Note that this now highlights weaknesses in the label measuring code

Convert all msvcrt locks over to use _lock and _unlock.
Explicitly make msvcrt compile with multithreaded option.
Fix flag handling in _sopen. Add W->A call for new _swopen.

- Allocate and free the temporary copy required for DT_MODIFYSTRING
  rather than using a fixed size stack array.
- Introduce lastline into the main loop; it simplifies the code and we
  are going to need it.
