Use of strtok() in dpdk code

[Isaac Boukris]

Hello,

I was debugging a crash resulting from strtok() returning NULL
unexpectedly (string still had tokens and delimiters), and the only
explanation I could come up with was that strtok is thread-unsafe and
another thread could have been calling it at the same time, and so I
changed it to use strtok_r().

That said, the only other possible use of strtok() that I could find
was in the dpdk code (telemetry), which brings me to my question,
should we consider changing all occurrences to strtok_r() or am I
missing something? there seem to be quite some in non-initialization
code.

Thanks!
