Upgrading to SigTest 1.4 and using its release attribute

[jtulach]

New version of SigTest supports the release attribute. That allows us to fix the JDK API to particular version. The PR sets it to ${javac.target} for each module. To verify how this behaves try for example:

platform/openide.util.lookup$ ant clean build check-sigtest -Djavac.target=11  -Dsigtest.check.type=strictcheck

e.g. the report includes changes done in between JDK8 and JDK11 to Object.finalize and attributes of Deprecated. CCing @neilcsmith-net + @geertjanw

[jtulach]

First error is reported and it can be interpreted as the power of --release option!

Class org.netbeans.lib.profiler.utils.ImmutableList
  "E1.2 - API type removed" : method public java.util.Spliterator java.lang.Iterable.spliterator()
  "E1.2 - API type removed" : method public void java.lang.Iterable.forEach(java.util.function.Consumer)

The lib.profiler project sets javac.target=1.7 and SigTest version 1.4 properly sees only JDK7 APIs now!

[neilcsmith-net]

Looks a good move! I was just going to liaise with @geertjanw about the API snapshot, which for 12.3 we did initially before freeze so we could get useful review. Is this intended for 12.4? Should we wait until this merges?

[JaroslavTulach]

Yes, if it seems to work (and it does). Let's use it for 12.4.
