The adapter implementation uses eventdev PMDs to configure the packet
transfer if HW support is available and if not, it uses an EAL service
function that reads packets from ethernet Rx queues and injects these
as events into the event device.

The caps API allows application to retrieve capability information
needed to configure the ethernet Rx adapter for the eventdev and
ethdev pair.
For e.g., the ethdev, eventdev pairing maybe such that all of the
ethdev Rx queues can only be connected to a single event queue, in
this case the application is required to pass in -1 as the queue id
when adding a receive queue to the adapter.

This commit adds a generic queue attribute function. It also removes
the previous rte_event_queue_priority() and priority() functions, and
updates the map files and unit tests to use the new attr functions.

This commit adds a device attribute function, allowing flexible
fetching of device attributes, like port count or queue count.
The unit tests and .map file are updated to the new function.

This commit reworks the port functions to retrieve information
about the port, like the enq or deq depths. Note that "port count"
is a device attribute, and is added in a later patch for dev attributes.

Add in a new rte_event_ring structure type and functions to allow events to
be passed core to core. This is needed because the standard rte_ring type
only works on pointers, while for events, we want to copy the entire, 16B
events themselves - not just pointers to them. The code makes extensive use
of the functions already defined in rte_ring.h

Add in APIs for extended stats so that eventdev implementations can report
out information on their internal state. The APIs are based on, but not
identical to, the equivalent ethdev functions.
