This patch adds new api ``rte_event_eth_rx_adapter_queue_stats_get`` to
retrieve queue stats. The queue stats are in the format
``struct rte_event_eth_rx_adapter_queue_stats``.
For resetting the queue stats,
``rte_event_eth_rx_adapter_queue_stats_reset`` api is added.
The adapter stats_get and stats_reset apis are also updated to
handle queue level event buffer use case.

Added per queue buffer. To configure per queue event buffer size,
application sets rte_event_eth_rx_adapter_params::use_queue_event_buf
flag as true while using rte_event_eth_rx_adapter_create_with_params().
The per queue event buffer size is populated in
rte_event_eth_rx_adapter_queue_conf::event_buf_size and passed
to rte_event_eth_rx_adapter_queue_add().

Currently event buffer is static array with a default size defined
internally.
To configure event buffer size from application,
rte_event_eth_rx_adapter_create_with_params() API is added which
takes struct rte_event_eth_rx_adapter_params to configure event
buffer size in addition other params. The event buffer size is
rounded up for better buffer utilization and performance. In case
of NULL params argument, default event buffer size is used.

Include vector configuration into the structure
``rte_event_eth_rx_adapter_queue_conf`` that is used to configure
Rx adapter ethernet device Rx queue parameters.
This simplifies event vector configuration as it avoids splitting

Add event vector support for event eth Rx adapter, the implementation
creates vector flows based on port and queue identifier of the received
mbufs.
The flow id for SW Rx event vectorization will use 12-bits of queue
identifier and 8-bits port identifier when custom flow id is not set
for simplicity.

Introduce event ethernet Rx adapter event vector capability.
If an event eth Rx adapter has the capability of
RTE_EVENT_ETH_RX_ADAPTER_CAP_EVENT_VECTOR then a given Rx queue
can be configured to enable event vectorization by passing the
flag RTE_EVENT_ETH_RX_ADAPTER_QUEUE_EVENT_VECTOR to
rte_event_eth_rx_adapter_queue_conf::rx_queue_flags while configuring
Rx adapter through rte_event_eth_rx_adapter_queue_add().
The max vector size, vector timeout define the vector size and
mempool used for allocating vector event are configured through
rte_event_eth_rx_adapter_queue_add. The element size of the element
in the vector pool should be equal to
sizeof(struct rte_event_vector) + (vector_sz * sizeof(uintptr_t))
Application can use `rte_event_vector_pool_create` to create the
vector mempool used for
rte_event_eth_rx_adapter_queue_conf::vector_mp.
The Rx adapter would be responsible for vectorizing the mbufs
based on the flow, the vector limits configured by the application
and add the vector event of mbufs to the event queue set via
rte_event_eth_rx_adapter_queue_conf::ev::queue_id.
It should also mark rte_event_vector::union_valid and fill
rte_event_vector::port, rte_event_vector::queue.

This a revert of the commit 569758758d ("eventdev: add Rx timestamp").
If the Rx timestamp is not configured on the ethdev port,
there is no reason to set one.
Also the accuracy of the timestamp was bad because set at a late stage.
Anyway there is no trace of the usage of this timestamp.

Keep the old functions and macros but mark them as deprecated
for this release.
The "--master-lcore" command line option is also deprecated
