Sync with FreeBSD's xargs plus some fixes by me. This makes us POSIX-compliant and adds some useful extensions. Most of the work in FreeBSD was done by jmallett.
Remove the advertising clause in the UCB license which Berkeley rescinded 22 July 1999. Proofed by myself and Theo.
remove duplicate includes
Delete support for LC_MESSAGES which we shall never implement. This nicely simplifies the code, deleting three header inclusions and calls to various complicated library functions.
Suppress a spurious empty arg at EOF w/ "find -0" caused by the last commit.
