md4_vector(), md5_vector(), sha1_vector(), and sha256_vector() already
supported TEST_FAIL() with the OpenSSL crypto implementation, but the
same test functionality is needed for the internal crypto implementation
as well.

md->curlen cannot indicate full buffer size here since the buffered
data is processed whenever the full block size of data is available.
Avoid invalid warnings from static analyzers on memcpy() outside the
buffer length by verifying that curlen is smaller than block size.

Some crypto libraries can return in these functions (e.g., if a specific
hash function is disabled), so we better provide the caller a chance to
check whether the call failed. The return values are not yet used
anywhere, but they will be needed for future changes.
