[dpdk-dev] [PATCH v3] eal: fix libabi macro for device generalization patches

[Shreyansh Jain <shreyansh.jain@nxp.com>]

rte_device/driver generalization patches [1] were merged without a change
in the LIBABIVER macro. This patches bumps the macro of affected libs.
(librte_eal was already bumped; libcryptodev and libetherdev have been
bumped).

Details of ABI/API changes:
- EAL (version not bumped)
  |- type field was removed from rte_driver
  |- rte_pci_device now embeds rte_device
  |- rte_pci_resource renamed to rte_mem_resource
  |- numa_node and devargs of rte_pci_driver is moved to rte_driver
  |- APIs for device hotplug (attach/detach) moved into EAL
  |- API rte_eal_pci_device_name added for PCI device naming
  |- vdev registration API introduced (rte_eal_vdrv_register,
  |  rte_eal_vdrv_unregister

- librte_crypto (v 1=>2)
  |- removed rte_cryptodev_create_unique_device_name API
  |- moved device naming to EAL

- librte_ethdev (v 4=>5)
  |- rte_eth_dev_type is removed
  |- removed dev_type from rte_eth_dev_allocate API
  |- removed API rte_eth_dev_get_device_type
  |- removed API rte_eth_dev_get_addr_by_port
  |- removed API rte_eth_dev_get_port_by_addr
  |- removed rte_cryptodev_create_unique_device_name API
  |- moved device naming to EAL

Also, deprecation notice from 16.07 has been removed and release notes for
16.11 added.

+* **Improved device/driver heirarchy and generalized hotplugging**
+
+  Device and driver relationship has been restructured by introducing generic
+  classes. This paves way for having PCI, VDEV and other device types as
+  just instantiated objects rather than classes in themselves. Hotplugging too
+  has been generalized into EAL so that ethernet or crypto devices can use the
+  common infrastructure.
+
+  * removed ``pmd_type`` as way of segragation of devices
+  * moved ``numa_node`` and ``devargs`` into ``rte_driver`` from
+    ``rte_pci_driver``. These can now be used by any instantiated object of
+    ``rte_driver``.
+  * added ``rte_device`` class and all PCI and VDEV devices inherit from it
+  * renamed devinit/devuninit handlers to probe/remove to make it more
+    semantically correct with respect to device<=>driver relationship
+  * moved hotplugging support to EAL. Hereafter, PCI and vdev can use the
+    APIs ``rte_eal_dev_attach`` and ``rte_eal_dev_detach``.
+  * helpers and support macros have been renamed to make them more synonymous
+    with their device types
+    (e.g. ``PMD_REGISTER_DRIVER`` => ``DRIVER_REGISTER_PCI``)
+  * Device naming functions have been generalized from ethdev and cryptodev
+    to EAL. ``rte_eal_pci_device_name`` has been introduced for obtaining
+    unique device name from PCI Domain-BDF description.
+  * Virtual device registration APIs have been added: ``rte_eal_vdrv_register``
+    and ``rte_eal_vdrv_unregister``.
