[PATCH 0/2] rust: add functions and traits for lossless integer conversions

This series introduces a copy of the lossless integer conversion
functions/traits of `nova-core` into the `kernel` crate, and makes
`nova-core` use them.

It is way overdue since its RFC [1]; recent dicussions [2] that have
suggested that it might become useful have triggered this posting.

This series is based on `rust-next`.

Changes in v1:
- Update to latest version in `nova-core`.
- Make `nova-core` use the kernel crate implementation and remove its
  own.
- Link to RFC: https://lore.kernel.org/r/[email protected]
