drw: minor improvement to the nomatches cache
1. use `unsigned int` to store the codepoints, this avoids waste on common case where `long` is 64bits. and POSIX guarantees `int` to be at least 32bits so there's no risk of truncation. 2. since switching to `unsigned int` cuts down the memory requirement by half, double the cache size from 64 to 128. 3. instead of a linear search, use a simple hash-table for O(1) lookups.
