src/usr.bin/xargs, branch release/5.2.1

- Use _PATH_TTY and _PATH_DEVNULL macros.

- Don't fail if we can't open /dev/null since this can happen if xargs is jail'ed or chroot'ed. These fixes were submitted by Todd Miller from the OpenBSD project. There was one problem in those fixes that broke -o, which is corrected here and should be committed to the OpenBSD repo by Todd soon. MFC in: 3 days

Use waitpid, instead of wait3, which is more portable.

Migrate to a new way of dealing with building from old revisions of

FreeBSD. This method attempts to centralize all the necessary hacks or work arounds in one of two places in the tree (src/Makefile.inc1 and src/tools/build). We build a small compatibility library (libbuild.a) as well as selectively installing necessary include files. We then include this directory when building host binaries. This removes all the past release compatibilty hacks from various places in the tree. We still build on tip of stable and current. I will work with those that want to support more, although I anticipate it will just work. Many thanks to ru@, obrien@ and jhb@ for providing valuable input at various stage of implementation, as well as for working together to positively effect a change for the better.

Simplify compatibility ifdef.

the child process, before executing the command. This is very useful when you do stuff like ``find ... | xargs interactive_application''. Without -o, the application would inherit the pipe as its stdin, and you thus lose any control over it. This flag has been carefully chosen to not conflit with other options of other xargs utilities like GNU xargs. Reviewed by: jmallett
