dtrace: re-fix aggregations to report from all online CPUs

Reapply the fix to dt_status() from rev 1.10
("Don't return success when the target CPU is offline")
which was lost in rev 1.12 ("sync with FreeBSD").

The FreeBSD version that we have been using since then does run on NetBSD
but always reports that CPU 0 is online and all other CPUs are offline,
because the sysctl that it uses does not exist on NetBSD.

dtrace: remove unnecessary fflush()

      dtrace: remove unnecessary fflush()

      This call was added back in the early days of dtrace porting and
      no one knows why anymore.  The extra flushing causes lots of
      unnecessary CPU overhead when a script produces lots of output,
      as well as easily losing output because the command can't keep up.

Adjust string sizes

Sync with HEAD

merge a new version of the CDDL dtrace and ZFS code.
this changes the upstream vendor from OpenSolaris to FreeBSD,
and this version is based on FreeBSD svn r315983.

in addition to the 10 years of improvements from upstream,
this version also has these NetBSD-specific enhancements:
 - dtrace FBT probes can now be placed in kernel modules.
 - ZFS now supports mmap().

import new CDDL dtrace and ZFS code from FreeBSD svn r315983.

sync with FreeBSD

Fix dtrace build error with gcc 4.8 on i386 and arm

_ILP32 is required by dt_popc.

The fix is inspired by FreeBSD.

Don't return success when the target CPU is offline

dt_status originally expected the behavior.

This fixes a segfault happens in dt_aggregate_go (a user of dt_status)
that depends on the behavior.

check and fix printf formats, negative array indices, uninitialized variables,
shadowed variables.

Rebase to HEAD as of a few days ago.

sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

kill sprintf

Replace llx with PRIx64 and some llu with PRIu64 in format strings.

resync with head

sync with head

Include "sys/ioctl.h" for the prototype of ioctl(2) which fixes the build.

make aggregate work for > 1 cpus

Merge NetBSD local changes to new zfs version 22 sources.

Import new Opensolaris sources for zfs/dtrace.

Opensolaris mercurial changeset: 11751:58c0c8f4305f

Apply NetBSD changes to DTrace.

Ok with core@.

Add the FreeBSD 8-RC1 changes for DTrace.

Ok with core@.

Import the rest of Opensolaris 20081117 needed for DTrace. No conflicts
with ZFS.
