Add the FreeBSD platform code to the OpenZFS repository. As of this commit the source can be compiled and tested on FreeBSD 11 and 12. Subsequent commits are now required to compile on FreeBSD and Linux. Additionally, they must pass the ZFS Test Suite on FreeBSD which is being run by the CI. As of this commit 1230 tests pass on FreeBSD and there are no unexpected failures.
