This series does exactly this; although I chose to reuse the code in xdiff/xutils.c instead of the new fancy next_byte/string_hash, as that code has seen more exercise already (hence I assume it has fewer bugs if any as well as its performance implications are well understood). However to do so, we need to pollute xdiff/xutils.c and include hashmap.h there (which also requires cache.h as that header has an inline function using BUG()), which I find a bit unfortunate but worth the trade off of using better tested code.
