This is the equivalvent of

adapted to the netbsd-10 branch.

dtrace: add support for SMAP

Add support in dtrace for SMAP, so that actions like copyinstr() work.
It would be better if dtrace could use the SMAP_* hotpatch macros directly,
but the hotpatching code does not currently operate on kernel modules,
so we'll use some tiny functions in the base kernel for now.

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().

Sync with HEAD

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.

Import fix from FreeBSD - see [1], [2] references below...

Fix DTrace's panic() action.

It would previously call into some unfinished Solaris compatibility code
and return without actually calling panic(9). The compatibility code is
unneeded, however, so just remove it and have dtrace_panic() call vpanic(9)
directly.

Fixes immediate problem in PR-51265.  However, this now reveals another
redefined symbol 'strpbrk' in the required module "solaris".

plus a few netbsd-specific tweaks from me.
fixes PR 50790.

make dtrace compile on amd64.
