These callbacks are set using the following:

  breakpoint command add -s lua -o "print('hello world!')"

The user supplied script is executed as:

  function (frame, bp_loc, ...)
     <body>
  end

So the local variables 'frame', 'bp_loc' and vararg are all accessible.
Any global variables declared will persist in the Lua interpreter.
A user should never hold 'frame' and 'bp_loc' in a global variable as
these userdatas are context dependent.
