This commit removes everything from the repository except the core SPL implementation for Linux. Those files which remain have been moved to non-conflicting locations to facilitate the merge. The README.md and associated files have been updated accordingly. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
