* id_table.c: swtich to "simple open addressing with quadratic probing"
by Yura Sokolov. For more detail measurements, see [Feature #12180]
* id_table.c: remove other algorithms to simplify the source code.

* id_table.c (hash_table_extend): should not shrink the table than
the previous capacity. [ruby-core:76534] [Bug #12614]

* id_table.h (rb_id_table_iterator_result): add dummy sentinel
member because C standard prohibits a trailing comma.

* id_table.c (list_id_table_init): When unaligned word access is
prohibited and sizeof(VALUE) is 8 (64-bit machines),
capa should always be even number for 8-byte word alignment
of the values of a table. This code assumes that sizeof(ID) is 4,
sizeof(VALUE) is 8, and xmalloc() returns 8-byte aligned memory.
This fixes bus error on 64-bit SPARC Solaris 10.

This allows us to swap in rb_id_table_memsize for st_memsize
(which takes a "const st_table *") more easily.
It also makes sense to do the same for rb_id_table_size,
too; as the table cannot be altered when accessing size.
* id_table.h (rb_id_table_size): const arg
(rb_id_table_memsize): ditto
* id_table.c (st_id_table_size): ditto

[Feature #11420]
This table only manage ID->VALUE table to reduce overhead of st.
Some functions prefixed rb_id_table_* are provided.
* id_table.c: implement rb_id_table_*.
There are several algorithms to implement it.
Now, there are roughly 4 types:
* st
* array
* hash (implemented by Yura Sokolov)
* mix of array and hash
The macro ID_TABLE_IMPL can choose implementation.
You can see detailes about them at the head of id_table.c.
At the default, I choose 34 (mix of list and hash).
This is not final decision.
Please report your suitable parameters or
your data structure.
* symbol.c: introduce rb_id_serial_t and rb_id_to_serial()
to represent ID by serial number.
* internal.h: use id_table for method tables.
* class.c, gc.c, marshal.c, vm.c, vm_method.c: ditto.
