behlendo f1ca4da6f7 Initial commit. All spl source written up to this point wrapped
in an initial reasonable autoconf style build system.  This does
not yet build but the configure system does appear to work properly
and integrate with the kernel.  Hopefully the next commit gets
us back to a buildable version we can run the test suite against.
