  Log Message:
  -----------
  [LLDB/Lua] add support for one-liner breakpoint callback

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.
