Leverage OSGi-DS component-xml file generation of PDE-DS/Tycho

[HannesWell]

Remove all generated xml-files from git.

Especially the component-xml files are annoying since the state in git is not up to date. Consequently they are changed on each build and make the git staging dirty.

The EventAdmin is currently not generated xml maybe better place that in a separate PR?

Yes, see #662.

Although the test failure was in equinox.ds.tests.

[HannesWell]

I really don't understand why the test is failing.
I could reproduce it locally when the component XML files are missing, but the logs say they are generated before the tests are executed?

Suggested change

	OSGI-INF/org.eclipse.equinox.*.xml
	OSGI-INF/*.xml

[HannesWell]

I reduced it now to OSGI-INF/org.eclipse.*.xml, but ignoring all XML could be too restrictive. And since in the fast majority of cases the classes in eclipse projects are in a org.eclipse... package this should be fine. And if not, one will notice it quickly and can adjust the pattern in that specific case.

I assume the problem is that the bundle is not packed before executed as a test and then the launcher looks for ${basedir}/OSGI-INF (that is empty) but the files are generated at ${basedir}/target/classes/OSGI-INF

Yes. :/
I now remembered the work-around I implemented in eclipse-platform until this works out of the box:
