  Correct double-free situation in manager output processing.

  The process_output() function calls ast_str_append() and xml_translate() on its
  'out' parameter, which is a pointer to an ast_str buffer. If either of these
  functions need to reallocate the ast_str so it will have more space, they will
  free the existing buffer and allocate a new one, returning the address of the
  new one. However, because process_output only receives a pointer to the ast_str,
  not a pointer to its caller's variable holding the pointer, if the original
  ast_str is freed, the caller will not know, and will continue to use it (and
  later attempt to free it).
