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.

RTE_EVENT_DEV_CAP_NONSEQ_MODE

Event device is capable of operating in none sequential mode. The path
of the event is not necessary to be sequential. Application can change
the path of event at runtime. If the flag is not set, then event each event
will follow a path from queue 0 to queue 1 to queue 2 etc. If the flag is
set, events may be sent to queues in any order. If the flag is not set, the
eventdev will return an error when the application enqueues an event for a
qid which is not the next in the sequence.

RTE_EVENT_DEV_CAP_RUNTIME_PORT_LINK

Event device is capable of configuring the queue/port link at runtime.
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.

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.

eventdev: set error code in port link/unlink functions

The return value for rte_event_port_{link, unlink}() is defined as the
"number of {links, unlinks} actually established." However, the eventdev
layer's error checking returns negative error values. This commit aligns
the eventdev code with the API definition by having it set rte_errno and
return 0 if it detects an error.

mbuf: fix performance of freeing with non atomic refcnt

When RTE_MBUF_REFCNT_ATOMIC=n, the decrement of the mbuf reference

the performance (seen with TRex traffic generator).

We cannot replace rte_atomic16_add_return() by rte_mbuf_refcnt_update()

lib: fix missing includes in exported headers

    $(sed -n '/^#define \([^ ]\+\).*$/{s//\1/;H;};${x;s/\n//;s/\n/\\|/g;p;}' \
      build/include/rte_config.h) \
    -- build/include/)

We cannot assume external applications will include rte_config.h on their
own, neither directly nor through a -include parameter like DPDK does
internally.

This not only causes obvious compilation failures that can be reproduced
with check-includes.sh such as:

 [...]/rte_memory.h:88:43: error: ‘RTE_CACHE_LINE_SIZE’ was not declared in
