event/sw: fix get of single xstat value
This commit allows the xstats_get() API to return just a single
value based on its ID. Previously, the "ret_n_lt_stats" value
set to 1 ensured a check to take place that the array was larger
than the available xstats.
The xstats_get() API allows retriving of individual stats - hence
this check should be removed - by setting "ret_n_lt_stats" to zero.

mempool/octeontx: move mbox from event to mempool
Octeontx mempool pmd need mailbox for pool setup.
That mailbox was defined at drivers/event/octeontx.
So mempool has dependency on event/octeontx driver and
commit:
8700239f7767 has added make rule which makes sure event/*
get build before mempool, but this rule introduces
cyclic dependency and may create problem to future
feature addition in drivers/Makefile.
Same problem noticed and reported in below thread:
http://dpdk.org/ml/archives/dev/2017-October/079187.html
The patch solves problem by moving mbox definition from
drivers/event/octeontx to drivers/mempool/octeontx.
Moving mbox files involves below changes:
* Renamed ssovf_mbox.[ch] --> octeontx_mbox.[ch]
* Renamed ssovf_probe.c --> octeontx_ssovf.c
* Introduced pool logger file.
* Moved API from rte_pmd_octeontx_ssovf_version.map to
rte_mempool_octeontx_version.map.
* Respective Makefile changes done in
drivers/event/octeontx/Makefile and drivers/mempool/octeontx/Makefile.

This patch introduces new ethdev generic API for Traffic Metering and
Policing (MTR), which is yet another standard RX offload for Ethernet
devices.
Similar to rte_flow and rte_tm APIs, the configuration of MTR objects is
done in their own namespace (rte_mtr) within the librte_ether library.
Main features:
1. Traffic metering: determine the color for the current packet (green,
yellow, red) based on history maintained by the MTR object. Supported
algorithms: srTCM (RFC 2697), trTCM (RFC 2698 and RFC 4115).
2. Policing (per meter output color actions): re-color the packet (keep
or change the meter output color) or drop the packet.
3. Statistics

to host as below:
in VM guest:
Capabilities: [70] MSI-X: Enable+ Count=5 Masked-
in Host:
Capabilities: [70] MSI-X: Enable+ Count=5 Masked-
That was because in pci_reset_function, it first reads the
PCI configure and set FLR reset, and then writes PCI configure
as restoration. But not all the writing are successful to Host.
Because vfio-pci driver doesn't allow directly write PCI MSI-X
Cap.

when kernel version is >= 3.19 because these APIs are implemented in
this Linux kernel version.
But these APIs only exported beginning from Linux kernel 4.5, so before
this Linux kernel version igb_uio kernel module is not usable,
and giving following warnings:
"igb_uio: Unknown symbol pci_msi_unmask_irq"
"igb_uio: Unknown symbol pci_msi_mask_irq"
The support for these APIs increased to Linux kernel >= 4.5
For older version of Linux kernel unmask_msi_irq() and mask_msi_irq()
are used but these functions are not exported at all.
Instead of these functions switched back to previous implementation in
igb_uio for MSI-X, and for MSI used igbuio_msi_mask_irq() from [1].

eal: call plugin init before device parse
Default eal_init code calls

1. eal_option_device_parse
2. rte_bus_scan
IOVA commit:
cf408c224 missed on calling eal_plugins_init before
eal_option_device_parse, rte_bus_scan and that introduced below
regression for shared mode:
