Since at this point we are not considering moving either all POSIX
related modules or all application-level modules to a new naming
convention, I think it's best to rename the application-level module 'pipe'
at this point.

In a second step, in a couple of months, we'll be able to remove the
module 'pipe' without much damage.

In a third step, later again, you can then rename 'pipe-posix' to 'pipe'.
