crypto: add support for nettle's native XTS impl (2019-10-28 16:45:07 +0100)
----------------------------------------------------------------
crypto: improve performance of ciphers in XTS mode
Currently QEMU uses its own XTS cipher mode, however, this has
relatively poor performance.
Gcrypt now includes its own XTS cipher which is at least x2 faster than
what we get with QEMU's on Fedora/RHEL hosts. With gcrypt git master, a
further x5-6 speed up is seen.
This is essential for QEMU's LUKS performance to be viable.
----------------------------------------------------------------
