Fix 436653: conditional aspect activation plus various polish
Modified test expectation system so it is possible to say
the test cares about one particular message and the rest
do not matter (prefix message string with '*') - crude but
quick.
Polished many places to exploit generics
Upgraded all the tests to work on Java8 - some serious changes
regarding ajdoc on Java8. Hopefully it has stayed backwards
compatible with earlier JDK versions (e.g. if using AspectJ 1.8.3+
with a JDK less than 8) but no explicit testing done for this.
fixes inefficient ordering of tests in SignaturePattern (that I inadvertantly introduced earlier), and corrects @DeclareParents impl in AJTypeSystem :- fields should NOT be shown, and nor should non-interface members.
Some updates for 118754. The various places that were checking for 'MISSING' now call 'isMissing' if they can. I think this negates some work Adrian did with introducing MissingWithKnownSignature - but we have to make this change for LTW to work properly. Someone with a bit of time on their hands should go through all the places isMissing() is now called and see if the check should be 'isReallyMissing()' which would allow the MissingWithKnownSignature to get through. I will raise an enhancement to cover this.
