devargs: unify scratch buffer storage

In current design, legacy parser rte_devargs_parse() saved scratch
buffer to devargs.args while new parser rte_devargs_layers_parse() saved
to devargs.data. Code using devargs had to know the difference and
cleaned up memory accordingly - error prone.

This patch unifies scratch buffer to data field, introduces
rte_devargs_reset() function to wrap the memory clean up logic.

net/failsafe: fix parameters parsing

The corrupted code used wrongly snprintf return value as the
number of characters actually copied, in spite of the meaning
is the number of characters which would be generated for the
given input.

It caused to remain zerod bytes between the failsafe command line
non sub device parameters indicates end of string.

Hence, when rte_kvargs_parse tried to parse all parameters, it
got end of string after the first one and the others weren't parsed.

So, if the mac parameters was the first in command line it was
taken while hotplug_poll was left default, and vice versa.

The fix updates the buffer index by dedicated variable contains
the copy size, by the way validates the comma separation.

net/failsafe: fix blank line parsing

When the output of an exec() slave definition is only a single newline
character, the fail-safe currently fails to parse the device with the
value returned by the rte_devargs library.

This behavior is incorrect, because the fail-safe should make a
difference between the absence of a device, and an erroneous device
declaration.

Fix the output sanitization in the case where no newline was at its end
and detect the special case of an absent device. The correct error code
is then returned.

net/failsafe: add fail-safe PMD

Introduce the fail-safe poll mode driver initialization and enable its
build infrastructure.

This PMD allows for applications to benefit from true hot-plugging
support without having to implement it.

It intercepts and manages Ethernet device removal events issued by
slave PMDs and re-initializes them transparently when brought back.
It also allows defining a contingency to the removal of a device, by
designating a fail-over device that will take on transmitting operations
if the preferred device is removed.

Applications only see a fail-safe instance, without caring for
underlying activity ensuring their continued operations.
