[3/5] devtools/cocci: create safer version of strlcpy script
Checks
Commit Message
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.
