This patch adds missing backslash in host's testpmd command

Without it the command works, but a single core is used
instead of four, which might create confusion.

There is little reason for NUMA support in testpmd to be off by default, so
enable it, and add in a new commandline parameter to disable it, if that is

Extend the LSC event handling to support the device removal as well. The
Verbs library will send several related events, that can conflict
with the LSC event itself.
The event handling has thus been made capable of receiving and signaling
several event types at once.

This new API allows reacting to a device removal.
A device removal is the sudden disappearance of a device from its
bus.
PMDs implementing support for this notification guarantee that the removal
of the underlying device does not incur a risk to the application.
In particular, Rx/Tx bursts and all other functions can still be called
(albeit likely returning errors) without triggering a crash, irrespective
of an application handling this event.

Extended xstats API in ethdev library to allow grouping of stats
logically so they can be retrieved per logical grouping managed
by the application.
Changed existing functions rte_eth_xstats_get_names and
rte_eth_xstats_get to use a new list of arguments: array of ids
and array of values. ABI versioning mechanism was used to
support backward compatibility.
Introduced two new functions rte_eth_xstats_get_all and
rte_eth_xstats_get_names_all which keeps functionality of the
previous ones (respectively rte_eth_xstats_get and
rte_eth_xstats_get_names) but use new API inside.
test-pmd: add support for new xstats API retrieving by id in
testpmd application: xstats_get() and
xstats_get_names() call with modified parameters.
doc: add description for modified xstats API
Documentation change for modified extended statistics API functions.
The old API only allows retrieval of *all* of the NIC statistics
at once. Given this requires a MMIO read PCI transaction per statistic
it is an inefficient way of retrieving just a few key statistics.
Often a monitoring agent only has an interest in a few key statistics,
and the old API forces wasting CPU time and PCIe bandwidth in retrieving
*all* statistics; even those that the application didn't explicitly
show an interest in.
The new, more flexible API allow retrieval of statistics per ID.
If a PMD wishes, it can be implemented to read just the required
NIC registers. As a result, the monitoring application no longer wastes
PCIe bandwidth and CPU time.

Previously, l2fwd-crypto application did not give user the
flexibility to decide which crypto device(s) will be used.
In this patch, a new cryptodev_mask option is added to the
application. Same as portmask, the cryptodev_mask avails the
user to mask out the unwanted crypto devices in the system.

On IBM POWER platform, when mapping /dev/zero file to hugepage memory
space, mmap will not respect the requested address hint. This will cause
the memory initialization for the second process fails. This patch adds
the required mmap flags to make it work. Beside this, users need to set
the nr_overcommit_hugepages to expand the VA range. When
doing the initialization, users need to set both nr_hugepages and
nr_overcommit_hugepages to the same value, like 64, 128, etc.
