Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

xargs(1) is WARNS=6 clean.

Tested on: i386, sparc64

Take __FreeBSD_version into account when BOOTSTRAPPING.

xargs.c,v 1.33 broke the upgrade path from old versions of 4.x and 5.0.

Bump WARNS to 4.

After 3 months...

Merge xargs(1) with that of xMach.

Bring in xargs(1) changes to add -L and -I as per the Single Unix Specification
version 3. Proper exit status numbers are implemented, and the manual page has
been updated to reflect reality.

The code has been ANSIfied, and a new file has been added to xargs(1) to do the
substring substitution as SUSv3 requires.

Traditional behaviour should not be affected, use of -J should be deprecated
in favor of the more portable -I (though -J has been left, for now).
