adapted to the netbsd-10 branch.

dtrace/i386: Need machine/cpufunc.h for x86_read_flags and rcr2.

Fix DIAGNOSTIC build; replace FreeBSD-specific function with ours.

better to put this (<sys/proc.h>) in the dtrace header where the definitions
are needed.

The (dtrace version of) <sys/proc.h> is needed for kthread_t
(same as the amd64 version).   This should fix (one of) the
current i386 build breakages.

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().

apply changes equivalent to freebsd r256822, r267759 and r298171:
fix the dtrace "args" variable to return correct values.
simplify the invop handlers a bit by changing the second argument
from a pointer into the stack to a pointer to the trapframe.

reduce diff to freebsd:
rename "xcpu" back to "cpu" now that the conflicting global variable
has been renamed out of the way.  this also fixes some cases
where references to the local variable "cpu" had not been renamed
and thus were accidentally referring to the former global "cpu".

fix a shadow variable warning.

Remove a couple of zero length kmem_frees.

It should fix at least one crash when unloading the dtrace module,
possibly many others.

As this file seems to be a port specific we don't need to check
for "__i386__.

Fix the build:
1.) "ifdef-out" unused functions and global variables.
2.) Include "x86/include/cpu_counter.h" for amd64 and i386 to get the
    prototype of "cpu_frequency".

Apply NetBSD changes to DTrace.

Add the FreeBSD 8-RC1 changes for DTrace.
