8e35792c53 eal: remove dead code on NUMA node detection
RTE_EAL_ALLOW_INV_SOCKET_ID had been introduced and documented as used
with xen dom0 support (dropped for some time now).

Closely looking at this, the code was changed later and ensures that the
socket id is in the [0..RTE_MAX_NUMA_NODES] range anyway.

Let's drop this dead code and the build option with it.

ed5d3d5cdb eal/linux: restore specific hugepage ordering for ppc
An ifdef present in eal_memory.c references "RTE_ARCH_PPC64" when
it should actually use "RTE_ARCH_PPC_64".  Simple testing revealed
that both the PPC_64 and non-PPC_64 versions of the code involved
work, but the PPC_64 version of the code is retained to be
consistent with other instances in the same file where mmapped
memory is accessed in reverse order on Power platforms.

524a0d5d66 build: enable extra warnings with meson
While meson always adds -Wall flag to C compiles, the make build adds extra
warning flags that are not present in the meson build. This addresses that
shortcoming by adding additional warning flags to our builds. The one
omission is the -Wcast-align flag, which though present in make gcc builds,
gives a lot of warnings/errors when used with clang.

The removed warning "-Wunused-parameter" is covered by the "-Wextra"
parameter so is unnecessary.

7e2c3e17fe eal/arm64: add 128-bit atomic compare exchange
This patch adds the implementation of the 128-bit atomic compare
exchange API on aarch64. Using 64-bit 'ldxp/stxp' instructions
can perform this operation. Moreover, on the LSE atomic extension
accelerated platforms, it is implemented by 'casp' instructions for
better performance.

Since the '__ARM_FEATURE_ATOMICS' flag only supports GCC-9, this
patch adds a new config flag 'RTE_ARM_FEATURE_ATOMICS' to enable
the 'cas' version on older version compilers.
For octeontx2, we make sure that the lse (and other) extensions are
enabled even if the compiler does not know of the octeontx2 target
cpu.

Since direct x0 register used in the code and cas_op_name() and
rte_atomic128_cmp_exchange() is inline function, based on parent
function load, it may corrupt x0 register aka break aarch64 ABI.
Define CAS operations as rte_noinline functions to avoid an ABI
break [1].

Some number of these entries also share the cache line with
the internal_flags member of struct rte_service_spec_impl,
hence this false sharing also makes the service_valid() check
expensive.

Eliminate false sharing by moving the active_on_lcore array to
a per-core data structure. The array is now indexed by service id.

c1077933d4 timer: remove useless check on x86 TSC reliability
This code was added 7+ years ago in
commit fb022b85ba ("timer: check TSC reliability")
presumably when variant TSCs were still somewhat common.

But this code doesn't do anything except print a warning,
and the warning doesn't give any kind of advice to the user,
so let's just remove it.

While the warning has no functional meaning, the /proc/cpuinfo
parsing consumes a non-trivial amount of time which is especially
noticeable in secondary processes.
On my test system, it consumes 21ms out of the 66ms total execution
time for rte_eal_init() in a secondary process.

72e69d801b eal/ppc: fix 64-bit atomic exchange operation
The rte_atomic64_exchange operation for ppc_64 incorrectly linked
back to a 32 bit generic operation (__atomic_exchange_4) rather than
the 64 bit generic operation (__atomic_exchange_8).  As a result,
applications that used rte_eth_link_get_nowait() would only receive
the link speed, they would not receive the link state, link duplex,
or link autoneg properties.

c3a90c381d mbuf: add a copy routine
This is a commonly used operation that surprisingly the
DPDK has not supported. The new rte_pktmbuf_copy does a
deep copy of packet. This is a complete copy including
meta-data.

It handles the case where the source mbuf comes from a pool
with larger data area than the destination pool. The routine
also has options for skipping data, or truncating at a fixed
length.

This patch also introduces internal inline to copy the
metadata fields of mbuf.

Add a test for this new function, based of the clone tests.
