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 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.

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.

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.
