[SRU] 2.12

[Michael Vogt]

This is a new version of snapd.

The changelog for 2.12 is available here https://github.com/snapcore/snapd/blob/2.12/debian/changelog, the raw git changelog is available here: https://github.com/snapcore/snapd/commits/2.12 (note that the debian changelog is auto-generated from the merges of the git commits so there is usually no need to look at the raw git commits).

The snappy team released a new 2.12 micro release that we want SRU into xenial. The new process described in https://wiki.ubuntu.com/SnapdUpdates was used and we have done integration-tests on the snappy images, autopkgtests on classic and unit tests.

The following automatic tests are run:
- travis unit tests https://travis-ci.org/snapcore/snapd/branches (check for 2.12 here)
- travis/spread based integration/system tests: https://travis-ci.org/snapcore/snapd/branches (check for 2.12 here under "spread")
- jenkins autopkgtests http://162.213.35.179:8080/job/snappy-by-tag-autopkgtest/16/
- jenkins integration tests: http://162.213.35.179:8080/job/snappy-by-tag-integration-test/17/

The following additional tests were performed:
"""
- adt-buildvm-ubuntu-cloud
- customize the resulting image: "sudo apt install snapd && sudo snap install hello-world && hello-world.env && sudo snap remove hello-world" (ensures the base image has the old debs and the daemon has some state)
- adt-run --source snapd_2.12.dsc --- adt-virt-qemu adt-xenial-amd64-cloud.img: PASS
"""
This included the upgrade from 2.0.11 as part of the autopkgtest run. There are also various snaps installed/removed (including installing and running ubuntu-calculator-app in xvfb) and run as part of the auto pkg test, including reboots to ensure that the system keeps working over reboots.

After installing the new snapd it was ensured that apt is unaffected by doing:
"""
- sudo apt install -y hello && sudo apt remove -y hello
"""

After installing the new snapd gnome-software was used:
"""
- install "http" (snap) and remove it again
"""
All worked as expected.

@mvo -- this upload reinstates the postrm purge support that was a problem in 2.11. I was expecting it to either stay unchanged, or move to the new more intelligent purge.

Hello Michael, or anyone else affected,

Accepted snapd into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/snapd/2.12+0.16.04 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
