* autoload.cc (LoadFuncEx): Define via new LoadFuncEx2 macro. (LoadFuncEx2): Adapted from LoadFuncEx. Provides control of return value for nonexistent function. (NtQueryObject): Declare. (IsDebuggerPresent): Declare via LoadFuncEx2 and always return true if not available. * debug.h (being_debugged): Just rely on IsDebuggerPresent return value. * dtable.cc (handle_to_fn): New function. (dtable::init_std_file_from_handle): Attempt to derive std handle's name via handle_to_fn. (dtable::build_fhandler_from_name): Fill in what we can in path_conv structure when given a handle and path doesn't exist. * fhandler.cc (fhandler_base::open): Don't set the file pointer here. Use pc->exists () to determine if file exists rather than calling GetFileAttributes again. * fhandler.h (fhandler_base::exec_state_isknown): New method. (fhandler_base::fstat_helper): Add extra arguments to declaration. (fhandler_base::fstat_by_handle): Declare new method. (fhandler_base::fstat_by_name): Declare new method. * fhandler_disk_file (num_entries): Make __stdcall. (fhandler_base::fstat_by_handle): Define new method. (fhandler_base::fstat_by_name): Define new method. (fhandler_base:fstat): Call fstat_by_{handle,name} as appropriate. (fhandler_disk_file::fstat_helper): Accept extra arguments for filling out stat structure. Move handle or name specific stuff to new methods above. (fhandler_disk_file::open): Use real_path->exists rather than calling GetFileAttributes again. * ntdll.h (FILE_NAME_INFORMATION): Define new structure. (OBJECT_INFORMATION_CLASS): Partially define new enum. (OBJECT_NAME_INFORMATION): Define new structure. (NtQueryInformationFile): New declaration. (NtQueryObject): New declaration. * path.cc (path_conv::fillin): Define new method. * path.h (path_conv::fillin): Declare new method. (path_conv::drive_thpe): Rename from 'get_drive_type'. (path_conv::volser): Declare new method. (path_conv::volname): Declare new method. (path_conv::root_dir): Declare new method. * syscalls.cc (fstat64): Send real path_conv to fstat as second argument.
