src/bin/realpath, branch releng/8.4

Enhance realpath(1) in a number of ways:

2008-03-09T12:46:39Z

- Allow realpath to accept multiple paths on the command line. - Add -q to suppress warnings if some paths can't be processed, and use getopt(3) to process flags. - Print the path being requested rather than a possibly partially processed path when a failure occurs so that you can tell which of several passed paths did fail.
