src/bigint.c: implement multi-precision integer.
...
To enable multi-precision integer support, you need to link
`mruby-bigint` mrbgem. The gem itself is empty but it turns on
the "bigint" support.

`MRB_USE_COMPLEX` is exclusive with `MRB_NO_FLOAT`, so we only need to
check the former.

7659b3b271
numeric.c: avoid mrb_funcall; call functions directly.

regardless of the configuration.
