Michiel Visser 37da5cb3b3 LibCrypto: Correctly add length to SHA384 and SHA512 hashes ...

The SHA384 and SHA512 hashes would produce incorrect results for data
where the length % 128 was in the range 112-119. This was because the
total number of bits in the hashed values was added at the end as a
64-bit number instead of a 128-bit number. In most cases this would not
cause any issues, as this space was padded with zeroes, however in the
case that the length % 128 was 112-119, some incorrect data ended up
where this 128-bit length value was expected.

This change fixes the problems in LibTLS where some websites would
result in a DecryptError on handshake.
