This allows one to enable DTrace probes relatively early during boot,
during SI_SUB_DTRACE_ANON, before dtrace(1) can invoked. The desired
enabling is created using dtrace -A, which writes a /boot/dtrace.dof
file and uses nextboot(8) to ensure that DTrace kernel modules are loaded
and that the DOF file describing the enabling is loaded by loader(8)
during the subsequent boot. The trace output can then be fetched with
dtrace -a.
With this commit, boot-time DTrace is only functional on i386 and amd64: on
other architectures, the high-resolution timer frequency is initialized
during SI_SUB_CLOCKS and is thus not available when the anonymous
tracing state is initialized. On x86, the TSC is used and is thus available
earlier.

Currently, zfs(8) and zpool(8) print "invalid type '(null)'" or similar
messages, if you pass in invalid types, sources or column names for "zfs
get", "zfs list" and "zpool get". This is because the commands use
getsubopt(3), and in case of failure, they print 'value', which is NULL
when sub options don't match.
They should print 'suboptarg' instead, which is the documented way to
get at the non-matching sub option value.

This allows to do a full (non-incremental send) and receive it as a clone
of an existing dataset. It can leverage nopwrite to share blocks with the
origin. This can be used to change the relationship of datasets on the
target. For example, maybe on the source you have:
A ---- B ---- C
And you have sent to the target a full of B, and the incremental B->C:
B ---- C
You later realize that you want to have A on the target. You will have to
do a full send of A, but nopwrite can save you space on the target if you
receive it as a clone of B, assuming that A and B have some blocks inxi
common:
B ---- C

r281257 added support for lazyload mode by allowing dtrace(1) to register
a DOF section on behalf of a traced process. This was implemented by
having libdtrace copy the DOF section into a heap-allocated buffer and
passing its address to the ioctl handler. However, DTrace uses the DOF
section address as a lookup key in certain cases, so the ioctl handler
should be given the target process' DOF section address instead. This
change modifies the ADDDOF handler to copy the DOF section in from the
target process, rather than from dtrace(1).
Fix zfs(8) not formatting due to wrong macro (Oc) in the syntax for the new
zfs set multiple dataset properties option.

- upcoming talk at the OpenZFS Developer Summit
The TL;DR is:
Use "zfs receive -s" to save the partially received state on failure.
On failure, get the receive token with "zfs get receive_resume_token <fs>"
Resume the send with "zfs send -t <token_value>"

Previously, lockstat(1) would use a lock's address as its identifier when
consuming data describing lock contention and hold events. After collecting
the requested data, it would use ksyms(4) to resolve lock addresses to
names. Of course, this doesn't work too well for locks contained in
dynamically-allocated memory. This change modifies lockstat(1) to trace the
lock names obtained from the base struct lock_object instead, leading to
output that is generally much more useful.
This change also removes the -c option, which is used to coalesce data for
locks in an array. It's not possible to support this option without also
tracing lock addresses, and since lock arrays in which the lock names are
distinct are not very common in FreeBSD, it's simpler to just remove the
option.

some ctfmerge crashes that started to occur on i386 weeks after r274569 was
committed. Some later investigation indicated that the crashes were caused
by malformed CTF info that led to a stack overflow. The issue with CTF
info in i386 kernels seems to have been resolved by r261246, which updated
libdwarf and libelf.
r274569 fixes a bug which caused duplicate types to appear in the kernel's
CTF info. This duplication generally does not cause problems when using
DTrace, but makes it easier to hit the limit of 2^15 - 1 distinct type
definitions in a CTF container.
