crypto: MAC nif unifying HMAC, CMAC and POLY1305

into one nif using the EVP_DigestSign interface. This
enables acceleration if available in lower layers, that is,
in cryptolib and lower.

However, for older cryptolibs the old HMAC and CMAC low-level
interfaces are used, but moved from hmac.c and cmac.c into
mac.c.
