* libguile/pairs.h: Remove inline scm_cons, scm_car, scm_cdr defnitions;
this is less important now with the VM. Add a "struct scm_pair", and
make all SCM_CAR / SCM_CDR checks use it. For now it does type checking
as well.
* libguile/pairs.c (scm_cons, scm_car, scm_cdr): Implement here.
* libguile/scm.h (SCM_DEBUG_PAIR_ACCESSES): No more macro!
Gosh this was a slog
* libguile/dynstack.c (dynstack_ensure_space): Use malloc and free.
Threads have off-heap dynstacks, with manual marking.
(scm_trace_dynstack): Implement tracing.
(trace_pinned_trampoline, scm_trace_dynstack_roots): Implement tracing
for active threads.
(scm_dynstack_capture): Tag dynstacks.
* libguile/dynstack.h (scm_t_dynstack): Add a tag.
(scm_t_dynstack_winder_flags): Add SCM_F_DYNSTACK_WINDER_MANAGED.

* libguile/dynwind.c (scm_dynwind_unwind_handler_with_scm)
(scm_dynwind_rewind_handler_with_scm): These values need to be traced by
GC.
* libguile/scm.h (scm_tc16_dynstack_slice): New typecode. No need for
equality etc because it shouldn't escape to Scheme (currently).
* libguile/trace.h: Add trace decls.
* libguile/threads.c (scm_trace_thread_roots): Trace dynstacks
explicitly here, as they are off-heap.
* libguile/print.c (iprin1):
* libguile/eq.c (scm_equal_p): Add case for locales and also regexps
which we missed in the past.

* libguile/macros.c (scm_i_make_primitive_syntax_transformer):
(scm_i_primitive_syntax_transformer): Rename internal functions from
scm_i_make_primitive_macro, etc. Use new representation.
(scm_make_syntax_transformer): Update for new representation.
* libguile/continuations-internal.h: New file, for internal definitions.
* libguile/continuations.h: Move out internal definitions.

This doesn't fundamentally change how charsets are represented, but it
will eventually allow us to migrate more functionality to scheme, as the
charsets have a Scheme-legible representation. Also, and this is really
the point, give charsets their own type code, so that they can be
traced precisely.
* libguile/eq.c:
* libguile/evalext.c:
* libguile/goops.c:
* libguile/print.c:
* module/oop/goops.scm: Adjust to new tc16.
* libguile/srfi-14.h: Make private things private.

functional change.
* module/ice-9/weak-vector.scm: New implementation, same interface.
* doc/ref/api-memory.texi (Weak vectors): Default weak vector value was
documented as empty list when it was actually unspecified, but #f is
most useful, so we change documentation and code to match.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(DOT_X_FILES):
(DOT_DOC_FILES):

with deprecation stubs that call out to Scheme.

* module/system/vm/assembler.scm: Remove wvect tc7.
* libguile/scm.h (scm_tc7_thread): Give threads their own tc7.
* libguile/threads.h (struct scm_thread): Add a tag, so that struct
thread can be a SCM directly. Add a struct gc_mutator* member.
(scm_thread_handle): New inline function.
(SCM_I_IS_THREAD, SCM_I_THREAD_DATA, SCM_VALIDATE_THREAD): Update to use
tc7 instead of SMOB tags.

* module/system/base/types/internal.scm (heap-tags)
* module/system/vm/assembler.scm: (emit-thread?): Adapt to
scm_tc7_thread.
* libguile/gc-internal.h: Move init functions that take "struct
gc_stack_addr" here, so that internal Whippet uses don't cause Whippet
to be added to public headers.
* libguile/gc.c (scm_storage_prehistory): Take struct gc_stack_addr as
arg, and pass to gc_init. Return a mutator pointer.
* libguile/init.c (scm_i_init_guile): Pass mutator and stack base to GC
and thread init routines.
* libguile/threads.c (scm_trace_dynstack, scm_trace_thread)
(scm_trace_thread_mutator_roots): New infra for marking threads in terms
of Whippet API.
* libguile/threads.c (guilify_self_1): Since we don't use a separate GC
kind for threads any more, and thread marking is keyed off
gc_mutator_set_roots, we can avoid some of the gnarly synchronization.
(on_thread_exit): Arrange to gc_finish_for_thread.
(scm_i_init_thread_for_guile): Use gc_init_for_thread.
(init_main_thread, with_guile, scm_i_with_guile): Use Whippet API.

the current mutator's SCM thread object.
* libguile/trace.h: New file, to declare implementations of trace
routines.
* libguile/Makefile.am (noinst_HEADERS): Add trace.h.
* libguile/scm.h: BUILDING_LIBGUILE is not always defined. This is
signaled by -Werror=undef in code using libguile. This patch fixes
commit dc3a3a84f9
* NEWS: Update.

In https://gcc.gnu.org/wiki/Visibility, they recommend _WIN32 and
__CYGWIN__ as the test defines for dllexport.

type.

useless lists.

As the FSF advises, 'There is no legal significance to using the
three-character sequence “(C)”, but it does no harm.' It does take up
space though! For that reason, we remove it here from our C files.
