All symbols have an fstring entry, and we initialize symbol tables
with 1000 bins. This reduces resizes during startup.

key first.
Garbage keys can be swept by lazy sweeping invoked by creating new
fstring. So that simply do:
(1) delete garbage key and return `fstr_update_callback' immediately
(2) try again `fstr_update_callback()' to create a new fstr.
This bug can be cause memory corruption, reported by

It can cause unexpected behaviour.

exposing IDs from collectable symbols.
[Bug #10014]
Now, rb_check_id() returns 0 if corresponding symbol is
pinned dynamic symbol.
There is remaining intern_cstr_without_pindown(), it can return
IDs from collectable symbols. We must be careful to use it
(only used in parse.y). I think it should be removed if
it does not have impact for performance.

add:
* STATIC_SYM2ID()
* STATIC_ID2SYM()
