c649f0b4f5 build: add libatomic dependency for 32-bit clang
When compiling with clang on 32-bit platforms, we are missing copies
of 64-bit atomic functions. We can solve this by linking against
libatomic for the drivers and libs which need those atomic ops.

6723c0fc72 replace snprintf with strlcpy
Do a global replace of snprintf(..."%s",...) with strlcpy, adding in the
rte_string_fns.h header if needed.  The function changes in this patch were
auto-generated via command:

  spatch --sp-file devtools/cocci/strlcpy.cocci --dir . --in-place

and then the files edited using awk to add in the missing header:

  gawk -i inplace '/include <rte_/ && ! seen { \
  	print "#include <rte_string_fns.h>"; seen=1} {print}'

f8e9989606 remove useless constructor headers
A constructor is usually declared with RTE_INIT* macros.
As it is a static function, no need to declare before its definition.
The macro is used directly in the function definition.

d593a8177f eventdev: add device stop flush callback
When an event device is stopped, it drains all event queues and ports.
These events may contain pointers, so to prevent memory leaks eventdev now
supports a user-provided flush callback that is called during the queue
drain process. This callback is stored in process memory, so the callback
must be registered by any process that may call rte_event_dev_stop().

This commit also clarifies the behavior of rte_event_dev_stop().

This follows this mailing list discussion:

b770f952de event/opdl: fix atomic queue race condition
If application link one atomic queue to multiple ports,
and each worker core update flow_id, there will have a
chance to hit race condition issue and lead to double processing
same event. This fix solve the problem and eliminate
the race condition issue.

3c7f3dcfb0 event/opdl: add PMD main body and helper function
This commit adds a OPDL implementation of the eventdev API. The
implementation here is intended to enable the community to use
the OPDL infrastructure under eventdev API.

The main components of the implementation is three files:
  - opdl_evdev.c              Creation, configuration, etc
  - opdl_evdev_xstats.c       helper function to support stats collection
  - opdl_evdev.h              include the main data structure of opdl
                              device and all the function prototype
                              need to be exposed to support eventdev API.

  - opdl_evdev_init.c         implement all initailization helper function

This commit only adds the implementation, no existing DPDK files
are modified.

4236ce9bf5 event/opdl: add OPDL ring infrastructure library
OPDL ring is the core infrastructure of OPDL PMD. OPDL ring library
provide the core data structure and core helper function set. The Ring
implements a single ring multi-port/stage pipelined packet distribution
mechanism. This mechanism has the following characteristics:

• No multiple queue cost, therefore, latency is significant reduced.
• Fixed dependencies between queue/ports is more suitable for complex.
  fixed pipelines of stateless packet processing (static pipeline).
• Has decentralized distribution (no scheduling core).
• Packets remain in order (no reorder core(s)).
* Update build system to enable compilation.
