Hi, This series used to be just one patch in [v2] but I've split it into two separate patches.
The motivation behind this series is that strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. In cases where we expect the destination buffer to be NUL-terminated let's opt for strscpy() as this guarantees NUL-termination. Other cases are just simple byte copies with pre-determined bounds; for these let's use plain-ol' memcpy(). Each change is detailed in its accompanying patch message.
