This patchset adds crypto backend suppport to vhost_user library,
including a proof-of-concept sample application. The implementation
follows the virtio-crypto specification and have been tested
with qemu 2.9.50 (with several patches applied, detailed later)
with Fedora 24 running in the frontend.

The vhost_user library acts as a "bridge" method that translate
the virtio-crypto crypto requests to DPDK crypto operations, so it
is purely software implementation. However it does require the user
to provide the DPDK Cryptodev ID so it knows how to handle the
virtio-crypto session creation and deletion mesages.

Currently the implementation supports AES-CBC-128 and HMAC-SHA1
cipher only/chaining modes and does not support sessionless mode
yet. The guest can use standard virtio-crypto driver to set up
session and sends encryption/decryption requests to backend. The
vhost-crypto sample application provided in this patchset will
do the actual crypto work.

To make this patchset working, a few tweaks need to be done:

In the host:
1. Download the qemu source code, and apply the patches in:
list.nongnu.org/archive/html/qemu-devel/2017-07/msg04664.html.
As the patches have been out for over 2 months, they cannot be
cleanly applied to the latest code. I have reverted the commits
back to 4c4414a to make the patches applied cleanly.

2. Recompile your qemu.

3. Apply this patchset to latest DPDK code and recompile DPDK.

4. Compile and run vhost-crypto sample application.

./examples/vhost_crypto/build/vhost-crypto -l 11,12,13 -w 0000:86:01.0 \
 --socket-mem 2048,2048

Where 0000:86:01.0 is the QAT PCI address. You may use AES-NI-MB if it is
not available. The sample application requires 3 lcores: 1 master, 1 worker,
and 1 statistics displaying worker. The application will create a UNIX socket
file /tmp/vhost_crypto1.socket.

5. Start your qemu application. Here is my command:

qemu/x86_64-softmmu/qemu-system-x86_64 -machine accel=kvm -cpu host \
-smp 2 -m 1G -hda ~/path-to-your/image.qcow \
-object memory-backend-file,id=mem,size=1G,mem-path=/dev/hugepages,share=on \
-mem-prealloc -numa node,memdev=mem -chardev \
socket,id=charcrypto0,path=/tmp/vhost_crypto1.socket \
-object cryptodev-vhost-user,id=cryptodev0,chardev=charcrypto0 \
-device virtio-crypto-pci,id=crypto0,cryptodev=cryptodev0 

6. Once guest is booted. The Linux virtio_crypto kernel module is loaded by
default. You shall see the following logs in your demsg:

[   17.611723] virtio_crypto virtio0: max_queues: 1, max_cipher_key_len: ...
[   17.612156] virtio_crypto virtio0: will run requests pump with realtime ...
[   18.376100] virtio_crypto virtio0: Accelerator is ready

The virtio_crypto driver in the guest is now up and running.

7. The rest steps can be as same as the Testing section in
https://wiki.qemu.org/Features/VirtioCrypto
