d9a42a69fe ethdev: deprecate port count function
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
the new functions rte_eth_dev_count_avail and rte_eth_dev_count_total.

The port dequeue depth value has to be compared against the maximum
allowed dequeue depth reported by the event drivers.

6bf570a991 app/eventdev: add pipeline atq test
This is a pipeline test case that aims at testing the following with
``all types queue`` eventdev scheme.
1. Measure the end-to-end performance of an event dev with a ethernet dev.
2. Maintain packet ordering from Rx to Tx.

The atq queue test functions as same as ``pipeline_queue`` test.
The difference is, It uses, ``all type queue scheme`` instead of separate
queues for each stage and thus reduces the number of queues required to
realize the use case.

Note: The --prod_type_ethdev is mandatory for running the application.

Example command to run pipeline atq test:
sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
--test=pipeline_atq --wlcore=1 --prod_type_ethdev --stlist=ao
