  * Split requireProgram into two different functions
  Now requireProgram doesn't take a version range and does not check
  the program version (indeed it doesn't need to have one). The new
  function requireProgramVersion takes a required program version
  range and returns the program version. Also update callers.
  Also fixes the check that GHC has a version number.
