ecaed092b6 ring: return remaining entry count when dequeuing
Add an extra parameter to the ring dequeue burst/bulk functions so that
those functions can optionally return the amount of remaining objs in the
ring. This information can be used by applications in a number of ways,
for instance, with single-consumer queues, it provides a max
dequeue size which is guaranteed to work.

14fbffb0aa ring: return free space when enqueuing
Add an extra parameter to the ring enqueue burst/bulk functions so that
those functions can optionally return the amount of free space in the
ring. This information can be used by applications in a number of ways,
for instance, with single-producer queues, it provides a max
enqueue size which is guaranteed to work. It can also be used to
implement watermark functionality in apps, replacing the older
functionality with a more flexible version, which enables apps to
implement multiple watermark thresholds, rather than just one.

cfa7c9e6fc ring: make bulk and burst return values consistent
The bulk fns for rings returns 0 for all elements enqueued and negative
for no space. Change that to make them consistent with the burst functions
in returning the number of elements enqueued/dequeued, i.e. 0 or N.
This change also allows the return value from enq/deq to be used directly
without a branch for error checking.

edabd7fef5 examples/qos_sched: fix dequeue from ring
The app_worker_thread() and app_mixed_thread() use rte_ring_sc_dequeue_bulk
to dequeue packets from the ring and this imposes restriction on number of
packets in software ring to be greater than the specified value to start
actual dequeue operation, thus, adds latency to those packets. Therefore,
rte_ring_sc_dequeue_bulk is replaced with rte_ring_sc_dequeue_burst.

d827c2695e examples/qos_sched: fix flow pause after 2M packets
After enable vector pmd, qos_sched only send 32 packets every burst.
That will cause some packets not transmitted and therefore mempool
will be drain after a while.
App qos_sched now will re-send the packets which failed to send out in
previous tx function.

3031749c2d remove trailing whitespaces
This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].
