term: need windows support

[davecheney]

16b2e60 make term/termios a noop under windows, but the higher level term package is still POSIX specific.

The plan is to add a new low level package for windows, term/win32 (just an example, please don't flame) and adjust the term package to use it depending on the host GOOS.

As to the noop, this package doesn't build on (my) Windows:

$ go get github.com/pkg/term
# github.com/pkg/term/termios
C:\Users\bep\go\src\github.com\pkg\term\termios\pty.go:25: undefined: ptsname
C:\Users\bep\go\src\github.com\pkg\term\termios\pty.go:30: undefined: grantpt
C:\Users\bep\go\src\github.com\pkg\term\termios\pty.go:35: undefined: unlockpt
