ethdev: fix crash with multiprocess
The data structure for the rx and tx callbacks is local to each process
since it contains function pointers and cannot be shared between
different unique binaries. However, because it is not in
rte_eth_dev_data structure, the array is not getting initialized for
secondary processes - neither is it getting appropriately resized if the
number of RX/TX queues changes. This causes crashes in secondary
processes as they dereference a null pointer in struct rte_eth_dev.
This patch fixes this by introducing an upper-bound on the number of
queues per port that can be configured, and then uses this to make the
array statically sized, thereby avoiding the crashes.

scripts: add ABI checking utility
There was a request for an abi validation utilty for the ongoing ABI stability
work. As it turns out there is a abi compliance checker in development that
seems to be under active development and provides fairly detailed ABI compliance
reports. Its not yet intellegent enough to understand symbol versioning, but it
does provide the ability to identify symbols which have changed between
releases, along with details of the change, and offers developers the
opportunity to identify which symbols then need versioning and validation for a
given update via manual testing.
This script automates the use of the compliance checker between two arbitrarily
specified tags within the dpdk tree. To execute enter the $RTE_SDK directory
and run:
./scripts/validate_abi.sh $GIT_TAG1 $GIT_TAG2 $CONFIG
where $GIT_TAG1 and 2 are git tags and $CONFIG is a config specification
suitable for passing as the T= variable in the make config command.
Note the upstream source for the abi compliance checker is here:
http://ispras.linuxbase.org/index.php/ABI_compliance_checker
It generates a report for each DSO built from the requested tags that developers
can review to find ABI compliance issues.

- Added ixgbe_hw.rx_bulk_alloc_allowed - see ixgbe_hw.rx_vec_allowed description below.
- Added ixgbe_hw.rx_vec_allowed: like with Bulk Allocation, Vector Rx is
enabled or disabled on a per-port level. All queues have to meet the appropriate
preconditions and if any of them doesn't - the feature has to be disabled.
Therefore ixgbe_hw.rx_vec_allowed will be updated during each queues configuration
(rte_eth_rx_queue_setup()) and then used in rte_eth_dev_start() to configure the
appropriate callbacks. The same happens with ixgbe_hw.rx_vec_allowed in a Bulk Allocation

- Bugs fixed:
- Vector scattered packets callback was called regardless the appropriate

- Vector Rx specific preconditions.
- Bulk Allocation preconditions.
