classes: Fix alternatives and rc.d ordering
When using an alternative as an initscript, the ordering between
update-rc.d and update-alternatives tasks during prerm and postinst
tasks must always be the following in order to work:
* prerm:
- stop daemon
- remove alternative
* postinst:
- add alternative
- start daemon
This patchset adds comments to the scripts generated by both classes and
organize the generated sections based on those comments.
