New description:
Add `__floordiv__` to the coercion model for `RingElement` and change
`__floordiv__` to `_floordiv_` where applicable.
This does not change any semantics of floor division, but it does fix
floor division in a few cases where coercion is involved. It also fixes
various segmentation faults like
{{{
sage: R.<x> = QQbar[]
sage: int(1) // x
...
}}}
Finally, we also implement `__itruediv__`, which was forgotten when adding
`__truediv__`.
