[e4-dev] Split up org.eclipse.e4.core.di

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

Hi,

Currently the annotation one uses to e.g. mark something optional
(@Optional), executable (@Execute), ... is defined in core.di and so one
inherits directly a dependency on the whole di-container which is
contra-dictionary.

I propose we split out the annotations-package in an extra bundle and
make the original bundle require and reexport it.
