eventdev: negate maintenance capability flag

Replace RTE_EVENT_DEV_CAP_REQUIRES_MAINT, which signaled the need
for the application to call rte_event_maintain(), with
RTE_EVENT_DEV_CAP_MAINTENANCE_FREE, which does the opposite (i.e.,
signifies that the event device does not require maintenance).

This approach is more in line with how other eventdev hardware and/or
software limitations are handled in the Eventdev API.

eventdev: express DLB/DLB2 PMD constraints

This commit implements the eventdev ABI changes required by
the DLB/DLB2 PMDs. Several data structures and constants are modified
or added in this patch, thereby requiring modifications to the
dependent apps and examples.

The DLB/DLB2 hardware does not conform exactly to the eventdev interface.
1) It has a limit on the number of queues that may be linked to a port.
2) Some ports a further restricted to a maximum of 1 linked queue.
3) DLB does not have the ability to carry the flow_id as part
of the event (QE) payload. Note that the DLB2 hardware is capable of
carrying the flow_id.

Following is a detailed description of the changes that have been made.

1) Add new fields to the rte_event_dev_info struct. These fields allow
the device to advertise its capabilities so that applications can take
the appropriate actions based on those capabilities.

struct rte_event_dev_info {
uint32_t max_event_port_links;
/**< Maximum number of queues that can be linked to a single event
* port by this device.
*/

uint8_t max_single_link_event_port_queue_pairs;
/**< Maximum number of event ports and queues that are optimized for
* (and only capable of) single-link configurations supported by this
* device. These ports and queues are not accounted for in
* max_event_ports or max_event_queues.
*/
}

2) Add a new field to the rte_event_dev_config struct. This field allows
the application to specify how many of its ports are limited to a single
link, or will be used in single link mode.

/** Event device configuration structure */
struct rte_event_dev_config {
uint8_t nb_single_link_event_port_queues;
/**< Number of event ports and queues that will be singly-linked to
* each other. These are a subset of the overall event ports and
* queues; this value cannot exceed *nb_event_ports* or
* *nb_event_queues*. If the device has ports and queues that are
* optimized for single-link usage, this field is a hint for how many
* to allocate; otherwise, regular event ports and queues can be used.
*/
}

3) Replace the dedicated implicit_release_disabled field with a bit field
of explicit port capabilities. The implicit_release_disable functionality
is assigned to one bit, and a port-is-single-link-only attribute is
assigned to other, with the remaining bits available for future assignment.

* Event port configuration bitmap flags */
#define RTE_EVENT_PORT_CFG_DISABLE_IMPL_REL (1ULL << 0)
/**< Configure the port not to release outstanding events in
* rte_event_dev_dequeue_burst(). If set, all events received through
* the port must be explicitly released with RTE_EVENT_OP_RELEASE or
* RTE_EVENT_OP_FORWARD. Must be unset if the device is not
* RTE_EVENT_DEV_CAP_IMPLICIT_RELEASE_DISABLE capable.
*/
#define RTE_EVENT_PORT_CFG_SINGLE_LINK (1ULL << 1)

/**< This event port links only to a single event queue.
*
* @see rte_event_port_setup(), rte_event_port_link()
*/

#define RTE_EVENT_PORT_ATTR_IMPLICIT_RELEASE_DISABLE 3
/**
* The implicit release disable attribute of the port
*/

struct rte_event_port_conf {
uint32_t event_port_cfg;
/**< Port cfg flags(EVENT_PORT_CFG_) */
}

This patch also removes the depreciation notice and announce
the new eventdev ABI changes in release note.

eventdev: add device stop flush callback

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().

eventdev: add implicit release disable capability

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.

eventdev: remove default queue overriding

PMDs that only do a specific type of scheduling cannot provide
CFG_ALL_TYPES, so the Eventdev infrastructure should not demand
that every PMD supports CFG_ALL_TYPES.

By not overriding the default configuration of the queue as
suggested by the PMD, the eventdev_common unit tests can pass
on all PMDs, regardless of their capabilities.

RTE_EVENT_QUEUE_CFG_DEFAULT is no longer used by the eventdev layer
it can be removed now. Applications should use CFG_ALL_TYPES
if they require enqueue of all types a queue, or specify which
type of queue they require.

The CFG_DEFAULT value is changed to CFG_ALL_TYPES in event/skeleton,
to not break the compile.

A capability flag is added that indicates if the underlying PMD
supports creating queues of ALL_TYPES.
