build: disable experimental API check internally Remove setting ALLOW_EXPERIMENTAL_API individually for each Makefile and meson.build. Instead, enable ALLOW_EXPERIMENTAL_API flag across app, lib and drivers. This changes reduces the clutter across the project while still maintaining the functionality of ALLOW_EXPERIMENTAL_API i.e. warning external applications about experimental API usage.

mk: do not generate LDLIBS from directory dependencies The list of libraries in LDLIBS was generated from the DEPDIRS-xyz variable. This is valid when the subdirectory name match the library name, but it's not always the case, especially for PMDs. The patches removes this feature and explicitly adds the proper libraries in LDLIBS. Some DEPDIRS-xyz variables become useless, remove them.

ring: prepare ring to allow new sync schemes To make these preparations two main things are done: - Change from *single* to *sync_type* to allow different synchronisation schemes to be applied. Mark *single* as deprecated in comments. Add new functions to allow user to query ring sync types. Replace direct access to *single* with appropriate function call. - Move actual rte_ring and related structures definitions into a separate file: <rte_ring_core.h>. It allows to refer contents of <rte_ring_elem.h> from <rte_ring.h> without introducing a circular dependency.

ring: introduce C11 memory model barrier option This patch is to support C11 memory model barrier in librte_ring. There are 2 barrier implementation options in librte_ring (suggested by Jerin). 1. use rte_smp_rmb 2. use load_acquire/store_release(refer to [1]). The reason why providing 2 options is the performance benchmark difference in different arm machines, refer to [2]. CONFIG_RTE_RING_USE_C11_MEM_MODEL is provided, and by default it is "n" on any architectures and only "y" on arm64 so far.

rte_ring_generic.h \
ring: introduce RTS ring mode Introduce relaxed tail sync (RTS) mode for MT ring synchronization. Aim to reduce stall times in case when ring is used on overcommited cpus (multiple active threads on the same cpu). The main difference from original MP/MC algorithm is that tail value is increased not by every thread that finished enqueue/dequeue, but only by the last one. That allows threads to avoid spinning on ring tail value, leaving actual tail value change to the last thread in the update queue.

ring: introduce HTS ring mode Introduce head/tail sync mode for MT ring synchronization. In that mode enqueue/dequeue operation is fully serialized: only one thread at a time is allowed to perform given op.
