33cf6be04d ethdev: add sanity checks to functions
The functions rte_eth_rx_queue_count and rte_eth_descriptor_done are
supported by very few PMDs. Therefore, it is best to check for support
for the functions in the ethdev library, so as to avoid run-time crashes
at run-time if the application goes to use those APIs. Similarly, the
port parameter should also be checked for validity.

71594065e2 ethdev: remove duplicated debug functions
The functions for rx/tx burst, for rx_queue_count and descriptor_done in
the ethdev library all had two copies of the code. One copy in
rte_ethdev.h was inlined for performance, while a second was in
rte_ethdev.c for debugging purposes only. We can eliminate the second
copy of the functions by moving the additional debug checks into the
copies of the functions in the header file. [Any compilation for
debugging at optimization level 0 will not inline the function so the
result should be same as when the function was in the .c file.]

d5790b03b3 ethdev: fix link status race condition
Calling the Ethernet driver's link_update function from
rte_eth_dev_start can result in a race condition if the NIC raises
the link interrupt at the same time.
Depending on the interrupt handler implementation, the race can cause
the it to think that it received two consecutive link up interrupts,
and it exits without calling the user callback. Appears to impact
E1000/IGB and virtio drivers only.

6b6861c171 ethdev: check queue state before starting or stopping
Following the same approach taken with dev_started field
in rte_eth_dev_data structure, this patch adds two new fields
in it, rx_queue_state and tx_queue_state arrays, which track
which queues have been started and which not.

This is important to avoid trying to start/stop twice a queue,
which will result in undefined behaviour
(which may cause RX/TX disruption).

Mind that only the PMDs which have queue_start/stop functions
have been changed to update this field, as the functions will
check the queue state before switching it.
