This patchset is *almost* the same as the previous patchset, but it got
fragmented in multiple patches for easier review.
I am not setting any version on these patches as they do not match
previous versions.
The idea behind splitting patches is that they should be mergeable and
compilable one-by-one.
Ideally they should not introduce any regression in existing
functionalities, however, it may not always be apossible to *test* the
new code as it will require a subsequent patch to be used. Still we will
be able to compile the new code and review it.
While splitting patches, some ugly things have been fixed/changed..so
hopefully splitting patches has already paid off a bit..
I hope this will help with getting this new functionality merged soon.
This patchset reflects what is currently pushed to the "dco" branch.
