Christopher Faylor 2e008fb91f Change use of BOOL, TRUE, FALSE to bool, true, false, as appropriate,
throughout.
* tty.cc (tty::common_init): Remove call to SetKernelObjectSecurity and edit
some comments.
* cygheap.h (init_cygheap::ctty): Add new element.
* devices.in (device::parse): Remove special handling for /dev/tty.
* devices.cc: Regenerate.
* dtable.cc (build_fh_pc): Don't reset /dev/tty device.  Let the device opener
do that.
* fhandler_termios.cc (tty_min::set_ctty): Redefine to _pinfo class.
* fhandler_tty.cc (fhandler_tty_common::set_close_on_exec): Avoid setting
noninherit flag for ctty.
* tty.h: Move BOOLs to bools.
(tty_min::set_ctty): Redeclare to _pinfo class.
* pinfo.cc (_pinfo::set_ctty): Define new function based on tty_min::set_ctty.
Change first argument from tty number to tty_min class.
* pinfo.h (_pinfo::set_ctty): Declare.
* fhandler_console.cc (fhandler_console::get_tty_stuff): Reflect move of
set_ctty to _pinfo class.
* fhandler_tty.cc (fhandler_tty_slave::open): Treat FH_TTY specially.  Use
saved cygheap value if it exists.  Otherwise convert to real device and save on
first time open.
(fhandler_tty_common::dup): Potentially set controlling tty if duping a slave
tty.
* syscalls.cc (setsid): Close controlling tty in cygheap.
* tty.cc: Change some BOOLs to bools.
