Throughout, change 'tty_attached' to 'real_tty_attached', for clarity.

Browse Source 
Throughout, change 'OutputStopped' to 'output_stopped', for consistency.
* dtable.cc (stdio_init): Set controlling tty if not set by stdio opens.
* exceptions.cc (ctrl_c_handler): Avoid special pgid checking if no tty is
associated with the process.
(Suggested by Tim Baker <dbaker@direct.ca>)
* external.cc (fillout_pinfo): Return actual tty number for ctty.
* fhandler_console.cc (get_tty_stuff): Set ctty when shared memory is
allocated.  Accept flags input from open().
(set_console_ctty): New function.
(fhandler_console::open): Pass flags to get_tty_stuff and rely on this function
to set the ctty, if appropriate.
* fhandler_termios.cc (fhandler_termios::set_ctty): Move to tty_min class.
* fhandler_tty.cc (fhandler_tty_slave::open): Use tc field to access
set_ctty().
* tty.h (TTY_CONSOLE): Move to include/sys/cygwin.h.
(tty_min): Add set_ctty class here.
* include/sys/cygwin.h (TTY_CONSOLE): New home here.
* path.cc (symlink_info): Make contents an actual buffer.  Pass more flags to
case_check.
(path_conv::check): Reorganize to do parsing based on posix path rather than
native path.
(symlink_info::check): Expect posix path as input.  Translate to native path
here.  Accept path_conv flags.  Stop parsing if not a symlink regardless of
whether previous path was a symlink.
