479ffbba4a Remove author and sponsor tags; we'll deal with that some other way.
Remove $Cryb$ tags as it is likely that the code will move to git.

c658232e3e && is subject to shortcut evaluation, so the second test will not run
if the first failed.  The ultimate outcome is the same, but using &
instead ensures that, when in verbose mode, we also get output from
the second test.

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.

message of up to 2^128 bytes and therefore must use a high / low pair.

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.

8e786c5a98 Introduce t_zero (a 256-byte array of zeroes) and t_seq8 (a 256-byte array
counting up from zero).  Use them to simplify the HMAC-SHA1 test vectors.

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.
