Brian Behlendorf 9a3d5378c6 Clean up emulation of kernel threads in userspace.
Updated to use pthread thread specific data rather than keeping
a global list.  This also fixes at least one easily reproducible
crash in ztest

Brian Behlendorf 7069d048a0 Revert kthreads based on pthread thread specific data due to failure.
With this patch applied I get the following failure 100% of the time,
I'd prefer to debug it and keep moving forward but I do not have the
time right now so I'm reverting the patch to the version which worked.
Ricardo please fix.

Ricardo M. Correia c0ce3b40f2 Reimplement user kthreads based on pthread thread specific data.
This resolves previous scalabily concerns about the cost of calling
curthread which previously required a list walk.  The kthread address
is now tracked as thread specific data which can be quickly returned.

Brian Behlendorf 864e44e7e0 Provide correct kthread API semantics using pthreads.
The intent here is to fully remove the previous Solaris thread
implementation so we don't need to simulate both Solaris kernel
and user space thread APIs.  The few user space consumers of the
thread API have been updated to use the kthread API.  In order
to support this we needed to more fully support the kthread API
and that means not doing crazy things like casting a thread id
to a pointer and using that as was done before.  This first
implementation is not effecient but it does provide all the
corrent semantics.  If/when performance becomes and issue we
can and should just natively adopt pthreads which is portable.

Let me finish by saying I'm not proud of any of this and I would
love to see it improved.  However, this slow implementation does
at least provide all the correct kthread API semantics whereas
the previous method of casting the thread ID to a pointer was
dodgy at best.

Brian Behlendorf 1ab1b8502b Stop the kthread/thread/pthread mixing and matching insanity. Update all
code to only use the kthread API regardless of if it is compiled in the
kernel or user space.  The kthread API will be layered on top of pthreads
as best as possible in zfs_context, this is non optimal but much clearer.
