There are some pieces in here I like but I'm not sure overall this is
the right way to make this work. For example, lets say I want to use the
eclipse tools with a plain sato image. Its hard for me to do this with
the patches as they stand. We need to take a step back and think how a
user is going to expect this to work.

I think what we need to do at the basic level is have something like an
IMAGE_FEATURE that we can turn on that pulls in the various IDE
integration pieces. In this case, it would explicitly add openssh/sftp
and we should use the package manager functionality to replace dropbear
with openssh when an image requests both.

This IMAGE_FEATURE would then be on by default for the -sdk image but
could easily be enabled for others.

Cheers,
