Implement terminal handling, input polling, and vdprintf() for Windows. Because Windows I/O model differs fundamentally from Unix and there is no concept of character device, polling is simulated depending on the underlying input device. Supporting non-terminal input is useful for automated testing. Windows emulation of VT100 uses "ESC [ E" for newline instead of standard "ESC E", so add a workaround.
