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.

c9536ec04b Add tests for the carry operation in sha384 and sha512, which support
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.

efd34d4cc7 In an earlier version of the API, the _init function was responsible
for allocating the context structure.  This is no longer the case, but
the _init function type was not updated to reflect this.
