vhost: support virtio status message

This patch adds support to the new Virtio device get status
Vhost-user message.

The driver can send this new message to read the device status.

One of the uses of this message is to ensure the feature negotiation has
succeeded.  According to the virtio spec, after completing the feature
negotiation, the driver sets the FEATURE_OK status bit and re-reads it
to ensure the device has accepted the features.

This patch also clears the FEATURE_OK status bit if the feature
negotiation has failed to let the driver know about his failure.

pci: keep API compatibility with mmap values

The function pci_map_resource() returns MAP_FAILED in case of error.
When replacing the call to mmap() by rte_mem_map(),
the error code became NULL, breaking the API.
This function is probably not used outside of DPDK,
but it is still a problem for two reasons:
- the deprecation process was not followed
- the Linux function pci_vfio_mmap_bar() is broken for i40e

The error code is reverted to the Unix value MAP_FAILED.
Windows needs to define this special value (-1 as in Unix).
After proper deprecation process, the API could be changed again
if really needed.

Because of the switch from mmap() to rte_mem_map(),
another part of the API was changed: "int additional_flags"
are defined as "additional flags for the mapping range"
without mentioning it was directly used in mmap().
Currently it is directly used in rte_mem_map(),
that's why the values rte_map_flags must be mapped (sic) on the mmap ones
in case of Unix OS.

These are side effects of a badly defined API using Unix values.

net/hns3: fix inserted VLAN tag position in Tx

Based on hns3 network engine, in order to configure hardware VLAN insert
offload in Tx direction, PMD driver reads the VLAN tags from the
vlan_tci_outer and vlan_tci of the structure rte_mbuf, fills them into
the Tx Buffer Descriptor and sets the related offload flag for every
packet.

Currently, there are two VLAN related problems in the 'tx_pkt_burst' ops
implementation function:
1) When setting the related offload flag, PMD driver inserts the VLAN
   tag into the position that close to L3 header. So, when upper
   application sends a packet with a VLAN tag in the data buffer, the
   VLAN offloaded by hardware will be added to the wrong position. It is
   supposed to add the VLAN tag from the rte_mbuf to the position close
   to the MAC header in the packet when using VLAN insertion.

   And when PF PVID is enabled by calling the API function named
   rte_eth_dev_set_vlan_pvid or VF PVID is enabled by hns3 PF kernel
   ether driver, the VLAN tag from the structure rte_mbuf to enable the
   VLAN insertion should be filled into the position that close to L3
   header to avoid to be overwritten by the PVID which will always be
   inserted in the position that close to the MAC address.

2) When sending multiple segment packets, VLAN information is required
   to be filled into the first Tx Buffer descriptor. However, currently
   hns3 PMD driver incorrectly placed it in the last Tx Buffer
   Descriptor. This results in VLAN insert offload failure when sending
   multiple segment packets.

This patch fixed them by filling the VLAN information into the position
of the Tx Buffer Descriptor.

The problem is that missing checking the return value of calling the API
rte_mp_action_register during initialization. If registering an action
function for primary and secondary communication failed, the secondary

app/testpmd: use clock time in throughput calculation

The throughput calculation requires a counter that measures
passing of time. However, the kernel saves and restores the PMU
state when a thread is unscheduled and scheduled. This ensures
that the PMU cycles are not counted towards a thread that is
not scheduled. Hence, when RTE_ARM_EAL_RDTSC_USE_PMU is enabled,
the PMU cycles do not represent the passing of time.
This results in incorrect calculation of throughput numbers.
Use clock_gettime system call to calculate the time passed since
last call.

vhost: introduce async enqueue for split ring

This patch implements async enqueue data path for split ring. 2 new
async data path APIs are defined, by which applications can submit
and poll packets to/from async engines. The async engine is either
a physical DMA device or it could also be a software emulated backend.
The async enqueue data path leverages callback functions registered by
applications to work with the async engine.

vhost: introduce async enqueue registration API

Performing large memory copies usually takes up a major part of CPU
cycles and becomes the hot spot in vhost-user enqueue operation. To
offload the large copies from CPU to the DMA devices, asynchronous
APIs are introduced, with which the CPU just submits copy jobs to
the DMA but without waiting for its copy completion. Thus, there is
no CPU intervention during data transfer. We can save precious CPU
cycles and improve the overall throughput for vhost-user based
applications. This patch introduces registration/un-registration
APIs for vhost async data enqueue operation. Together with the
registration APIs implementations, data structures and the prototype
of the async callback functions required for async enqueue data path
are also defined.
