    …tly consisted switching from per-class instances of Random() that are shared amongst threads to thread-local instances shared across classes.
    
    Also, CounterGenerator.nextInt() was synchronized.  Changed it to use an AtomicInteger.
    
    Finally, removed lastString() from Generator, as it was only called in places where lastInt() was more appropriate; switched the calls to lastInt().

    …on-colliding keys. Unforunately, for reasonably sized
    
    workloads, this leads to key collisions, which throws off experiments.
    
    The implementations of the FNV32 and FNV64 hash functions we use manipulate signed integers instead of unsigned integers, so it
    is unclear if this is a limitation of the FNV algorithms or of our implementations.
    
    As a workaround, this patch switches from FNV32 to FNV64, reducing the chances of such bad behavior (and eliminating it in our
    experiments to date).

  1. Make it easier to build the database client libraries:

    Russell Sears authored
     1) Add Makefile.download-db-libs, which downloads + unpacks all of the dependencies.
     2) Fix build.xml so that downloaded libraries don't break ant doc
     3) Add dbcompile-all target that builds all of the client libraries at once.
  2. change DB API to use ByteIterator for fields instead of String. This …
