examples: move alignment attribute on types for MSVC

Move location of __rte_aligned(a) to new conventional location. The new
placement between {struct,union} and the tag allows the desired
alignment to be imparted on the type regardless of the toolchain being
used for both C and C++. Additionally, it avoids confusion by Doxygen
when generating documentation.

examples/qos_sched: fix buffer overflow on mbuf free

When running the qos_sched app with separated worker and Tx threads, the
app would seg-fault after a short time of handling packets. The root
cause of this turns out to be an incorrect array index when freeing
unsent packets post-Tx. Rather than freeing packets using the "nb_tx"
value i.e. where transmission failed, the function was freeing packets
using the "nb_pkts" value, i.e. going beyond the number of packets
previously received into the buffer.

examples/qos_sched: remove Tx buffering

Since the qos_sched app does batch dequeues from the QoS block, there is
little point in trying to batch further in the app - just send out the
full burst of packets that were received from the QoS block. With modern
CPUs and write-combining doorbells, the cost of doing smaller TX's is
reduced anyway for the worst case.

This patch implements the changes proposed in the deprecation

mbuf: implement generic format for sched field

This patch implements the changes proposed in the deprecation
notes [1][2].

librte_mbuf changes:
The mbuf->hash.sched field is updated to support generic
definition in line with the ethdev traffic manager and meter APIs.
The new generic format contains: queue ID, traffic class, color.

Added public APIs to set and get these new fields to and from mbuf.

librte_sched changes:
In addtion, following API functions of the sched library have
been modified with an additional parameter of type struct
rte_sched_port to accommodate the changes made to mbuf sched field.
(i)rte_sched_port_pkt_write()
(ii) rte_sched_port_pkt_read_tree_path()

librte_pipeline, qos_sched UT, qos_sched app are updated
to make use of new changes.

Also mbuf->hash.txadapter has been added for eventdev txq,
rte_event_eth_tx_adapter_txq_set and rte_event_eth_tx_adapter_txq_get()
are updated to use mbuf->hash.txadapter.txq.

doc:
Release notes updated.
Removed deprecation notice for mbuf->hash.sched and sched API.

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.

The bulk fns for rings returns 0 for all elements enqueued and negative

This change also allows the return value from enq/deq to be used directly

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.
