All the actions associated with application pipelines
tables and ports are now implemented using the new action
APIs. Therefore, thousands of lines of code are eliminated
from the application. The reduced code size is easier to
maintain and extend.

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.

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
handlers (invoked by the pipeline table lookup operation).
* 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.

This API is similar to the blocking API that is already present,
but reply will be received in a separate callback by the caller
(callback specified at the time of request, rather than registering
for it in advance).
Under the hood, we create a separate thread to deal with replies to
asynchronous requests, that will just wait to be notified by the
main thread, or woken up on a timer.

Originally, there was only one type of request which was used
for multiprocess synchronization (hence the name - sync request).
However, now that we are going to have two types of requests,
synchronous and asynchronous, having it named "sync request" is
very confusing, so we will rename it to "pending request". This
is internal-only, so no externally visible API changes.

This overrun cannot currently happen in practice because

Since we have support for the strlcpy function in DPDK, replace all

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.
