When an event device is stopped, it drains all event queues and ports.
These events may contain pointers, so to prevent memory leaks eventdev now
supports a user-provided flush callback that is called during the queue
drain process. This callback is stored in process memory, so the callback
must be registered by any process that may call rte_event_dev_stop().
This commit also clarifies the behavior of rte_event_dev_stop().

Previously, the sw PMD would enqueue either all or no events, depending on
if enough inflight credits were available for the new events in the burst.
If a port is enqueueing a large burst (i.e. a multiple of the credit update
quanta), this can result in suboptimal performance, and requires an
understanding of the sw PMD implementation (in particular, its credit
scheme) to tune an application's burst size.
This affects software that enqueues large bursts of new events, such as the
ethernet event adapter which uses a 128-deep event buffer, when the input
packet rate is sufficiently high.
This change makes the sw PMD enqueue as many events as it has credits, if
there are any new events in the burst.

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.

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.

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.

This commit adds a new statistic to the SW eventdev PMD.
The statistic shows how many packets were sent from a
queue to a port. This provides information on how traffic
from a specific queue is being load-balanced to worker cores.
Note that these numbers should be compared across all queue
stages - the load-balancing does not try to perfectly share
each queue's traffic, rather it balances the overall traffic
from all queues to the ports.
The statistic is printed from the rte_eventdev_dump() function,
as well as being made available via the xstats API.
Unit tests have been updated to expect more per-queue statistics,
and the correctness of counts and counts after reset is verified.

When taking events from a port, we checked the history list to check if the
event needed to be put back in order i.e. originally came from a reordered
queue type. The check for reordering involved checking if the reorder
buffer entry pointer was null. However, after that pointer was used it was
never cleared to null again.
This caused problems when we had mixed reordered and atomic or parallel
events, as the events from the latter two queue types were misidentified as
needing reordering. This let in some cases to crashes, but mostly led to
dropping events, and then application lock-up.

This patch returns a credit when an rte_event is

credit was leaked from the system.
Note that the eventdev instance does not attempt
to free any resources that the rte_event owns. As
a result, resources owned by the rte_event are leaked.
Eg. if the rte_event represents an rte_mbuf, the mbuf
will not be freed, and causes a leak from the mempool.
