truncating a file opened via open()

[Steven M. Kramer]

I wrote a few routines for non-4.2 machines that mimicked the 4.2
routines.  Ftruncate was one of them.  I probably missed some wierd
conditions (like file descriptors refering to non-reg files, ..., and
errno's), but my ftruncate works OK in a pinch.  I posted the
source to net.sources.
