Update to the upstream 1.12.1 bugfix version

[Sebastien Bacher]

* Impact

The update fixes memory handling issues which could potential have security implication. It was requested by the MIR team on https://bugs.launchpad.net/ubuntu/+source/wpebackend-fdo/+bug/1973033/comments/11 as we need to promote the package for incoming webkitgtk security updates

Fedora issues an update on similar concern https://bodhi.fedoraproject.org/updates/FEDORA-2022-f98ab9f311

* Testcase

Unfortunately it's not easy to test wpebackend-fdo since the project has no tests nor demo utility. The backend is used mostly by webkitgtk but the current archive version is built without that option. It is a requirement for newer webkitgtk series though and such for incoming security update (since newer webkitgtk series are rolled out as security updates)

* Regression potential

The changes are small fixes for memory management issues but if those were wrong then it could lead to rendering issues or crashes in webkitgtk clients once webkitgtk is build with libwpe.

The current version in Kinetic and Lunar are newer

It looks like (for Jammy, at least) there is an in-archive consumer of libwpebackend-fdo-1.0-1 - cog. We need at least a minimal smoke test for SRU verification, and that should suffice. I don't have a Jammy system handy, and cog isn't in the archives post-Jammy - could someone please cook up a minimal test case using cog?

[Sebastien Bacher (seb128)]

@Chris, I've tried that bug 'cog' seems to just not be working, bug #1970779 has some details

$ cog http://www.ubuntu.com

(cog:8292): Cog-WARNING **: 09:19:22.193: Cannot create platform: Could not find an usable platform module
wpe: could not load the impl library. Is there any backend installed?: libWPEBackend-default.so: cannot open shared object file: No such file or directory
Abandon (core dumped)

Trying to force the platform or under X or Weston doesn't change the behavour

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

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

I've rebuilt webkitgtk the wpe support enabled in a ppa, built using proposed and the package from this SRU

testing epiphany-browser with wpebackend-fdo 1.12.1-0ubuntu1 browsing some websites works as expected, including playing videos on youtube. I'm marking it as verified
