[PySide] Pyside repos merge

[Alexandru Croitor]

Hi all,

The merging of the pyside-setup, shiboken and pyside2 repos is imminent.
The old repos will stay around for some time, and eventually get deleted, and the repository that should be used from now on is pyside-setup.

The examples, tools, and wiki submodules will remain as usual.

The good side of things is that shiboken / pyside / pyside-setup changes can happen in single atomic commits. 
All git history is saved.
And management of the CI side of things should be much simpler now.

There are a few downsides:
- there are going to be a couple bogus merge commits for the actual repo merging, which will have a non-buildable state.

- git bisect will not work properly for commits before the repo merge, because checking out a previous revision of a submodule will only contain the sources of that submodule, and not of the whole super tree. If you want to do a build of previous commits, you will have to jump through some hoops, mainly manually replicating the 3 previous submodule file structures, either by git cloning 3 times, or setting up self-referential submodules with different SHA1s.

- builds of previous commits won't work unless you do the steps outlined above.

- all existing un-merged gerrit changes will have to be rebased. The best way I see for this is using git-format-patch, modifying the files paths in the generated patches, and applying them in the new repo.

- maybe something else which I'm currently not seeing.

Regards,
Alex.
