* dtable.cc: Define various device-related string constants as wide character

constants.
(dtable::init_std_file_from_handle): Reorganize pipe handling to try to catch
special tty case.
(build_fh_name_worker): Declare for common use.
(build_fh_name): Define char version.
(build_fh_name): Define (currently unused) UNICODE_STRING version.
(decode_tty): Detect if pipe is actually a cygwin tty, returning the tty name
in the buffer.
(handle_to_fn): Reorganize to use wide characters.
* dtable.h (build_fh_name): Declare (currently unused) UNICODE_STRING version.
* fhandler_tty.cc (fhandler_pty_master::setup): Use
fhandler_pipe::create_selectable to create a pipe with a given name.
* pipe.cc (pipe_handler): Make returned handle inheritable.
(fhandler_pipe::create_selectable): Take an optional name.  Use a standard
cygwin introducer for the name.
* path.cc (path_conv::check): Make first argument const.
* path.h (path_conv::check): Ditto for declaration.
(path_conv::path_conv): Ditto for UNICODE_STRING version.
