Fix a race condition: do not unlink(2) a file and then open(2) it
with O_CREAT|O_EXCL; instead, always create it with a temporary name,
then rename(2) it into place atomically. For example, the race caused
failures in parallel builds that (foolishly) install the same file twice.
This patch makes the -S option a no-op,
making install(1) always behave like -S used to.
Based on a minimally different patch
from Lauri Tirkkonen <lotheac at iki dot fi>,
and including a manual page tweak from deraadt@.
OK deraadt@; "seems the right thing to do" tedu@.
