viced: If platform supports setting a thread title, do so
Some pthread libraries support setting a name or title for individual
threads (analogous to setproctitle() for processes). This can be useful
for debugging and is sometimes published for use by utilities like ps
(again like setproctitle() for processes). The two most common variants
of this have the same signature with slightly different function names.
If either one is present, use it in viced (which already assigns a thread
name when compiled for LWP but ignores it in pthreads compilations).
