* 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. * libguile/continuations.c (scm_i_with_continuation_barrier) * libguile/finalizers.c (queue_finalizer_async) * libguile/jit.c (compile_current_thread) * libguile/threads.c (block_self, guilify_self_2) (lock_mutex, unlock_mutex, timed_wait scm_current_thread) (scm_all_threads) * libguile/vm-engine.c (current-thread): Use scm_thread_handle instead of thread->handle. * libguile/evalext.c (scm_self_evaluating_p): * libguile/goops.c (class_thread, scm_class_of, scm_sys_goops_early_init) * libguile/print.c (iprin1) * module/language/cps/compile-bytecode.scm (compile-function) * module/oop/goops.scm (<thread>) * module/system/base/types.scm (cell->object) * 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. (scm_threads_prehistory): Take main-thread mutator and the stack base as arguments. * libguile/vm.c (scm_trace_vm): Rework in terms of Whippet API. * libguile/whippet-embedder.h (gc_trace_mutator_roots): Arrange to trace 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.
