Drop Netbinox and unused eclipse modules

Netbinox is a patched version of Equinox (the Eclipse OSGI runtime
conainer). The patch is bases on a Equinox version from 2014. The patch
was evolved to allow "Import-Package" declaration for JDK packages if
they are declared optional. This works as long as the imports are
declared optional. This is not the case for a growing number of
libraries.

NetBeans already carries an up-to-date OSGI container (Apache Felix), so
use that and drop the custom dependency.

In the wake of this the following modules were removed too:

  - o.eclipse.core.contenttype
  - o.eclipse.core.jobs
  - o.eclipse.core.net
  - o.eclipse.core.runtime
  - o.eclipse.core.runtime.compatibility.auth
  - o.eclipse.equinox.app
  - o.eclipse.equinox.common
  - o.eclipse.equinox.preferences
  - o.eclipse.equinox.registry
  - o.eclipse.equinox.security

It is assumed that equinox was added to be able to run eclise modules,
which in turn were required for Mylin (Bugtracking integration). The
latter was dropped, so the dependencies should be removed to reduce the
dependency footprint.
