crypto/aesni_gcm: migrate from MB library to ISA-L

Current Cryptodev AES-NI GCM PMD is implemented using Multi Buffer
Crypto library.This patch reimplement the device using ISA-L Crypto
library: https://github.com/01org/isa-l_crypto.

The migration entailed the following additional support for:
  * GMAC algorithm.
  * 256-bit cipher key.
  * Session-less mode.
  * Out-of place processing
  * Scatter-gatter support for chained mbufs (only out-of place and
    destination mbuf must be contiguous)

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.

cryptodev: remove unused digest-appended feature

efd: new Elastic Flow Distributor library

Elastic Flow Distributor (EFD) is a distributor library that uses
perfect hashing to determine a target/value for a given incoming flow key.
It has the following advantages:

- First, because it uses perfect hashing, it does not store
  the key itself and hence lookup performance is not dependent
  on the key size.

- Second, the target/value can be any arbitrary value hence
  the system designer and/or operator can better optimize service rates
  and inter-cluster network traffic locating.

- Third, since the storage requirement is much smaller than a hash-based
  flow table (i.e. better fit for CPU cache), EFD can scale to
  millions of flow keys.
  Finally, with current optimized library implementation performance
  is fully scalable with number of CPU cores.

eal: introduce I/O device memory read/write operations

This commit introduces 8-bit, 16-bit, 32bit, 64bit I/O device
memory read/write operations along with the relaxed versions.

The weakly-ordered machine like ARM needs additional I/O barrier for
device memory read/write access over PCI bus.
By introducing the eal abstraction for I/O device memory read/write access,
The drivers can access I/O device memory in architecture agnostic manner.

The relaxed version does not have additional I/O memory barrier, useful in
accessing the device registers of integrated controllers which
implicitly strongly ordered with respect to memory access.
