Subject: * gc.h: add RUBY_ prefix to debug macros. * cont.c, proc.c,
 yarvcore.c, * gc.c: define ruby_gc_debug_indent variable to debug mark/free.
 * vm.c, insnhelper.ci: rename some functions to vm_* or rb_vm_*.   move some
 functions, definitions, declarations to suitable files. * eval.c, yarvcore.h,
 eval_error.ci, insnhelper.ci: ditto.
