This patch adds a new API "rte_cryptodev_sym_session_pool_create()" to
cryptodev library. All applications are required to use this API to
create sym session mempool as it adds private data and nb_drivers
information to the mempool private data.

- define asym op type in rte_crypto_op_type and associated

- define asym session and associated session APIs

If PMD shows in its feature flag that it supports both sym and

2d349f6034 cryptodev: rename experimental private data APIs
The name private_data is confusing in these APIs:
rte_cryptodev_sym_session_set_private_data()
rte_cryptodev_sym_session_get_private_data()
It refers to data added at the end of the session hdr for
use by the application.
The session already contains sess_private_data[index]
which is used to store private pmd data and most references to private
data refer to that.
e.g. external apis
rte_cryptodev_sym_get_private_session_size() and internal
set/get_session_private_data() refer to sess_private_data[].

So rename to user_data, i.e.
rte_cryptodev_sym_session_set_user_data()
rte_cryptodev_sym_session_get_user_data()

Refers to changes introduced here:

a106fcce2c cryptodev: rename functions to get session size
rte_cryptodev_get_header_session_size() and
rte_cryptodev_get_private_session_size() functions are
targeting symmetric sessions.

With the future addition of asymmetric operations,
these functions need to be renamed from *cryptodev_*_session_*
to *cryptodev_sym_*_session_* to be symmetric specific.

The two original functions are marked as deprecated
and will be removed in 18.08, so applications can still
use the functions in 18.05.

2d96371fbd cryptodev: support session private data setting
The application may want to store private data along with the
rte_cryptodev that is transparent to the rte_cryptodev layer.
For e.g., If an eventdev based application is submitting a
rte_cryptodev_sym_session operation and wants to indicate event
information required to construct a new event that will be
enqueued to eventdev after completion of the rte_cryptodev_sym_session
operation. This patch provides a mechanism for the application
to associate this information with the rte_cryptodev_sym_session session.
The application can set the private data using
rte_cryptodev_sym_session_set_private_data() and retrieve it using
rte_cryptodev_sym_session_get_private_data().

b3bbd9e5f2 cryptodev: support device independent sessions
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.

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

d803b4439d cryptodev: add user defined name for vdev
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.

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

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.
