Whether it is allowed to call Rx/Tx functions for a stopped queue
was undocumented. Some PMDs make this behavior a no-op
either by explicitly checking the queue state
or by the way how their routines are implemented or HW works.
No-op behavior may be convenient for application developers.
But it also means that pollers of stopped queues
would go all the way down to PMD Rx/Tx routines, wasting cycles.
Some PMDs would do a check for the queue state on data path,
even though it may never be needed for a particular application.
Also, use cases for stopping queues or starting them deferred
do not logically require polling stopped queues.
Use case 1: a secondary that was polling the queue has crashed,
the primary is doing a recovery to free all mbufs.
By definition the queue to be restarted is not polled.
Use case 2: deferred queue start or queue reconfiguration.
The polling thread must be synchronized anyway,
because queue start and stop are non-atomic.
Prohibit calling Rx/Tx functions on stopped queues.

When xstats location is null in rte_eth_xstats_get() the return value

zero while others return the required number of elements.
In this patch, special parameter combinations are restricted:
1. highlight that xstats location may be null if and only if n is 0.
2. amend n parameter description to specify that if n is lower than
the required number of elements, the function returns the required
number of elements.
3. specify that if n is zero, the xstats must be NULL, the function
returns the required number of elements (a duplicate which should
help to not very attentive readers).
Add sanity check for null xstats and non-zero n case on API level to
make it unnecessary to care about it in drivers.

Transport Processor (TP) on the NIC delivers the incoming packets
from the wire to NIC's DMA engine to place the packets in Rx buffers.
TP sends signal towards the Multi-Port Switch (MPS) near the MAC when
the Rxqs run out of Rx buffers posted by driver. These MPS buffer drop
stats are already accounted for in imissed counters. However, if a
large number of Rxqs run out of Rx buffers simultaneously, then the
TP can start dropping packets by itself when there is heavy congestion
on the channel and hence could not inform to the MPS. So, track these
packets dropped by TP in imissed counters. Also add xstats for these
counters.
