eventdev: add weight and affinity to queue attributes

Extended eventdev queue QoS attributes to support weight and affinity.
If queues are of the same priority, events from the queue with highest
weight will be scheduled first. Affinity indicates the number of times,
the subsequent schedule calls from an event port will use the same event
queue. Schedule call selects another queue if current queue goes empty
or schedule count reaches affinity count.

To avoid ABI break, weight and affinity attributes are not yet added to
queue config structure and rely on PMD for managing it. New eventdev op
queue_attr_get can be used to get it from the PMD.

When the application decides to migrate the event port to another lcore
or teardown the current lcore it may to call `rte_event_port_quiesce`
to make sure that all the data associated with the event port are released
from the lcore, this might also include any prefetched events.

While releasing the event port from the lcore, this function calls the
user-provided flush callback once per event.

eventdev: fix clang C++ include

When compiling on FreeBSD with clang and include checking enabled,
errors are emitted due to differences in how empty structs/unions are
handled in C and C++, as C++ structs cannot have zero size.

lib/eventdev/rte_eventdev.h:992:2: error:
union has size 0 in C, non-zero size in C++

Since the contents of the union are all themselves of zero size,
the actual union wrapper is unnecessary. We therefore remove it for C++
builds - though keep it for C builds for safety and clarity of
understanding the code. The alignment constraint on the union is
unnecessary in the case where the whole struct is aligned on a 16-byte
boundary, so we add that constraint to the overall structure to ensure
it applies for C++ code as well as C.

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: add usage hints to port configure API

This commit introduces 3 flags to the port configuration flags.
These flags allow the application to indicate what type of work
is expected to be performed by an eventdev port.

The three new flags are
- RTE_EVENT_PORT_CFG_HINT_PRODUCER (mostly RTE_EVENT_OP_NEW events)
- RTE_EVENT_PORT_CFG_HINT_CONSUMER (mostly RTE_EVENT_OP_RELEASE events)
- RTE_EVENT_PORT_CFG_HINT_WORKER (mostly RTE_EVENT_OP_FORWARD events)

These flags are only hints, and the PMDs must operate under the
assumption that any port can enqueue an event with any type of op.

lib: remove librte_ prefix from directory names

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
