and rename them with "nettle/gcrypt/glib" prefix.
2) introduces hash framework, including QCryptoHashDriver
and new public APIs.

Call the existing qcrypto_hash_supports method from
qcrypto_hash_bytesv instead of open-coding it again.

GLib >= 2.16 provides GChecksum API which is good enough
for md5, sha1, sha256 and sha512. Use this as a final
fallback if neither nettle or gcrypt are available. This
lets us remove the stub hash impl, and so callers can
be sure those 4 algs are always available at compile
time. They may still be disabled at runtime, so a check
for qcrypto_hash_supports() is still best practice to
report good error messages.
