Demoting "init" to Priority: important

[Ansgar Burchardt]

Hi,

as written earlier[1] I would like to demote the "init" package from
Priority: required & Essential: yes to Priority: important.

This needs at least a change to the provider of update-rc.d/invoke-rc.d:
these two programs are called in maintainer scripts and should probably
be provided by an essential package[2]. This means moving the Essential:
yes bit from "init" to "sysv-rc"; as sysv-rc is already pseudo-essential
this should be no real issue.

Do we need any other changes in order to demote "init"?

  [2] I'm not opposed to changing that, but doing so probably requires
      changing all packages providing init scripts.
