* 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.
