vangyzen abbf63d36b thr_set_name(): silently truncate the given name as needed
Instead of failing with ENAMETOOLONG, which is swallowed by
pthread_set_name_np() anyway, truncate the given name to MAXCOMLEN+1
bytes.  This is more likely what the user wants, and saves the
caller from truncating it before the call (which was the only
recourse).

Polish pthread_set_name_np(3) and add a .Xr to thr_set_name(2)
so the user might find the documentation for this behavior.
