This patch replaces ctty constants with more descriptive macros
(CTTY_UNINITIALIZED and CTTY_RELEASED) rather than -1 and -2 as
well as checking sign with CTTY_IS_VALID().

Previously, the console device could not be accessed from other terminals.
Due to this limitation, GNU screen and tmux cannot be opened in console.
With this patch, console device can be accessed from other TTYs, such as
other consoles or ptys. Thanks to this patch, screen and tmux get working
in console.

- Previously, we have two tty.cc, one is winsup/cygwin/tty.cc and
the other is winsup/cygwin/fhandler/tty.cc. This is somewhat
confusing. This patch renames fhandler/tty.cc to fhandler/pty.cc.
