This pollutes the build log and is not needed.

ctf.core: Remove dependency to o.e.tc.common.core

By removing this dependency this plug-in will be independent to other
Eclipse plug-ins and can be deployed as maven artifact with less
third-party dependencies.

Note, that class SaturatedArithmetic is copied from plug-in
org.eclipse.tracecompass.common.core. The original tests are refactored
and a test suite was added in ctf.core.tests added so that the new class
is tested, too.
