(Frodo) Unicode transition

Note: this commit breaks psiconv. The programs in the extra directory should
work properly.

  * Change all datastructures to use unicode for character encodings
  * Added psiconv_error function
  * Called psiconv_error at places where a warning was stupid
  * Added psiconv_progress in all generate functions
  * Added lev parameter to all generate functions
  * Removed general.h from CVS (we have general.h.in, after all)
  * Probably other stuff I forgot
