Currently there are limitations in the virthcnl.h interface that only
allow a maximum of 16 queues to be used by a VF driver. Add support in
virtchnl.h to allow a VF driver to request >16 queues. Also, the RSS
qregion size is currently assumed to be the max number of queues a VF
can request and/or is given on initialization. With larger VFs this
assumption can no longer be made, so add a new op to support querying
the max RSS qregion size.
In order to request more queues than the initially given queues the VF
driver needs to use the VIRTCHNL_OP_REQUEST_QUEUES opcode.
The VF is given more >16 queues it should use the new
VIRTCHNL_OP_GET_MAX_RSS_QREGION to determine its max qregion size. This
is needed to correctly configure the RSS LUT and/or configure filters
based on queue base/offset and queue region size.
If the VF is configuring >16 queues it should use the following opcodes
to configure the qeueus and interrupts after successfully requesting
them.
VIRTCHNL_OP_MAP_QUEUE_VECTOR
VIRTCHNL_OP_ENABLE_QUEUES_V2
VIRTCHNL_OP_DISABLE_QUEUES_V2
Also, add support in virtchnl_vc_validate_vf_msg() to validate the above
messages. As a part of this move the virtchnl_vector_limits enumeration
directly above the function it's used.
The patch also update base code release version in readme.

Change the iavf base code as driver common library, it is used by iavf
PMD now, and it can be used by other Intel SR-IOV PMDs in the future.
