* symbol.c: remove rb_gc_mark_symbols().

  fstrings refered by static symbols and pinned dynamic symbols
  are registerd by rb_gc_register_mark_object().
  frstring refered by dynamic symbols (not pinned symbols)
  are refered from global_symbols.dsymbol_fstr_hash (Hash object).
  Note that fstrings refered from dynamic symbols must live loger
  than symbol objects themselves because rb_gc_free_dsymbol() uses
  fstring to remove from symbol tables.
  This is why we can not mark fstrings from dynamic symbols.
  This technique reduces root objects for GC marking.
* gc.c (gc_mark_roots): ditto.
* internal.h: ditto.
