  r330696:
  Add some functional tests for tftpd(8)
  
  tftpd(8) is difficult to test in isolation due to its relationship with
  inetd.  Create a test program that mimics the behavior of tftp(1) and
  inetd(8) and verifies tftpd's response in several different scenarios.
  
  These test cases cover all of the basic TFTP protocol, but not the optional
  parts.
