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.

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.

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.
