[dpdk-dev] [RFC] queue: introduce queue APIs and driver framework

[Honnappa Nagarahalli]

DPDK offers pipeline model of packet processing. One of the key
components of this model is the core to core packet exchange.
rte_ring and rte_event_ring functions are 2 methods provided
currently for core to core communication. However, these two
do not separate the APIs from implementation. This does not
allow using hardware queue implementations in pipeline model.
This change adds queue APIs and driver framework so that
HW queues can be used for core to core communication in
pipeline model.
When different implementations (ex: HW queues and rte_ring) are used
for the same object in different platforms, it is important to
make sure that the application is portable. Hence features of
different implementations must be elevated to the API level, so that
the application writers can make the right choice.
Currently, basic APIs are created, will add more required APIs
as this progresses.
