conf2: debugged a lot

- closing_brace() confused current operation with the one on the stack a lot
- get_word() fix when recognizing = in the parameter name
- split_line() totally rewritten to 2 nice procedures: get_token() and
  split_command()
- #include back to include, otherwise it would be a comment
- local fastbufs in parse_fastbuf()

- the test file updated accordingly
