Since fcmpset can fail without lock contention e.g. on arm, it was possible

called for all threads belonging to a procedure. Currently the first
thread in a procedure is kept around as an optimisation step and is
never freed. Because the first thread in a procedure is never freed
nor allocated, its destructor and constructor callbacks are never
called which means per thread structures allocated by dtrace and the
Linux emulation layers for example, might be present for threads which
don't need these structures.
This patch adds a thread construction and destruction call for the
first thread in a procedure.
Tested: dtrace, linux emulation

This is a first step to fix live LUN disabling. Before this change
any CTIOs held in a queue in time of disabling were just leaked.

Before this change XCOPY code could allocate memory in chunks up to 16-32MB
(VMware does XCOPY in 4MB chunks by default), that could be difficult for
VM subsystem to do due to KVA fragmentation, that sometimes created huge
allocation delays, blocking any I/O for respective LU for that time.
This change limits allocations down to TPC_MAX_IO_SIZE, which is 1MB now.
1MB is also not a cookie, but ZFS also can do that for large blocks, so
it should be less dramatic. As drawback this increases CPU overhead, but
it still look acceptable comparing to time consumed by ZFS read/write.

Users can use the new generic argument, -Q task_attr, to specify a task
attribute (simple, ordered, head of queue, aca) for the commands issued.
The the default is simple, which works with all SCSI devices that support
tagged queueing.
This will mostly be useful for debugging target behavior in certain
situations.
You can try it out by compiling CTL with CTL_IO_DELAY turned on (in
sys/cam/ctl/ctl_io.h) and then do something like this with one of the CTL
LUNs:
ctladm delay 0:0 -l done -t 10
camcontrol tur da34 -v
And at then before the 10 second timer is up, in another terminal:
camcontrol inquiry da34 -Q ordered -v
The Inquiry should complete just after the TUR completes. Ordinarily
it would complete first because of the delay injection, but because the
task attribute is set to ordered in this case, CTL holds it up until the
previous command has completed.
sbin/camcontrol/camcontrol.c:
Add the new generic argument, -Q, which allows the user to specify
a SCSI task attribute. The user can specify task attributes by
name or numerically.
Add a new task_attr arguments to SCSI sub-functions.

7504 kmem_reap hangs spa_sync and administrative tasks
illumos/illumos-gate@405a5a0f5chttps://github.com/illumos/illumos-gate/commit/405a5a0f5c3ab36cb76559467d1a62ba648bd80https://www.illumos.org/issues/7504
We see long spa_sync(). We are waiting to hold dp_config_rwlock for writer. Some
other thread holds dp_config_rwlock for reader, then calls arc_get_data_buf(),
which finds that arc_is_overflowing()==B_TRUE. So it waits (while holding
dp_config_rwlock for reader) for arc_reclaim_thread to signal arc_reclaim_waiters_cv.
Before signaling, arc_reclaim_thread does arc_kmem_reap_now(), which takes ~seconds.

This denotes changes which went in by accident in r313877.
On most production kernels both said parameters are zeroed and have nothing
reading them in either __mtx_lock_sleep or __mtx_unlock_sleep. Thus this change
stops passing them by internal consumers which this is the case.
Kernel modules use _flags variants which are not affected kbi-wise.
