sh: Write as much into the heredoc pipe as possible, to avoid forking.

Use non-blocking I/O to write as much as the pipe will accept (often 64K,
but it can be as little as 4K), avoiding the need for the ugly PIPESIZE
constant. If PIPESIZE was set too high, a deadlock would occur.
Replace access to /dev/random with the kernel pseudo-random number
source sysctl(KERN_ARND) and remove the fallback code.

Replace the remaining uses of vm_radix_node_page() by vm_radix_isleaf() and
vm_radix_topage().  This transformation eliminates some unnecessary
conditional branches from the inner loops of vm_radix_insert(),
vm_radix_lookup{,_ge,_le}(), and vm_radix_remove().

Simplify the control flow of vm_radix_lookup_{ge,le}().

drm and i915: Left-shift iic_msg.slave at creation time

This is required because, in the radeon driver, we can't left-shift in a
central place, like it was done in the i915 driver.

spa_open_common: fix argument to zvol_create_minors

Prior to r248571 spa_open was always called with a bare pool name,
but now it is called with a dataset name instead (spa_lookup handles
that).
So, when a ZFS root is mounted spa_open is called with a name of a root
dataset, which can very well be different from the pool name.
But zvol_create_minors should be called with the pool name, because it
performs a recursive traversal of all datasets under the name to find
all those that are volumes.

Since ATA_CAM mode has no implemented support for serializing access to the
different ATA channels, required for acard and pc98 ATA controllers, block
access to second channels of both, hoping that one working channel is better
then none.  I have an idea how that support could be implemented, but I have
no hardware to work on that.

IFP4 change 222074.

Introduce an explicit close of the output descriptor so that work done
on close is accounted for in the summary output triggered at exit
(implicit close()s occur after atexit() hooks).

This is useful because some devices such as cfi(4) may perform
signficant work after a close occurs (e.g. erasing and rewriting a
block of flash).
