fe363dd425 drivers: use vdev registration
All PMD_VDEV drivers can now use rte_vdev_driver instead of the
rte_driver (which is embedded in the rte_vdev_driver).

c830cb2954 drivers: use PCI registration macro
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.

cdfb776ba2 crypto: normalize driver names with macros
Recently reported, the introduction of pmd information exports led to a
breakage of cryptodev unit tests because the test infrastructure relies on the
cryptodev names being available in macros.  This patch fixes the pmd naming to
use the macro names.  Note that the macro names were already pre-stringified,
which won't work as the PMD_REGISTER_DRIVER macro requires the name in both a
processing token and stringified form.  As such the names are defined now as
tokens, and converted where needed to stringified form on demand using RTE_STR.

cb6696d220 drivers: update registration macro usage
Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it.  The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool.  For example:

PMD_REGISTER_DRIVER(ena_driver, ena);

registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";

which pmdinfogen can search for and extract.  The subsequent macro

DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);

creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";

Which allows pmdinfogen to find the pci table of this driver

Using this pattern, we can export arbitrary bits of information.

pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable
later.

4f213197ef mk: fix external dependencies of crypto drivers
When linking drivers as shared libraries, the dependencies need
to be marked as DT_NEEDED entries.

The crypto dependencies (libsso and libIPSec) are static libraries.
To make them linked in the shared PMDs, the code must relocatable:

    - libsso_kasumi.a must be built with KASUMI_CFLAGS=-DKASUMI_C

26c2e4ad5a cryptodev: add capabilities discovery
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.

rte_crypto_op's rather than the current implementation which operates on

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

948fd64bef mk: replace the combined library with a linker script
The physically linked-together combined library has been an increasing
source of problems, as was predicted when library and symbol versioning
was introduced. Replace the complex and fragile construction with a
simple linker script which achieves the same without all the problems,
remove the related kludges from eg mlx drivers.

Since creating the linker script is practically zero cost, remove the
config option and just create it always.

Based on a patch by Sergio Gonzales Monroy, linker script approach
initially suggested by Neil Horman.
