fixed minor memory leaks of per-state data in teco_machine_main_t

* These were leaked e.g. in case of end-of-macro errors,
  but also in case of syntax highlighting (teco_lexer_style()).
  I considered to solve this by overwriting more of the end_of_macro_cb,
  but it didn't turn out to be trivial always.
* Considering that the union in teco_machine_main_t saved only 3 machine words
  of memory, I decided to sacrifice those for more robust memory management.
* teco_machine_qregspec_t cannot be directly embedded into teco_machine_main_t
  due to recursive dependencies with teco_machine_stringbuilding_t.
  It could now and should perhaps be allocated only once in teco_machine_main_init(),
  but it would require more refactoring.
