Rebase our patchset on the upstream 2017.8 release. No major changes to the packaging apart from the libgpgme11-dev dependency change noted above and the --enable-experimental-api flag.

This should eventually be pushed with the Version_2017.8_debian tag.

The code side of this is PR #76.

I have a horrible feeling that the build has succeeded with me updating libostree-1-1.symbols though. That needs further attention.

[pwithnall]

Updated to include the fixes from PR #75 and update the symbols file.

@pwithnall It's not clear to me whether these PRs are still valid or if we're targeting a later release now for the full rebase work. Let me know if this still needs review.

This is obsolete now, as upstream OSTree has made a release (2017.9) which includes all these patches. But then we’ve also made some more local fixes which we’d need to base on top of that. Probably best to abandon this PR, for me to carry on making local fixes while adding flatpak unit tests (upstream flatpak/flatpak#884), and then we re-do this PR once we’ve got a stable stack of OSTree fixes. Most of them will probably end up being in the OSTree 2017.10 release.
