This serie adds the support of sha256_hmac and sha256_hkdf. A first version was sent several months ago just before the integration of mbedtls. This new version is based on mbedtls.
The first patch of this serie add the support of hkdf using mbedtls.
v4: - fix computation of the hmac - add more test for hmac - move sha256 common functions to sha256_common.c - some cleanup
v3: - also define sha256_hmac for legacy sha256 - add some #if to define function only when needed
