Fix bug #18528 with crashes at startup during frameset restoration.
src/w32term.c (w32_read_socket): Don't use frame dimensions for resizing if GetClientRect returned an empty (0, 0, 0, 0) rectangle. Check the return value of GetClientRect, and don't use the results if it didn't succeed. src/dispnew.c (change_frame_size_1): Recompute the frame dimensions in columns and lines after correcting the pixel dimensions in check_frame_size. (adjust_decode_mode_spec_buffer): Add assertion to avoid passing negative values to xrealloc.
