Brian Behlendorf a91258913f Prepare SPL repo to merge with ZFS repo
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.
