Daniel P. Berrange 7603289712 crypto: don't open-code qcrypto_hash_supports
Call the existing qcrypto_hash_supports method from
qcrypto_hash_bytesv instead of open-coding it again.

Daniel P. Berrange 9164b89762 crypto: implement sha224, sha384, sha512 and ripemd160 hashes
Wire up the nettle and gcrypt hash backends so that they can
support the sha224, sha384, sha512 and ripemd160 hash algorithms.

Daniel P. Berrange 0c16c056a4 crypto: switch hash code to use nettle/gcrypt directly
Currently the internal hash code is using the gnutls hash APIs.
GNUTLS in turn is wrapping either nettle or gcrypt. Not only
were the GNUTLS hash APIs not added until GNUTLS 2.9.10, but
they don't expose support for all the algorithms QEMU needs
to use with LUKS.

Address this by directly wrapping nettle/gcrypt in QEMU and
avoiding GNUTLS's extra layer of indirection. This gives us
support for hash functions on a much wider range of platforms
and opens up ability to support more hash functions. It also
avoids a GNUTLS bug which would not correctly handle hashing
of large data blocks if int != size_t.
