Multiple PMDs have dummy/noop Rx/Tx packet burst functions.
These dummy functions are very simple, introduce a common function in
the ethdev and update drivers to use it instead of each driver having
its own functions.

Currently, most ethdev callback API use queue ID as parameter, but Rx
and Tx queue release callback use queue object which is used by Rx and
Tx burst data plane callback.
To align with other eth device queue configuration callbacks:
- queue release callbacks are changed to use queue ID
- all drivers are adapted

Add Rx descriptor limit for number of segments per MTU.
PMD doesn't support Jumbo Rx scatter gather hence set 1 segment per
MTU. Some applications can adjust mbuf_size based on this value.
For others PMD detects the condition where Rx packet length cannot
be held by configured mbuf size and logs the message.

PMD handles fast path completions in the Rx handler and control path
completions in the interrupt handler. They both are processing
completions from the same fastpath completion queue. There is a
potential for race condition when these two paths are processing
the completions from the same queue and trying to updating Rx Producer.
Add a fastpath Rx lock between these two paths to close this race.

In some cases, DPDK application may send packets
while PMD is going through load or unload flow.
This causes firmware to access invalid/unallocated
memory to process transmit buffer. Which results in
error on PCI bus and chip further blocks access to host,
causing a DMAE timeout.
Fix this issue by installing dummy empty transmit and receive
handlers at the beginning of unload path (rte_eth_dev_stop())
and install actual transmit and receive handlers after successful
load of the PMD port (rte_eth_dev_start()). This way, application
won't be able to send packets while device is going through
load/unload flow.

The helper rte_eth_dma_zone_reserve() is called by PMDs
when probing a new port.
It creates a new memzone with an unique name.
The name of this memzone was using the name of the driver
doing the probe.
In order to avoid assigning the driver before the end of the probing,
the driver name is removed from these memzone names.
The ethdev name (data->name) is not used because it may be too long
and may be not set at this stage of probing.

PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated for a while.
As explained in [1], these flags were kept to let the applications and
PMDs move to the new flag. There is also a need to support Rx vlan
offload without vlan strip (at least for the ixgbe driver).
This patch renames the old flags for this feature, knowing that some
PMDs were using PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT to indicate that
the vlan tci has been saved in the mbuf structure.
It is likely that some PMDs do not set the proper flags when doing vlan
offload, and it would be worth making a pass on all of them.

If you stop and start the driver, the rx queue will have the previous
index values when programming the adapter. Therefore, we should always
reset the queue indices when the rx ring is setup. Note: We need to
clear (write) the status block's completion queue index since it is
possibly in a read cache.
Tidy some init code to make it clearer what the defaults are.
