win32: add support for virtual terminal input

Alter certain applets to support virtual terminal input, if enabled.

In many places this is achieved by building previously excluded
upstream terminal-handling code.  The busybox-w32 implementation
of termios(3) functions does nothing if virtual terminal input is
disabled, so it can be invoked regardless.

Some applet-specific terminal-handling code is also required.

This affects less, more, vi and command line editing in the shell.
(The `more` applet isn't enabled in the default configuration.)

This series of patches adds about 1.7KB to the binaries.
