The new WRR sequence applicable after queue add/del is set
up after setting the new queue state, so a memory allocation
failure will leave behind an incorrect state.
This change separates the memory sizing + allocation for the
Rx poll and WRR array from calculation of the WRR sequence.
If there is a memory allocation failure, existing Rx queue

The name private_data is confusing in these APIs:
rte_cryptodev_sym_session_set_private_data()
rte_cryptodev_sym_session_get_private_data()
It refers to data added at the end of the session hdr for
use by the application.
The session already contains sess_private_data[index]
which is used to store private pmd data and most references to private
data refer to that.
e.g. external apis
rte_cryptodev_sym_get_private_session_size() and internal
set/get_session_private_data() refer to sess_private_data[].
So rename to user_data, i.e.
rte_cryptodev_sym_session_set_user_data()
rte_cryptodev_sym_session_get_user_data()

Some DPDK applications wrongly assume these requirements:
- no hotplug, i.e. ports are never detached
- all allocated ports are available to the application
Such application iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.
In order to fix this common mistake in all external applications,
the function rte_eth_dev_count is deprecated, while introducing

Such application iterates over ports by its own mean.
The most common pattern is to request the port count and

There are three consequences when using such wrong design:
- new ports having an index higher than the port count won't be seen
- old ports being detached (RTE_ETH_DEV_UNUSED) can be seen as ghosts
- failsafe sub-devices (RTE_ETH_DEV_DEFERRED) will be seen by the application
Such mistake will be less common with growing hotplug awareness.

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().

The default adapter configuration callback is invoked when a Rx
queue is added to the adapter and the adapter detects that a SW
service is needed. The adapter needs to re-configure the device
with an additional port and to do do, it needs to stop the
device and restart it after it is done reconfiguring it. This
patch adds code to check the return code of
rte_event_dev_start() for both when the reconfiguration fails
and when it succeeds and introduces a new error code (-EIO)
for the first case.

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.

This commit introduces a capability for disabling the "implicit" release

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.

Many exported headers rely on definitions found in rte_config.h without
including it, as shown by the following command:
grep -L '^#include <rte_config.h>' -- \
$(grep -Rl \
$(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
this scope
#define __rte_cache_aligned __rte_aligned(RTE_CACHE_LINE_SIZE)
