argv0 - run a program with a specified 0th argument

argv0 runs the program stored as realname on disk, with the given arguments.  It sets the 0th argument of
       the program to zero.

       For example,

            argv0 /bin/csh -bin/csh

       runs  /bin/csh  with  a  0th  argument  of  -bin/csh.   csh  will  think  it  is a login shell and behave
       accordingly.

       argv0 can be used to run some inetd wrappers under tcpserver.
