Sync qtwebkit-opensource-src from Debian (enable webp)

[Jeremy Bícha]

The last merge from Debian has this changelog entry:

  * Sync with Debian packaging, remaining changes:
    - Build without WebP (in universe)
    - Own .symbols file

https://launchpad.net/ubuntu/+source/qtwebkit-opensource-src/5.6.1+dfsg-4ubuntu1~2

But libwebp is in main and has been for a while. The only part that's in universe is the webp binary package which is not a dependency of anything (and honestly I don't know why it's not in main too, it's not mentioned on the MIR LP: #1186553 )

https://people.canonical.com/~ubuntu-archive/madison.cgi?package=libwebp&S=on

That leaves the only change as using an Ubuntu-specific symbols file. I don't know how Qt symbols work but maybe that's not needed anymore.

Copied to https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2324, to see if it builds successully on all our architectures.

The symbols files are mostly identical, so they should not be a problem.

One thing that bothers me is that after I copy 5.6.1+dfsg-5 to Zesty, the auto-syncer will sync the latest Debian upload (5.7.1~20161021+dfsg-2) which will dep-wait, so there is a risk that my sync won't be able to migrate.

Do you have any ideas how to deal with that?

[Jeremy Bícha (jbicha)]

The easiest way to stop something from autosyncing is to use an ubuntu# version number! :)

We could just wait for the Qt 5.7 transition (in January I think): bug 1640290

[Launchpad Janitor (janitor)]

This bug was fixed in the package qtwebkit-opensource-src - 5.6.1+dfsg-5ubuntu1

---------------
qtwebkit-opensource-src (5.6.1+dfsg-5ubuntu1) zesty; urgency=medium

  * Re-sync with Debian unstable, no changes remaining.
  * Re-enable WebP, it is in main since Trusty (LP: #1652166).
  * Drop debian/patches/fix_pthread_linking.diff, it was applied upstream
    in 5.6.1 and wrongly rebased in 5.6.1+dfsg-1 upload.
  * Fix a Lintian warning about space in license name.
