memzone: enable IOVA-contiguous reserving

This adds a new flag to request reserved memzone to be IOVA
contiguous. This is useful for allocating hardware resources like

mem: do not use physical addresses in IOVA as VA mode

We already use VA addresses for IOVA purposes everywhere if we're in
RTE_IOVA_VA mode:
 1) rte_malloc_virt2phy()/rte_malloc_virt2iova() always return VA addresses
 2) Because of 1), memzone's IOVA is set to VA address on reserve
 3) Because of 2), mempool's IOVA addresses are set to VA addresses

The only place where actual physical addresses are stored is in memsegs at
init time, but we're not using them anywhere, and there is no external API
to get those addresses (aside from manually iterating through memsegs), nor
should anyone care about them in RTE_IOVA_VA mode.

So, fix EAL initialization to allocate VA-contiguous segments at the start
without regard for physical addresses (as if they weren't available), and
use VA to set final IOVA addresses for all pages.

pipeline: add port in action APIs

This API provides a common set of actions for pipeline input ports to speed
up application development.

Each pipeline input port can be assigned an action handler to be executed
on every input packet during the pipeline execution.

The pipeline library allows the user to define his own input port actions
by providing customized input port action handler. While the user can
still follow this process, this API is intended to provide a quicker
development alternative for a set of predefined actions.

The typical steps to use this API are:
* Define an input port action profile.
* Instantiate the input port action profile to create input port action
  objects.
* Use the input port action to generate the input port action handler
  invoked by the pipeline.
* Use the input port action object to generate the internal data structures
  used by the input port action handler based on given action parameters.

pipeline: add table action APIs

This API provides a common set of actions for pipeline tables to speed up
application development.

Each match-action rule added to a pipeline table has associated data
that stores the action context. This data is input to the table
action handler called for every input packet that hits the rule as
part of the table lookup during the pipeline execution.

The pipeline library allows the user to define his own table
actions by providing customized table action handlers (table
lookup) and complete freedom of setting the rules and their data
(table rule add/delete). While the user can still follow this
process, this API is intended to provide a quicker development
alternative for a set of predefined actions.

The typical steps to use this API are:
* Define a table action profile.
* Instantiate the table action profile to create table action objects.
* Use the table action object to generate the pipeline table action

* Use the table action object to generate the rule data (for the
  pipeline table rule add operation) based on given action parameters.
* Use the table action object to read action data (e.g. stats counters)
  for any given rule.

However, now that we are going to have two types of requests,

convert snprintf to strlcpy

eal: support strlcpy function

The strncpy function is error prone for doing "safe" string copies, so
we generally try to use "snprintf" instead in the code. The function
"strlcpy" is a better alternative, since it better conveys the
intention of the programmer, and doesn't suffer from the non-null
terminating behaviour of it's n'ed brethern.

The downside of this function is that it is not available by default
on linux, though standard in the BSD's. It is available on most
distros by installing "libbsd" package.

This patch therefore provides the following in rte_string_fns.h to ensure
that strlcpy is available there:
* for BSD, include string.h as normal
* if RTE_USE_LIBBSD is set, include <bsd/string.h>
* if not set, fallback to snprintf for strlcpy

Using make build system, the RTE_USE_LIBBSD is a hard-coded value to "n",
but when using meson, it's automatically set based on what is available
on the platform.
