pif: Limit pif names to 128 bytes

All current pif names are quite short, and we expect them to remain short
when/if we allow arbitrary pifs.  However, because of the structure of
the current code we don't enforce any limit on the length.

This will become more important with dynamic configuration updates, so
start enforcing a length limit.  Specifically we allow pif names to be up
to 128 bytes (PIF_NAME_SIZE), including the terminating \0.  This is
more or less arbitrary, but seems like it should be comfortably enough for
all the cases we have in mind.
