fast-serialization

• removed variants using Unsafe ("fst.unsafe" is ignored). Major degradation for large primitive arrays only.
• setPreferSpeed option is ignored (little effect on runtime, much larger output)

these options might come in with a new release+design change again (needed refactoring to reduce redundant code)

• init-time of stream improved (good when writing smallish objects)
• performance optimizations (classname encoding, unshared r/w)
• structs retested+fixed some issues. added struct testcases to default test run
• separated test in another repository (except struct tests)

• 1.41 actually deoptimized, cache locality > everything

• minor performance improvements
• minor reduction in output size.

• "fix" in 1.39 was wrong (was an issue in the testing program). 1.39 passed all tests but had issues in a large real world app. 1.40 corrects that.
• modified testcases because someone suspected they are skewed (moved initialization to constructor from instance initializer). Turns out it did not make a difference.

• fix: IndexOutOfBoundsException with very short BYOStreams

• minor performance optimizations
• improved performance running in "unshared" mode (no check for double objects, cycles in graph). Since this allows cutting some corners and checks, new ..NoShared subclasses of FSTObjectIn/Output were added. Note you can't use mixed flavours sharing a single FSTConfiguration (create a separate FSTConfiguration for "no shared ref" and "default mode" within a single app).
• did some cleanup on exception handling

Many bugfixes in serialization

• fixed issue with serialize/deserialize inbetween 32bit and 64bit VM's
• unsafe turned off by default (use -Dfst.unsafe=true to enable, be careful. Only use with well tested software !)
• fix: order of serialization could mess up when encoding legacy style serialized objects
• fix: classes which only contain boolean fields caused errors
• fix: void.class is also a primitive class
• Issue 23 sample app runs (hardcore spring webflow serialization with tons of corner cases)

I start moving over FST to github
