Remove long text being cropped/wrapped to standard 80x24 on launch.

To be more specific, now tty creation is delayed until X window is
actually mapped; last ConfigureNotify before mapping determines
initial tty size.
Please report problems if there are any.

 * fix rows and column definition in fixed geometry
 * fix -e handling
 * remove DEC test sequence when appropriate
-* When some application outputting long text is run in the shell init scripts,
-  then this text might be stripped to the standard 80x25 due to st running the
-  virtual terminal at first priority. Maybe the vt initialisation could be
-  moved somewhere after knowing the right window size.
