In FreeBSD, there are three compile environments that are supported:
user land, the kernel and the bootloader / standalone. Adjust the
headers to compile in the standalone environment. Limit kernel-only
items from view when _STANDALONE is defined.

When debugging issues or generally analyzing the runtime of
a system it would be nice to be able to tell the different
ZTHRs running by name rather than having to analyze their
stack.

The progress of a send is supposed to be reported by `zfs send -v`, but
it is not. This works by creating a new user thread (with
pthread_create()) which does ZFS_IOC_SEND_PROGRESS ioctls to check how
much progress has been made. This IOCTL finds the specified send (since
there may be multiple concurrent sends in the system). The IOCTL also
checks that the specified send was started by the current process.
On Linux, different threads of the same process are represented as
different `struct task_struct`s (and, confusingly, have different
PID's). To check if if two threads are in the same process, we need to
check if they have the same `struct task_struct:group_leader`.
We used to to this correctly, but it was inadvertently changed by
30af21b025 (Redacted Send) to simply check if the current
`struct task_struct` is the one that started the send.
This commit changes the code back to checking if the send was started by
a `struct task_struct` with the same `group_leader` as the calling
thread.

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.
