The meson.build files for building the kernel modules directory could
be improved now that it is extracted from the EAL. For example, no
global processing is necessary inside the kernel folder, just need to
subdir to the appropriate bsd or linux folder to do the actual work.
To avoid potential race conditions with the BSD module builds when
the kernel build system is creating the dev_if.h and other files,
we serialize the kernel module builds (all 2 of them!) by setting
up each module to depend on all the previous.

Some DPDK applications wrongly assume these requirements:
- no hotplug, i.e. ports are never detached
- all allocated ports are available to the application
Such application iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.

The initial objective of
commit d9f0d3a1ffd4 ("ring: remove split cacheline build setting")
was to add an empty cache line between the producer and consumer
data (on platform with cache line size = 64B), preventing from
having them on adjacent cache lines.
Following discussion on the mailing list, it appears that this
also imposes an alignment constraint that is not required.
This patch removes the extra alignment constraint and adds the
empty cache lines using padding fields in the structure. The
size of rte_ring structure and the offset of the fields remain
the same on platforms with cache line size = 64B:
rte_ring = 384
rte_ring.name = 0
rte_ring.flags = 32
rte_ring.memzone = 40
rte_ring.size = 48
rte_ring.mask = 52
rte_ring.prod = 128
rte_ring.cons = 256
But it has an impact on platform where cache line size is 128B:
rte_ring = 384 -> 768
rte_ring.name = 0
rte_ring.flags = 32
rte_ring.memzone = 40
rte_ring.size = 48
rte_ring.mask = 52
rte_ring.prod = 128 -> 256
rte_ring.cons = 256 -> 512

While debugging startup issues encountered with Clang (see "eal: fix
undefined behavior in fbarray"), I noticed that fbarray stores indices,
sizes and masks on signed integers involved in bitwise operations.
Such operations almost invariably cause undefined behavior with values that
cannot be represented by the result type, as is often the case with
bit-masks and left-shifts.
This patch replaces them with unsigned integers as a safety measure and
promotes a few internal variables to larger types for consistency.

According to GCC documentation [1], the __builtin_clz() family of functions
yield undefined behavior when fed a zero value. There is one instance in
the fbarray code where this can occur.
Clang (at least version 3.8.0-2ubuntu4) seems much more sensitive to this
than GCC and yields random results when compiling optimized code, as shown
below:
#include <stdio.h>
int main(void)
{
volatile unsigned long long moo;
int x;
moo = 0;
x = __builtin_clzll(moo);
printf("%d\n", x);
return 0;
}
$ gcc -O3 -o test test.c && ./test
63
$ clang -O3 -o test test.c && ./test
1742715559
$ clang -O0 -o test test.c && ./test
63
Even 63 can be considered an unexpected result given the number of leading
zeroes should be the full width of the underlying type, i.e. 64.
In practice it causes find_next_n() to sometimes return negative values
interpreted as errors by caller functions, which prevents DPDK applications
from starting due to inability to find free memory segments:
