Add some abstractions to simplify the `rbuf_but_last_n_lines()` function, which implements the "take all but the last `n` lines" functionality of the `head` program. This commit adds - `RingBuffer`, a fixed-size ring buffer, - `ZLines`, an iterator over zero-terminated "lines", - `TakeAllBut`, an iterator over all but the last `n` elements of an iterator. These three together make the implementation of `rbuf_but_last_n_lines()` concise.
