ref-manual, dev-manual: Applied review edits (read-only rootfs and package repo)

A couple sets of review comments from Paul applied here.

1. Added the "read-only-rootfs" item to the EXTRA_IMAGE_FEATURES
   variable description and a link to the appropriate section
   in the dev-manual.

2. Pulled the how-to-create a package repository section out
   of the section on how to customize an image with the
   IMAGE_FEATURES and EXTRA_IMAGE_FEATURES section and made
   it a stand-alone section in the "Tasks" chapter of the
   dev-manual.

3. Integrated the SSH server example into the main topic
   because we don't want an isolated sub-section within a
   main topic.

4. In the image features section of the ref-manual, I fixed
   the link with the "read-only-rootfs" feature to go to
   the now-isolated section on how to do that instead of
   going to the customizing an image using the IMAGE_FEATURES
   and EXTRA_IMAGE_FEATURES variables section.
