consisting of the Pearson string hash function and the Murmur3-32 hash
function.

3ed82792fc Fix a bug that affected unterminated buffers: strlcat() would write a NUL
past the end of the buffer and return one less than the correct length.

340b3240cf Consistently use const void * for data and keys, uint8_t * for digests
and MACs, and uint8_t, uint32_t or uint64_t (as appropriate) for internal
state.  Also remove a few unnecessary casts.

5bb81214cc Instead of storing the key in the hmac_sha1_ctx so we can compute the
output pad in hmac_sha1_final(), prepare a sha1 context in advance and
discard the key as early as possible.
Inspired by Colin Percival's HMAC-SHA-256 implementation.

dffacacccf The spec says XOR here, not OR. Interestingly, it doesn't seem to
make any difference.
