Fixup HMAC key size sanity checking.

Key lengths should be checked against the output size of the hashing
algorithm (instead of block size, which was used previously).

Provide a custom HMAC implementation

Provide a building block towards re-implementing the HOTP/TOTP
algorithms without using oath-toolkit: see issue #9.

The hmac::compute function trades simplicity (having to pre-allocate
a scratch buffer) for avoding accidental leaks of key material
(security).

This particular trade-off will help with resolving issue #6.
