A first version, some tests may use old API, which therefore not compile.

This is a very tricky pert, because you can do lots of errors. Things from 2.9 which were not 100% correct:

• CompoundFileReader.list() was there (deprec), but no listAll(). Renamed function. Does listAll/list difference has any effect in CFR?
• There was one class to list() in SegmentInfos, replaced by listAll()

This patch also makes FSDir abstract and removes all deprecated methods and also the hell of reflection and the system properties.

Patch still needs fine-tuning and test adaption.

Does listAll/list difference has any effect in CFR?

This should be fine; we don't normally put non-index files into a CFS.

Updated patch, works with current trunk and backwards branch (after tag was added, not yet done). The previous poatch had some errors because of init() methods and previous closeDir parameter (wrong method was called in some cases)

Contrib tests not yet functional, but test-core works.

Here are the fixes for contrib to not use the deprecated IndexReader/IndexWriter/FSDir/IndexSearcher methods/ctors.

Now this issue is ready for the final commit.

It would be good, if somebody other would again look over the original patch.

I think, I have to commit this now. The current tests in trunk do not compile, as there is now a problem with abstract methods in the MockFSDirectory and FaultyFSDirectory (I was too fast in modifying them and tested only with my changes from this patch).
