* fhandler.h (dev_console): add title state variables.
* fhandler.h (dev_console): add cursor end-of-buffer variables.

* fhandler_console.cc (macro: srTop, srBottom; char_command): scroll_region is
not relative to window top.

* fhandler_console.cc (get_tty_stuff): save old console title.

* fhandler_console.cc (scroll_screen): renamed variables sr1, sr2 to srScroll,
srClip respectively which is clearer.
* fhandler_console.cc (scroll_screen): added clipping counterpart for top <
clip.top.

* fhandler_console.cc (scroll_screen, char_command, write_normal): more debug
info.

* fhandler_console.cc (char_command): added escape sequence for codepage
switching to enable line drawing characters.

* fhandler_console.cc (write_normal): end of buffer check enables cursor to be
out of range; it better emulates *nix terminal behaviour; ie. it is now
possible to write a single character at right bottom of console buffer without
the console scrolling the buffer.

* fhandler_console.cc (write_normal): cancelled premature optimization, do
always use scroll_screen instead of '\n' sometimes

* fhandler_write.cc (write): if `user' clears title, then don't add `|'
