57e20572ac eventdev: fix possible use of uninitialized var
Fix the logic for the case of event queue allowing all schedule types.

Compiler warning pointing to this error (with LTO enabled):
error: ‘sched_type’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]

cc7b73ea9e eventdev: add new software timer adapter
This patch introduces a new version of the event timer adapter software
PMD. In the original design, timer event producer lcores in the primary
and secondary processes enqueued event timers into a ring, and a
service core in the primary process dequeued them and processed them
further.  To improve performance, this version does away with the ring
and lets lcores insert timers directly into timer skiplist data
structures; the service core directly accesses the lists as well, when
looking for timers that have expired.

To compare the burst and non-burst performance of the original and new
versions of the software event timer adapter, I ran the following
commands:

$ sudo ./build/app/dpdk-test-eventdev -c 0xFFE -s 0xC --vdev=event_sw0 \
-- --test=perf_queue --plcores=4,5,6 --wlcore=7,8,9 --stlist=p \
--prod_type_timerdev --worker_deq_depth=32

$ sudo ./build/app/dpdk-test-eventdev -c 0xFFE -s 0xC --vdev=event_sw0 \
-- --test=perf_queue --plcores=4,5,6 --wlcore=7,8,9 --stlist=p \
--prod_type_timerdev_burst --worker_deq_depth=32

With the new version, I see a 151% improvement in throughput for the
non-burst case, and a 270% improvement in throughput for the burst case.
I also see a 53% improvement in arm latency in the non-burst case and a
65% improvement in arm latency in the burst case.

Note: To perform the test,  I commented out a check in the original
version that checks the adapter tick interval against a minimum value.

80bdf91dc8 eventdev: promote adapter functions as stable
Promote the adapter functions and rte_event_port_unlinks_in_progress()
as stable as it's been added for a while now and multiple drivers and
test application like test-eventdev has been tested using the adapter APIs.

f8e9989606 remove useless constructor headers
A constructor is usually declared with RTE_INIT* macros.
As it is a static function, no need to declare before its definition.
The macro is used directly in the function definition.

519d8efa1c eventdev: fix resetting software timer
Fix the call to rte_timer_reset_sync() in sw_event_timer_cb().  The
second parameter is the number of ticks, the third is the timer type.

34345a9b69 eventdev: fix build with icc
ICC complains about variable being used before its value is set.
Since the variable is only assigned in the for loop,
its declaration is moved inside and is initialized.

lib/librte_eventdev/rte_event_timer_adapter.c(708): error #592:
variable "ret" is used before its value is set
        RTE_SET_USED(ret);

If an eventdev PMD does not wish to provide event timer adapter ops
definitions, the library will fall back to a default software
implementation whose entry points are added by this commit.
