d4ad392cbb app/crypto-perf: use separate session mempools
This patch uses the two session mempool approach to crypto perf
application. One mempool is for session header objects, and the other
is for session private data.

3356083a77 app/crypto-perf: fix burst size calculation
This patch fixes segmentation fault in pmd_cyclecount_bench_ops
function in case when state->opts->nb_descriptors is not
natural multiple of burst size.
To reproduce run: dpdk-test-crypto-perf with params:
  --ptest pmd-cyclecount --pmd-cyclecount-delay-ms 5 \
  --devtype crypto_qat --optype cipher-then-auth \
  --cipher-algo aes-cbc --cipher-op encrypt \
  --cipher-key-sz 16 --cipher-iv-sz 16 \
  --auth-algo sha2-256-hmac \
  --auth-op generate --auth-key-sz 64 --digest-sz 32 \
  --total-ops 10000 --burst-sz 255 --buffer-sz 1024 --silent

27c2e74719 app/crypto-perf: support IMIX
Add support for IMIX performance tests, where a distribution
of various packet sizes can be submitted to a crypto
device, testing a closer to a real world scenario.

A sequence of packet sizes, selected randomly from a list of packet
sizes (with "buffer-sz" parameter) with a list of the weights
per packet size (using "imix" parameter), is generated
(the length of this sequence is the same length as the pool,
set with "pool-sz" parameter).

This sequence is used repeteadly for all the crypto
operations submitted to the crypto device (with "--total-ops" parameter).

bf9d6702ec app/crypto-perf: use single mempool
In order to improve memory utilization, a single mempool
is created, containing the crypto operation and mbufs
(one if operation is in-place, two if out-of-place).
This way, a single object is allocated and freed
per operation, reducing the amount of memory in cache,
which improves scalability.

c4f916e332 app/crypto-perf: support multiple queue pairs
Add support for multiple queue pairs, when there are
more logical cores available than crypto devices enabled.
For instance, if there are 4 cores available and
2 crypto devices, each device will have two queue pairs.

This is useful to have multiple logical cores using
a single crypto device, without needing to initialize
a crypto device per core.

083de3eba7 app/crypto-perf: parse segment size
Instead of parsing number of segments, from the command line,
parse segment size, as it is a more usual case to have
the segment size fixed and then different packet sizes
will require different number of segments.

253624f46c app/crypto-perf: refactor common test code
Currently, there is some duplication in all the test types,
in the crypto performance application.

In order to improve maintainability of this code,
and ease future work on it, common functions have been separated
in a different file that gets included in all the tests.

96dfeb609b app/crypto-perf: add new PMD benchmarking mode
This patch adds a new benchmarking mode, which is intended for
microbenchmarking individual parts of the cryptodev framework,
specifically crypto ops alloc-build-free, cryptodev PMD enqueue
and cryptodev PMD dequeue.

It works by first benchmarking crypto operation alloc-build-free
loop (no enqueues/dequeues happening), and then benchmarking
enqueue and dequeue separately, by first completely filling up the
TX queue, and then completely draining the RX queue.

Results are shown as cycle counts per alloc/build/free, PMD enqueue
and PMD dequeue.

One new test mode is added: "pmd-cyclecount"
  (called with --ptest=pmd-cyclecount)

New command-line argument is also added:
  --pmd-cyclecount-delay-ms: this is a pmd-cyclecount-specific parameter
      that controls the delay between enqueue and dequeue. This is
      useful for benchmarking hardware acceleration, as hardware may
      not be able to keep up with enqueued packets. This parameter
      can be increased if there are large amounts of dequeue
      retries.
