@a1phyr

Implementation of rust-lang/libs-team#367.

This mainly adds `BorrowedCursor::with_unfilled_buf`, with enables using
the unfilled part of a cursor as a `BorrowedBuf`.

Note that unlike the ACP, `BorrowedCursor::unfilled_buf` was moved to a
`From` conversion. This is more consistent with other ways of creating a
`BorrowedBuf` and hides a bit this conversion that requires unsafe code
to be used correctly.

@bors bors added S-waiting-on-bors

Status: Waiting on bors to run and complete tests. Bors will change the label on completion.
