[jdt-core-dev] Stabilization for next integration build

["Philippe P Mulet" <philippe_mulet@xxxxxxxxxx>]

We have quite a big number of changes going in, and we need to reach some
stability for the next integration build.
In particular, in the API area, if we deprecate anything, the replacement
should be available immediately. If not, we will drag the attention of
clients, and look stupid.
In most cases, it feels to me that deprecation flag should be added once we
think we are done (not sooner).

Of course, we must be backward compatible until clients have migrated
(within 3.0).
