The fact that the lookahead buffer uses bits instead of bytes is an internal detail. Poking this through to the user API has caused a decent amount of confusion. Most buffers are provided as bytes and the inconsistency here can be surprising. The use of bytes instead of bits also makes us forward compatible in the case that we want to change the lookahead internal representation (hint segment list). Additionally, we change the configuration name to lookahead_size. This matches other configurations, such as cache_size and read_size, while also notifying the user that something important changed at compile time (by breaking).
