* include/ruby/ruby.h:
Declare few functions.
* rb_sym2id: almost same as old SYM2ID but support dynamic symbols.
* rb_id2sym: almost same as old ID2SYM but support dynamic symbols.
* rb_sym2str: almost same as `rb_id2str(SYM2ID(sym))` but not
pin down a dynamic symbol.
Declare a new struct.
* struct RSymbol: represents a dynamic symbol as object in
Ruby's heaps.
Add few macros.
* STATIC_SYM_P: check a static symbol.

* template/id.h.tmpl: use LSB of ID as a flag for determining a
static symbol, so we shift left other ruby_id_types.
* string.c: use rb_sym2str instead `rb_id2str(SYM2ID(sym))` to
avoid pinning.

to avoid pinning.
