bcd7e3e8e6 crypto/qat: handle mixed hash-cipher requests on GEN3
This patch implements handling mixed encrypted digest hash-cipher
requests (e.g. SNOW3G + ZUC or ZUC + AES CTR) possible when running
on GEN3 QAT. Such algorithm combinations are not supported on
GEN1/GEN2 hardware.

026f21c0b9 common/qat: support dual threads for enqueue/dequeue
Remove the limitation whereby enqueue and dequeue must be
done in same thread.
The inflight calculation is reworked to be thread-safe for 2
threads - note this is not general multi-thread support, i.e
all enqueues to a qp must still be done in one thread and
all dequeues must be done in one thread, but enqueues and
dequeues may be in separate threads.
Documentation updated.

1be7855d77 eal: add wait until equal API
The rte_wait_until_equal_xx APIs abstract the functionality of
'polling for a memory location to become equal to a given value'.

Add the RTE_ARM_USE_WFE configuration entry for aarch64, disabled
by default. When it is enabled, the above APIs will call WFE instruction
to save CPU cycles and power.

From a VM, when calling this API on aarch64, it may trap in and out to
release vCPUs whereas cause high exit latency. Since kernel 4.18.20 an
adaptive trapping mechanism is introduced to balance the latency and
workload.

0c4155c7b5 event/dsw: avoid credit leak on oversized enqueue bursts
If an application issues rte_event_enqueue_new_burst() or
rte_event_enqueue_forward_burst() call with a burst of events longer
than the configured max enqueue burst size, DSW allocates credits not
only for events actually enqueued, but for the complete burst. If this
process is repeated, enough credits will have leaked to cause the
event device to backpressure (i.e. disallow) any new enqueue
operations.

In addition, the port-level enqueue xstats will log the wrong number
of events enqueued for oversized enqueues.

This patch makes DSW gracefully handle oversized enqueue bursts.

30a0df64aa test/common: fix log2 check
We recently started to get random failures on the common_autotest ut with
clang on Ubuntu 16.04.6.

Example: https://travis-ci.com/DPDK/dpdk/jobs/263177424

Wrong rte_log2_u64(0) val 0, expected ffffffff
Test Failed

The ut passes 0 to log2() to get an expected value.

Quoting log2 / log(3) manual:
If x is zero, then a pole error occurs, and the functions return
-HUGE_VAL, -HUGE_VALF, or -HUGE_VALL, respectively.

rte_log2_uXX helpers handle 0 as a special value and return 0.
Let's have dedicated tests for this case.

f26c2b39b2 build: fix soname info for 19.11 compatibility
The soname for each stable ABI version should be just the ABI version major
number without the minor number. Unfortunately both major and minor were
used causing version 20.1 to be incompatible with 20.0.

This patch fixes the issue by switching from 2-part to 3-part ABI version
numbers so that we can keep 20.0 as soname and using the final digits to
identify the 20.x releases which are ABI compatible. This requires changes
to both make and meson builds to handle the three-digit version and shrink
it to 2-digit for soname.

The final fix needed in this patch is to adjust the library version number
for the ethtool example library, which needs to be upped to 2-digits, as
external libraries using the DPDK build system also use the logic in this
file.

924e55fb34 devtools: fix debug build test
When testing build with +debug options, the statistics are enabled.
It was wrongly matching CONFIG_RTE_IBVERBS_LINK_STATIC.
The pattern is fixed to match only statistics config options.

c3e89f69fa net/mlx: fix build with clang 9
This rewrites the MKSTR macro appending an empty string to its arguments
to resolve build failures similar to:

  drivers/net/mlx4/mlx4.c:461:14: fatal error: format string is not a
  string literal [-Wformat-nonliteral]
          MKSTR(path, "%s/device/uevent", device->ibdev_path);

  drivers/net/mlx4/mlx4_utils.h:82:30: note: expanded from macro 'MKSTR'
          char name[snprintf(NULL, 0, __VA_ARGS__) + 1]; \

  drivers/net/mlx5/mlx5_stats.c:144:15: fatal error: format string is not a
  string literal [-Wformat-nonliteral]
  	MKSTR(path, "%s/ports/%d/hw_counters/%s",

  drivers/net/mlx5/mlx5_utils.h:149:30: note: expanded from macro 'MKSTR'
  	char name[snprintf(NULL, 0, __VA_ARGS__) + 1]; \

The errors reproduce with clang version 9.0.0, and the release notes
don't mention what could have caused them.

878f99d114 doc: fix build with python 3.8
After upgrading to python-3.8.0, a syntax mismatch is revealed:

doc/guides/conf.py:240: SyntaxWarning: "is not" with a literal.
    Did you mean "!="?
    if value is not '':

Removing "is not ''" seems the right thing to do.

A patch may also be needed in the RTD theme package:

(not included in release 0.4.3)
