The existing code used to search for module files via modinfo has
several corner cases which can result in it failing where it should be
successful.
The call to lower() would cause results returned by 'modinfo' to be
forced to lowercase, results which were subsequently passed to
exists() which is case sensitive. This was most likely done to capture
all variants of failure strings modinfo might return
(ie. ERROR/Error/error/...) without thought negative effect to the
later call to exists(). For many this is a nonissue but if the module
path included non-lowercase alpha characters, something which is
easily possible with a non-lowercase kernel-extraversion string, this
would cause an issue.
We could move the call to lower() to the check for "error" but this
still leaves possible corner cases, for modules or module paths with
'error' in them.
Instead we will prevent modinfo's stderr from being used as a "good
value" for path, meaning we either get a valid path from modinfo, or
nothing at all. This removes all corner cases.
Ultimately these preliminary checks are unnecessary as exists() will
only return True if it is passed a valid path, passing it modinfo's
stderr would fail. In keeping with the original code, however, we do
some preliminary checks, but we are now free of corner cases.

doc: add description for modified xstats API
Documentation change for new extended statistics API functions.
The old API only allows retrieval of *all* of the NIC statistics
at once. Given this requires a MMIO read PCI transaction per statistic
it is an inefficient way of retrieving just a few key statistics.
Often a monitoring agent only has an interest in a few key statistics,
and the old API forces wasting CPU time and PCIe bandwidth in retrieving
*all* statistics; even those that the application didn't explicitly
show an interest in.
The new, more flexible API allow retrieval of statistics per ID.
If a PMD wishes, it can be implemented to read just the required
NIC registers. As a result, the monitoring application no longer wastes
PCIe bandwidth and CPU time.

The problem is that the difference between this value and the ring size

if the descriptors are not replenished quick enough, queue might
not be busy, but the app would think that it is, because 96th descriptor

Also:
- Add C++ awareness to rte_vhost.h for consistency with rte_eth_vhost.h.
- Move Linux includes into C++ block to prevent linking issues with
exported symbols.
- Update check-includes.sh following the removal of rte_virtio_net.h.
Finally, update check-includes.sh to ignore rte_vhost.h and rte_eth_vhost.h
from now on since the Linux headers they depend on are not clean enough:

C++ does not support the C99-style designated initializers used in this
file for the default item masks. While the resulting symbols are primarily
useful to PMDs (written in C), they are exposed as part of the public API
for documentation purposes and to assist application writers.
Considering that:
- using pre-C99 initialization style for compatibility with C++ would
render them difficult to understand (all struct members must be
initialized)
- using both initialization styles would be needlessly verbose
- not exposing them at all would defeat their purpose
- applications do not normally need these symbols at run time
This commit hides these symbols from C++ applications. Specific C++
initializers will be added later if necessary.

The RTE_FUNC_*_RET() and RTE_PROC_*_RET() macro definitions in rte_dev.h
require RTE_PMD_DEBUG_TRACE(). This macro is defined as needed by users of
rte_dev.h since its value depends on their own debug settings.
It may be defined multiple times as a result when including files from
various components simultaneously. Worse, these redefinitions may be
inconsistent. This causes the following compilation errors:

This commit moves the RTE_PMD_DEBUG_TRACE() definition to rte_dev.h where
it is enabled consistently depending on global configuration settings and
removes redundant definitions.
Also when disabled, RTE_PMD_DEBUG_TRACE() is now defined as (void)0 to
avoid empty statements warnings if used outside { } blocks.

config: make AVX and AVX512 configurable
Making AVX and AVX512 configurable is useful for performance and power
testing.
The similar kernel patch at https://patchwork.kernel.org/patch/9618883/.
AVX512 support like in rte_memcpy has been in DPDK since 16.04, but it's
still unproven in rich use cases in hardware. Therefore it's marked as
experimental for now, will enable it after enough field test and possible
optimization.

config: set cache line as 128B for generic arm64
armv8 implementations may have 64B or 128B cache line.
Setting to the maximum available cache line size in generic config to
address minimum DMA alignment across all arm64 implementations.
Increasing the cacheline size has no negative impact to cache invalidation
on systems with a smaller cache line.
The need for the minimum DMA alignment has impact on functional aspects
of the platform so default config should cater the functional aspects.
There is an impact on memory usage with this scheme, but that's not too
important for the single image arm64 distribution use case.
The arm64 linux kernel followed the similar approach for single
arm64 image use case.
