This is only a partial merge of respective ZFS infrastructure changes.
At this moment FreeBSD kernel has no those crypto algorithms, so the
parts of the code to enable them are commented out.  When they are
implemented, it will be trivial to plug them in.

 - video https://www.youtube.com/watch?v=iY44jPMvxog
 - manpage changes (for zfs resume -s and zfs send -t)
 - 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>"

3142b37664 Have lockstat(1) trace locks by name rather than by address.
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.

bd81e07d27 Re-apply r274569. It was reverted in r276848 since that appeared to fix
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.

and the indirect block was not cached. We should prefetch upcoming indirect
blocks to avoid having to go to disk and blocking the restore_write().

stream does not mark it as a clone.

7e518a6648 - Use an explicit "depends_on module kernel" guard in DTrace libraries that
reference types defined in the kernel. Otherwise dtrace(1) expects to find
  CTF definitions for all referenced types, which is not very reasonable
  when it is being used in a build environment. This was previously worked
  around by adding "-x nolibs" to dtrace -h or -G invocations, but as of
  r283025, dtrace(1) actually handles dependencies properly, so this is no
  longer necessary.
- Remove "pragma ident" directives from DTrace libraries, as they're being
  phased out upstream as well.

a565264d3c zfs clone should not mount the clone if canmount == noauto
Creation of a new filesystem does not imply an intent to mount it.

Since canmount property is not inherited and its default value is 'on',
the only scenario where this matters is zfs clone -o canmount=noauto.
zfs create -o canmount=noauto already does not mount the new filesystem.

076dd8eb2e several lockstat improvements
0. For spin events report time spent spinning, not a loop count.
While loop count is much easier and cheaper to obtain it is hard
to reason about the reported numbers, espcially for adaptive locks
where both spinning and sleeping can happen.
So, it's better to compare apples and apples.

1. Teach lockstat about FreeBSD rw locks.
This is done in part by changing the corresponding probes
and in part by changing what probes lockstat should expect.

2. Teach lockstat that rw locks are adaptive and can spin on FreeBSD.

3. Report lock acquisition events for successful rw try-lock operations.

4. Teach lockstat about FreeBSD sx locks.
Reporting of events for those locks completely mirrors
rw locks.

5. Report spin and block events before acquisition event.
This is behavior documented for the upstream, so it makes sense to stick
to it.  Note that because of FreeBSD adaptive lock implementations
both the spin and block events may be reported for the same acquisition
while the upstream reports only one of them.

d4a115af56 Move siftr-related definitions out of tcp.d and into a separate library
which declares a dependency on siftr(4). This is necessitated by a
reference to struct pkt_node, which is defined in siftr(4): otherwise,
dtrace(1) will return an error during startup if siftr.ko is not loaded.

f65e699c36 As dtrace(1) processes D libraries under /usr/lib/dtrace, the compiler may
return an error if one of the depends_on directives in a library is not
satisfied. In this case, libdtrace is supposed to ignore the library and
carry on. However, the remainder of the library may still be buffered by
the lexer, causing libdtrace to erroneously continue processing it on the
next call to yyparse(). Fix this by explicitly flushing the input buffer
each time the compiler state is reset.

3e5645b78f ctf_add_type(): when looking up an integer or floating point type in the
list of pending dynamic type definitions, a match on the type name is not
sufficient - we need to compare the type encodings as well. For example,
bitfields have their own distinct type definitions which share the name of
the underlying integer type, and these types aren't generally
interchangeable.

This bug was causing the following libdtrace error when attempting to trace
the th_flags member of a struct tcphdr:

67cf27b70f libdtrace: add support for lazyload mode.
Passing "-x lazyload" to dtrace -G during compilation causes dtrace(1) to

during process startup. Instead, dtrace(1) will automatically discover and
create probes on the process' behalf when attaching.

41aeaf2a30 Replace dtest.pl, the upstream DTrace test suite harness, with a shell
script. This reimplementation is much simpler than dtest.pl and is more
amenable to being run under Kyua - dtest.pl writes error output to a
temporary directory that is deleted when the run finishes, making it hard
to debug test failures. This change also removes the test suite's dependency
on perl.

f810bf0eaf When copying a type from a source CTF container to a destination container,
ctf_add_type() first performs a by-name lookup of the type in the
destination container. If this lookup returns a forward declaration for an
enum, struct, or union, reset dst_type back to CTF_ERR, indicating that the
source type is not in fact present in the destination container. This
ensures that ctf_add_type() will also search the destination container's
dynamic type list for the source type.

Without this change, a pair of mutually recursive struct definitions could
cause infinite recursion in ctf_add_type() if the destination container
only contained forward declarations for the struct types: ctf_add_type()
recursively calls itself on each struct member's type, and the forward
declarations meant that the dynamic type list search would be skipped.

b0ee912984 CTF containers use the ctf_dtoldid field as a threshold type index which
indicates the range of type indices which have been committed to the
container by ctf_update(). However, the top bit of the dtd_type field is
not part of the type index; rather, it is a flag used to indicate that the
corresponding CTF container is a parent. This is why the maximum CTF type
index is 2^15 - 1 rather than 2^16 - 1. Therefore, this flag must be masked
off (using the CTF_TYPE_TO_INDEX macro) when comparing a type index with the
ctf_dtoldid field of a container.

This bug was causing libctf to erroneously free committed type definitions
in ctf_discard(). libdtrace holds some references to such types, resulting
in a use-after-free.

4ddbe5ac37 Add infrastructure to integrate the DTrace test suite with Kyua.
For each test category, we generate a script containing ATF test cases for
the tests under that category. Each test case simply runs dtest.pl (the
upstream test harness) with the corresponding test files. The exclude.sh
script is used to record info about tests which should be skipped or are
expected to fail; it is used to generate atf_skip and atf_expect_fail calls.
The genmakefiles.sh script can be used to regenerate the test makefiles when
new tests are brought it from upstream.

The test suite is currently not connected to the build as there is a small
number of lingering test issues which still need to be worked out. In the
meantime however, the test suite can be easily built and installed
manually from cddl/usr.sbin/dtrace/tests.

03a5f9f0fd Remove drti.o's dependency on libelf. This makes it possible to add DTrace
probes to userland programs and libraries without also needing to link
libelf.

dtrace -G places the __SUNW_dof symbol at the beginning of the DOF (DTrace
probe and provider metdata) section in the generated object file; drti.o
now just uses this symbol to locate the section. A complication occurs
when multiple dtrace-generated object files are linked together, since the
__SUNW_dof symbol defined in each file is global. This is handled by
using objcopy(1) to convert __SUNW_dof to a local symbol once drti.o has
been linked with the generated object file. Upstream, this is done using a
linker feature not present in GNU ld.
