pervasive: tame remaining calls to strncpy()
- strncpy is rarely the right thing to do
- for pure NUL-padding, strncpy is fine. But that is rarely used in C
and when it is used, code is often buggy
- for pure NUL-termination, jam_str is best.
- for safety, we NUL-terminate everything that is NUL-padded. The
only problem is that the longest representable strings are one
character shorter.
- too few datastructures document whether NUL-padding or
NUL-termination is required so we do both. For example,
if I remember correctly, BSD requires network interface
names to be NUL-padded and Linux requires NUL-termination.
