I still need to deal with the autofs module.

I'm reluctant to remove it and do the rename at the same time the other
changes are going in.

I thought a better idea would be to leave the autofs module in place for
the moment and change the Kconfig help message to describe what is going
to happen and alert users to the fact it won't work and also change all
the defconfig files that select autofs to select autofs4.

Thoughts please?
