[Releasing] [Development] HEADS-UP: Qt 5.6 feature freeze and branching coming

[Oswald Buddenhagen]

5.6 branching is now complete (*).
anything that integrates to dev now is 5.7 material - as usual, no
cherry-picks.

(*) well, actually, it's, not, because the qtbase downmerge is
non-trivial and needs a review and an integration run, but that's
relevant only for RM, not for the developers.

a mini-post-mortem already: as every single time so far, something went
wrong with the supermodule (this time it was bad versioning in canvas3d,
which repeatedly threw off the branch/merge script). for a smooth
process, it's really essential that the supermodule and all submodules
are in a consistent state *before* the branching *starts*.
take that as a reminder that if you are adding a new module to the
supermodule, it's your responsibility to verify that the module is
actually built in a sane way within the new context.

We will use soft branching like earlier so there should be enough time to finalize ongoing changes for Qt 5.6 in 'dev' & start using '5.6' branch for Qt 5.6 development. And like earlier final downmerge from 'dev' to '5.6' will happen ~ after a week (Most probably Monday 17th Aug).
