1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

app/eventdev: add pipeline queue test

This is a pipeline queue test case that aims at testing the following:
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The pipeline queue test configures the eventdev with Q queues and P ports,
where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers.

The user can choose the number of workers and number of stages through the
--wlcores and the --stlist application command line arguments respectively.
The probed ethernet devices act as producer(s) for this application.

The ethdevs are configured as event Rx adapters that enables them to
injects events to eventdev based the first stage schedule type list
requested by the user through --stlist the command line argument.

Based on the number of stages to process(selected through --stlist),
the application forwards the event to next upstream queue and when it
reaches last stage in the pipeline if the event type is ATOMIC it is
enqueued onto ethdev Tx queue else to maintain ordering the event type is
set to ATOMIC and enqueued onto the last stage queue.
On packet Tx, application increments the number events processed and print
periodically in one second to get the number of events processed in one
second.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline queue test:

event/sw: remove stale IQ references when reconfigured

This commit fixes a bug in which, when the sw PMD is reconfigured, it would
leave stale IQ chunk pointers in each queue's IQ structure. Now, the PMD
initializes all IQs at eventdev start time and releases all IQ chunk
pointers at eventdev stop time (which has the consequence that any events
in a queue when the eventdev is stopped will be lost). This approach should
be resilient to any reconfiguration done between the stop and start, such
as adding or removing queues.

This commit also fixes two potential issues in iq_chunk.h. iq_init()
now initializes the IQ's count field to 0, and iq_dequeue_burst() sets
iq->head to the appropriate next pointer.

If the flag is not set, the eventdev queue/port link is only can be
configured during  initialization.

RTE_EVENT_DEV_CAP_MULTIPLE_QUEUE_PORT

Event device is capable of setting up the link between multiple queue
with single port. If the flag is not set, the eventdev can only map a
single queue to each port or map a single queue to many port.

This commit adds a OPDL implementation of the eventdev API. The
implementation here is intended to enable the community to use
the OPDL infrastructure under eventdev API.

The main components of the implementation is three files:
  - opdl_evdev.c              Creation, configuration, etc
  - opdl_evdev_xstats.c       helper function to support stats collection
  - opdl_evdev.h              include the main data structure of opdl
                              device and all the function prototype
                              need to be exposed to support eventdev API.

  - opdl_evdev_init.c         implement all initailization helper function

This commit only adds the implementation, no existing DPDK files
are modified.

OPDL ring is the core infrastructure of OPDL PMD. OPDL ring library
provide the core data structure and core helper function set. The Ring
implements a single ring multi-port/stage pipelined packet distribution
mechanism. This mechanism has the following characteristics:

• No multiple queue cost, therefore, latency is significant reduced.
• Fixed dependencies between queue/ports is more suitable for complex.
  fixed pipelines of stateless packet processing (static pipeline).

eventdev: add implicit release disable capability

This commit introduces a capability for disabling the "implicit" release
functionality for a port, which prevents the eventdev PMD from issuing
outstanding releases for previously dequeued events when dequeuing a new
batch of events.

If a PMD does not support this capability, the application will receive an
error if it attempts to setup a port with implicit releases disabled.
Otherwise, if the port is configured with implicit releases disabled, the
application must release each dequeued event by invoking
rte_event_enqueue_burst() with RTE_EVENT_OP_RELEASE or
RTE_EVENT_OP_FORWARD.

event/sw: use dynamically-sized IQs

This commit introduces dynamically-sized IQs, by switching the underlying
data structure from a fixed-size ring to a linked list of queue 'chunks.'
This has a number of benefits:
- Certain corner cases were observed in which all of a pipeline's flows
  could be pinned to one port for extended periods, effectively turning a
  multi-core pipeline into single-core one. This was caused by an event
  producer having a larger new_event_threshold than the IQ depth, and
  injecting large numbers of packets that are ultimately backpressured in a
  worker's rx_ring, causing those packets' flows to be scheduled to that
  port.
  The dynamically sized IQ does not have this problem because each IQ can
  grow large enough to store all the system's events, such that
  backpressure will not reach the worker_ring.
- Slight performance improvement (~1-2%) in high throughput scenarios,
  tested with eventdev_pipeline_sw_pmd.

This implementation has a small increase in the queue storage memory
footprint (~70KB). This commit also removes the iq_size xstat, which no
longer applies to this implementation.

event/sw: fix queue memory leak and multi-link bug

This commit reinitializes a queue before it is reconfigured, such that
reorder buffer memory is not leaked.

This bug masked a few other problems, which this commit corrects as well:
- sw_port_link() allowed a port to link to a queue twice, such that the
  port could then successfully unlink the queue twice. Now the link
  function checks whether a port is already linked to the queue, and if so
  returns success but doesn't assign the a port a second slot in the
  queue's cq map.
- test_eventdev.c's test_eventdev_unlink() was unlinking a queue twice
  from the same port, and expecting the second unlink to succeed. Now the
  test unlinks, links, then unlinks again.
- test_eventdev.c's test_eventdev_link_get() was linking a single queue but
  expecting the unlink function to return nb_queues (where nb_queues > 1).
  The test now checks for a return value of 1.
