735155ee3b devtools: add cocci script to rename mbuf offload flags
The mbuf offload flags do not match the DPDK namespace (they are not
prefixed by RTE_). This coccinelle script is used in the next commit to
do the replacement in the code.

A draft script was initially submitted [1] in commit d7595795b7 ("doc:
announce renaming of mbuf offload flags"), but dropped by mistake at
commit.

277b6e7ef4 devtools/cocci: create safer version of strlcpy script
The existing cocci script for coccinelle replaces all matching instances
of snprintf() with strlcpy() without regards to header inclusion. To allow
changes without build errors, we create a safer version of this script
that only makes changes when the rte_string_fns.h header is already
included.

a5df16c1f7 devtools/cocci: make strlcpy replacement smarter
The original coccinelle script worked by replacing instances of
snprintf(.."%s",...) with strlcpy(), but only where the source and dest
parameters were plain identifiers. Allowing expressions for those params
opens up a wide range of other possible changes.

5364de644a eal: support strlcpy function
The strncpy function is error prone for doing "safe" string copies, so
we generally try to use "snprintf" instead in the code. The function
"strlcpy" is a better alternative, since it better conveys the
intention of the programmer, and doesn't suffer from the non-null
terminating behaviour of it's n'ed brethern.

The downside of this function is that it is not available by default
on linux, though standard in the BSD's. It is available on most
distros by installing "libbsd" package.

This patch therefore provides the following in rte_string_fns.h to ensure
that strlcpy is available there:
* for BSD, include string.h as normal
* if RTE_USE_LIBBSD is set, include <bsd/string.h>
* if not set, fallback to snprintf for strlcpy

Using make build system, the RTE_USE_LIBBSD is a hard-coded value to "n",
but when using meson, it's automatically set based on what is available
on the platform.

9a98f50e89 scripts: move to devtools
The remaining scripts in the scripts/ directory are only useful
to developers. That's why devtools/ is a better name.
