SET_DEBUGOBJ_FRAME):
(scm_debug_object_p, scm_make_debugobj): Remove debugobj accessors.
(scm_i_unmemoize_expr): Remove unused declaration.
* libguile/debug.c (scm_debug_options): No more max limit on frame
sizes.
(scm_start_stack): Just call out to scm_vm_call_with_new_stack.
(scm_debug_object_p, scm_make_debugobj, scm_init_debug): No more
debugobj smob type.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_i_deprecated_last_debug_frame)
(scm_last_debug_frame): Remove deprecated debug-frame bits.
* libguile/stacks.c (scm_make_stack): Rework this function and its
dependents to only walk VM frames.
(scm_stack_id): Call out to the holder of the VM frame in question,
which should be a VM or a VM continuation, for the stack ID. Currently
this bit is stubbed out.
(scm_last_stack_frame): Removed. It seems this is mainly useful for a
debugger, and we need to rewrite the debugger to work on the Scheme
level.
* test-suite/tests/continuations.test ("continuations"): Remove test for
last-stack-frame.
* libguile/continuations.h (struct scm_t_contregs):
* libguile/continuations.c (scm_make_continuation):
(copy_stack_and_call, scm_i_with_continuation_barrier): No need to
save and restore debug frames.
* libguile/threads.h (scm_i_thread): Don't track debug frames.
(scm_i_last_debug_frame, scm_i_set_last_debug_frame): Remove macro
accessors.
* libguile/threads.c (guilify_self_1): Don't track debug frames.
* libguile/throw.c: No need to track debug frames in a jmpbuf.
* libguile/vm-engine.c (vm_engine, VM_PUSH_DEBUG_FRAMES): Don't push
debug frames.
* libguile/vm.h:
* libguile/vm.c (scm_vm_call_with_new_stack): New function. Currently
stubbed out though.
* test-suite/Makefile.am (SCM_TESTS): Add tests/keywords.test.
* test-suite/standalone/Makefile.am (test-loose-ends): New test.
* test-suite/standalone/test-loose-ends.c: New file.
* test-suite/tests/continuations.test: Three new tests.
* test-suite/tests/keywords.test: New file.

* lib.scm (with-debugging-evaluator*, with-debugging-evaluator):
New utilities.
* standalone/test-use-srfi: Use -q to avoid picking up the user's
~/.guile file.
* tests/eval.test (promises)[unmemoizing a promise]: New test.
