  Log Message:
  -----------
  crypto: use /dev/[u]random as a final fallback random source

If neither gcrypt or gnutls are available to provide a
cryptographic random number generator, fallback to consuming
bytes directly from /dev/[u]random.

  -----------
  crypto: use glib as fallback for hash algorithm

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.

  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.
