Currently, in order to get the name of a crypto device,
a user needs to access to it using the crypto device structure.
It is a better practise to have a function to retrieve this
name, given a device id.

Change crypto device's session management to make it
device independent and simplify architecture when session
is intended to be used on more than one device.
Sessions private data is agnostic to underlying device
by adding an indirection in the sessions private data
using the crypto driver identifier.
A single session can contain indirections to multiple device types.
New function rte_cryptodev_sym_session_init has been created,
to initialize the driver private session data per driver to be
used on a same session, and rte_cryptodev_sym_session_clear
to clear this data before calling rte_cryptodev_sym_session_free.

Changes device type identification to be based on a unique
driver id replacing the current device type enumeration, which needed
library changes every time a new crypto driver was added.
The driver id is assigned dynamically during driver registration using
the new macro RTE_PMD_REGISTER_CRYPTO_DRIVER which returns a unique
uint8_t identifier for that driver. New APIs are also introduced
to allow retrieval of the driver id using the driver name.

HW based crypto drivers may only support limited number of
sessions per queue pair. This requires support for attaching
sessions to specific queue pair. New APIs are introduced to
attach/detach a session with/from a particular queue pair.
These are optional APIs.
Application can call attach API after creating a session
and can call detach API before deleting a session.
Application needs to check if max_nb_sessions_per_qp > 0,
then it should call the attach API.
max_nb_sessions_per_qp = 0 means infinite sessions per qp

This patch adds a user defined name initializing parameter to cryptodev
library.
Originally, for software cryptodev PMD, the vdev name parameter is
treated as the driver identifier, and will create an unique name for each
device automatically, which is not necessarily as same as the vdev
parameter.
This patch allows the user to either create a unique name for his software
cryptodev, or by default, let the system creates a unique one. This should
help the user managing the created cryptodevs easily.
Examples:
CLI command fragment 1: --vdev "crypto_aesni_gcm_pmd"
The above command will result in creating a AESNI-GCM PMD with name of
"crypto_aesni_gcm_X", where postfix X is the number assigned by the system,
starting from 0. This fragment can be placed in the same CLI command
multiple times, resulting the postfixs incremented by one for each new
device.
CLI command fragment 2: --vdev "crypto_aesni_gcm_pmd,name=gcm1"
The above command will result in creating a AESNI-GCM PMD with name of
"gcm1". This fragment can be placed in the same CLI command multiple
times, as long as each having a unique name value.

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.
Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.
Update documentation for replacing an example referring to
PMD_REGISTER_DRIVER.

This patch add a mechanism for discovery of crypto device features and supported
crypto operations and algorithms. It also provides a method for a crypto PMD to
publish any data range limitations it may have for the operations and algorithms
it supports.
The parameter feature_flags added to rte_cryptodev struct is used to capture
features such as operations supported (symmetric crypto, operation chaining etc)
as well parameter such as whether the device is hardware accelerated or uses
SIMD instructions.
The capabilities parameter allows a PMD to define an array of supported operations
with any limitation which that implementation may have.
Finally the rte_cryptodev_info struct has been extended to allow retrieval of
these parameter using the existing rte_cryptodev_info_get() API.

This patch modifies the crypto burst enqueue/dequeue APIs to operate on bursts
rte_crypto_op's rather than the current implementation which operates on
rte_mbuf bursts, this simplifies the burst processing in the crypto PMDs and the
use of crypto operations in general, including new functions for managing
rte_crypto_op pools.
These changes continues the separation of the symmetric operation parameters
from the more general operation parameters, which will simplify the integration
of asymmetric crypto operations in the future.
PMDs, unit tests and sample applications are also modified to work with the
modified and new API.
