Code movement only. If someone finds function 'foo' in "foo_linux.go", they will expect that the Window version of 'foo' exists in "foo_windows.go". Current code doesn't follow this manner. For example, 'sameFile' exists in "file_unix.go", "stat_plan9.go" and "types_windows.go". The CL address that problem by following rules: * readdir family => dir.go, dir_$GOOS.go * stat family => stat.go, stat_$GOOS.go * path-functions => path_$GOOS.go * sameFile => types.go, types_$GOOS.go * process-functions => exec.go, exec_$GOOS.go * hostname => sys.go, sys_$GOOS.go Change-Id: Ic3c64663ce0b2a364d7a414351cd3c772e70187b Reviewed-on: https://go-review.googlesource.com/27035 Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>
