Return unique inode numbers when calling stat/fstat on pipes and IP sockets
* fhandler.h (class fhandler_base): Convert unique_id to int64_t. (fhandler_base::set_ino): New protected inline method. (fhandler_base::get_unique_id): Convert to int64_t. (fhandler_base::set_unique_id): New inline method taking int64_t. (fhandler_pipe::fstat): Declare. (fhandler_pipe::init): Take extra parameter. (fhandler_pipe::create): Ditto. * fhandler_socket.cc (fhandler_socket::init_events): Set inode number to serial number. (fhandler_socket::fstat): Set device to DEV_TCP_MAJOR. Create st_ino from get_ino. * include/cygwin/signal.h (struct _sigcommune): Replace _si_pipe_fhandler with _si_pipe_unique_id. * pinfo.h (_pinfo::pipe_fhandler): Take unique id instead of HANDLE. * pinfo.cc (commune_process): Accommodate change to _si_pipe_unique_id. (_pinfo::commune_request): Ditto. (_pinfo::pipe_fhandler): Ditto. * pipe.cc (fhandler_pipe::init): Take unique id as argument and set inode number and unique_id from there. (fhandler_pipe::open): Rework to find any matching pipe from unique id in filename. (fhandler_pipe::get_proc_fd_name): Create filename using inode number. (fhandler_pipe::create): Generate and return unique id from process pid and pipe_unique_id. In outer method, call init with additional unique id as parameter. (fhandler_pipe::fstat): New method. (pipe_worker): Accommodate using 64 bit inode number in filename. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
