In DSW, in case a port can't produce any events for the application to
consume, the port is considered idle.
To slightly reduce wall-time latency, flush the port's output buffer
in case of such an empty dequeue.

Each workslot is always bound to a specific lcore there is no multi-core
contention to cause cache trashing as a result it is safe to remove the
WFE. Also, in dual workslot dequeue work will mostlikely be available on
the pair workslot making WFE impractical.

Three warnings are commonly disabled in DPDK with make and meson:
* address-of-packed-member
always disabled
* missing-field-initializers
disabled with meson
disabled with make + clang or make + gcc < 4.7
disabled with make + gcc <= 5 for test files and event drivers
* packed-not-aligned
disabled with meson
This change is removing exceptions for missing-field-initializers.
As it is always disabled, some redundant configs are cleaned up.
Now the situation is:
* address-of-packed-member
always disabled
* missing-field-initializers
always disabled
* packed-not-aligned
disabled with meson
It could alternatively be decided to disable missing-field-initializers
only for old gcc (< 6).
The warning packed-not-aligned is not modified in this change.

If an application issues rte_event_enqueue_new_burst() or
rte_event_enqueue_forward_burst() call with a burst of events longer
than the configured max enqueue burst size, DSW allocates credits not
only for events actually enqueued, but for the complete burst. If this
process is repeated, enough credits will have leaked to cause the
event device to backpressure (i.e. disallow) any new enqueue
operations.
In addition, the port-level enqueue xstats will log the wrong number
of events enqueued for oversized enqueues.
This patch makes DSW gracefully handle oversized enqueue bursts.

When net/octeontx is connected to event/octeontx as an event Rx adapter,
PKI aka 'net/octeontx' can forward packets directly to SSO aka
'event/octeontx'.
When pumping traffic to PKI if flow control is disabled internal FIFOs
might be overrun causing partial l2 packets to be enqueued.
SSO receives <31:0> TAG tag calculated by PKI, in normal cases <31:28>
is always 0 which signifies RTE_EVENT_TYPE_ETHDEV. But in case of
partial received packets PKI sets the <31:0> TAG as 0xFFFFFFFF which
is an invalid event type.
Add a check to see if TAG is 0xFFFFFFFF and free the partial receive
packet.

While meson always adds -Wall flag to C compiles, the make build adds extra
warning flags that are not present in the meson build. This addresses that
shortcoming by adding additional warning flags to our builds. The one
omission is the -Wcast-align flag, which though present in make gcc builds,
gives a lot of warnings/errors when used with clang.
The removed warning "-Wunused-parameter" is covered by the "-Wextra"
