operators to simplify testing for directory and attributes, throughout. * path.h (path_conv::exists): New method. (path_conv::has_attribute): Ditto. (path_conv::isdir): Ditto. (path_conv::DWORD &): New operator. (path_conv::int &): Ditto. * dir.cc (rmdir): Eliminate a goto. * dtable.cc (dtable::build_fhandler): Accept opt and suffix info for path_conv.check. Return fh == NULL on path_conv error. Pass unit to set_name as appropriate. (dtable::reset_unix_path_name): New method. * dtable.h (dtable): Declare new method. Reflect arg changes to build_fhandler. * fhandler.cc (fhandler_disk_dummy_name): Eliminate. (fhandler_base::set_name): Expect paths to be NULL. Build unix_path_name from win32_path_name when it is a device. (fhandler_base::reset_unix_path_name): New method. (fhandler_base::raw_read): Report EISDIR when ERROR_INVALID_FUNCTION or ERROR_INVALID_PARAMETER and reading a directory. (fhandler_disk_file::fstat): Don't call stat_dev since we should now never be calling fhandler_disk_file methods with devices. (fhandler_base::fhandler_base): Clear {unix,win32}_path_name. (fhandler_base::~fhandler_base): Always free {unix,win32}_path_name. (fhandler_disk_file::fhandler_disk_file): Remove set_no_free_names kludge. (fhandler_disk_file::open): Ditto. * fhandler.h (fhandler_base::no_free_names): Eliminate. (fhandler_base::set_no_free_names): Ditto. * fhandler_tty.cc (fhandler_tty_slave::fhandler_tty_slave): Don't set unix_path_name here. * path.cc (fchdir): Lock fd table throughout. Use new dtable::reset_unix_path_name method to reset path. * syscalls.cc (stat_worker): Reorganize to always call fstat method. Pass path_conv method to fhandler_*::open. (chroot): Elminate a goto.
