...
Some libraries were missing their dependency on eal, mbuf, mempool,
ring and kvargs.
It is revealed by the linker option "-z defs".

net/virtio-user: add new virtual PCI driver
...
This patch implements another new instance of struct virtio_pci_ops to
drive the virtio-user virtual device. Instead of rd/wr ioport or PCI
configuration space, this virtual pci driver will rd/wr the virtual
device struct virtio_user_hw, and when necessary, invokes APIs provided
by device emulation later to start/stop the device.

net/virtio-user: add device emulation layer
...
Few device emulation layer functions are added for virtio driver to
call:
- virtio_user_start_device()
- virtio_user_stop_device()
- virtio_user_dev_init()
- virtio_user_dev_uninit()
These functions will get called by virtio driver, and they call vhost
adapter layer functions to implement the functionality.
All stats related to virtual user device as logged in virtio_user_dev
structure.

net/virtio-user: add vhost-user adapter layer
...
This patch provides vhost adapter layer implementation. Two main
help functions are provided to upper layer (device emulation):
- vhost_user_setup(), to set up vhost user backend;
- vhost_user_sock(), to talk with vhost user backend.

virtio: restrict vector Rx/Tx to x86 SSSE3
...
Temporary implementation to let virtio operate in non-vec mode for archs
which doesn't support _ssse_ cpuflag.
todo:
1) Move virtio_recv_pkts_vec() implementation to
drivers/virtio/virtio_vec_<arch>.h file.
2) Remove use_simple_rxtx flag, so that virtio/virtio_vec_<arch>.h
files to provide vectored/non-vectored rx/tx apis.
Fixes: fc3d66212fed ("virtio: add vector Rx")
Fixes: c121c8d6d31a ("virtio: add simple Tx")
Fixes: 8d8393fb1861 ("virtio: pick simple Rx/Tx")

virtio: fill Rx avail ring with blank mbufs
...
Add software RX ring in virtqueue.
Add fake_mbuf in virtqueue for wraparound processing.
Fill avail ring with blank mbufs in virtio_dev_vring_start
Add virtio_rxtx.h header file for RTE_VIRTIO_PMD_MAX_BURST.
Would move all rx/tx related declarations into this header file in future.

mem: move librte_malloc to eal/common
...
Move malloc inside eal and create a new section in MAINTAINERS file for
Memory Allocation in EAL.
Create a dummy malloc library to avoid breaking applications that have
librte_malloc in their DT_NEEDED entries.
This is the first step towards using malloc to allocate memory directly
from memsegs. Thus, memzones would allocate memory through malloc,
allowing to free memzones.
