[Bug 1333728] Re: update-manager should support HWE EOL transition

There is an issue when I test with update-manager 1:0.156.14.15 (sorry I
didn't find the ubuntu bug for update-manager, so I add my comments
here).

1. install ubuntu 12.04 on an amd64 machine
2. install the hwe lts-saucy stack
3. enable i386 support
4. install libgl1-mesa-glx-lts-saucy:i386
5. use update-manager to upgrade to the lts-trusty stack

Step 5 will fail with an error:

The following packages have unmet dependencies:

```
libgl1-mesa-glx-lts-trusty: Depends: libglapi-mesa-lts-trusty (= 10.1.3-0ubuntu0.1~precise1) but 10.1.3-0ubuntu0.1~precise1 is to be installed
                            Depends: libx11-6 (>= 2:1.4.99.1) but 2:1.4.99.1-0ubuntu2.2 is to be installed
                            Depends: libxdamage1 (>= 1:1.1) but 1:1.1.3-2build1 is to be installed
xserver-xorg-lts-trusty: Depends: xserver-xorg-core-lts-trusty (>= 2:1.11) but 2:1.15.1-0ubuntu2~precise1 is to be installed
```

The output of hwe-support-status --show-replacements is:
linux-generic-lts-trusty linux-image-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty

However since there is libgl1-mesa-glx-lts-saucy:i386 installed we
should also put libgl1-mesa-glx-lts-trusty:i386 into the replacements
list.

In fact for each package in the replacements list we should check if
it's also installed for other multiarch and add the lts-trusty
replacement to the list too.

Title:
  update-manager should support HWE EOL transition

Status in “update-manager” package in Ubuntu:
  Invalid
Status in “update-notifier” package in Ubuntu:
  Invalid
Status in “update-manager” source package in Precise:

Status in “update-notifier” source package in Precise:

Bug description:
  In ubuntu 12.04 parts of the older HardwareEnablementStack is going
  out of support soon. update-manager should support the transition to
  the new HardwareEnablementStack (HWE).

  Impact:
  - all user with of ubuntu 12.04.{2,3,4} are affected and need the update to have a good transition

  Testing:
  - install 12.04.2 (or .3, .4)
  - run update-manager
  - verify that nothing special happens (except for updates being available :)
  - install update-manager from precise-proposed
  - start update-manager and verify that a "new hardware support" label becomes available with a install button
  - log into a console and verify that you get a message after login that you need to upgrade your hardware support
  - run ubuntu-support-status and verify that it displays information about the new HWE support
  - click the button, verify that information is available and click install
  - after the install is finished, reboot and verify that update-manager does not display anything about the hardware again
  - verify that ubuntu-support-status and /etc/motd do not contain references to the HWE anymore

  Potential risk:
  - if the new update-manager is buggy this may prevent users from getting updates, so we need to test this carefully
