7be9a3b453 ctfconvert: Rip out STABS support
It is unused on FreeBSD and complicates some efforts to modify the CTF

f339a3ef63 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.

5f2aca8394 Disable clang 14 warning about bitwise operators in zstd
Parts of zstd, used in openzfs and other places, trigger a new clang 14
-Werror warning:

```
sys/contrib/zstd/lib/decompress/huf_decompress.c:889:25: error: use of bitwise '&' with boolean operands [-Werror,-Wbitwise-instead-of-logical]
                        (BIT_reloadDStreamFast(&bitD1) == BIT_DStream_unfinished)
                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```

While the warning is benign, it should ideally be fixed upstream and
then vendor-imported, but for now silence it selectively.

30ec3138ed dtrace: Disable getf() as it is broken on FreeBSD
getf() on FreeBSD calls _sx_slock(), _sx_sunlock() and fget_locked().
Furthermore, it does not set the per-core fault flag, meaning it
usually ends up in a double fault panic once getf() does get called,
especially from fbt.

Reviewing the DTrace Toolkit + a number of other scripts scattered
around FreeBSD, I have not been able to find one use of getf(). Given
how broken the implementation currently is, we disable it until it
can be implemented properly.

Also comment out a test in aggs/tst.subr.d for getf().

105fd928b0 libctf: Improve check for duplicate SOU definitions in ctf_add_type()
When copying a struct or union from one CTF container to another,
ctf_add_type() checks whether it matches an existing type in the
destination container.  It does so by looking for a type with the same
name and kind as the new type, and if one exists, it iterates over all
members of the source type and checks whether a member with matching
name and offset exists in the matched destination type.  This can
produce false positives, for example because member types are not
compared, but this is not expected to arise in practice.  If the match
fails, ctf_add_type() returns an error.

The procedure used for member comparison breaks down in the face of
anonymous struct and union members.  ctf_member_iter() visits each
member in the source definition and looks up the corresponding member in
the desination definition by name using ctf_member_info(), but this
function will descend into anonymous members and thus fail to match.
Fix the problem by introducing a custom comparison routine which does
not assume member names are unique.  This should also be faster for
types with many members; in the previous scheme, membcmp() would perform
a linear scan of the desination type's members to perform a lookup by
name.  The new routine steps through the members of both types in a
single loop.

  zpool_influxdb produces InfluxDB-line-protocol-compatible metrics from
  zpools.  Like the zpool command, zpool_influxdb reads the current pool
  status and statistics.  Unlike the zpool command which is intended for
  humans, zpool_influxdb formats the output in the InfluxDB line protocol.
  The expected use is as a plugin to a metrics collector or aggregator,
  such as Telegraf.

zpool_influxdb is installed into /usr/libexec/zfs/

410556f1f1 libctf: Fix an out-of-bounds read in ctf_lookup_by_name()
When prefixes such as struct, union, etc. are compared with the current
type (e.g. struct foo), a comparison is made with the prefix.  The code
currently assumes that every type is a valid C type with a prefix,
however at times, garbage ends up in this function causing an
unpredictable crash with DTrace due to the isspace(*p) call or
subsequent calls. An example that I've seen of this is the letter 's'
being passed in, comparing true with struct as the comparison size was
(q - p) == 1, but then we increment p with the length of "struct",
resulting in an out of bounds read.

123ae3045d build: remove LIBPTHREAD/LIBTHR build options
WITHOUT_LIBTHR has been broken for a little over five years now, since the
xz 5.2.0 update introduced a hard liblzma dependency on libthr, and building
a useful system without threading support is becoming increasingly more
difficult.

Additionally, in the five plus years that it's been broken more reverse
dependencies have cropped up in libzstd, libsqlite3, and libcrypto (among
others) that make it more and more difficult to reconcile the effort needed
to fix these options.

Remove the broken options.

96fbe51956 When copying types from one CTF container to another, ensure that we
encode 0-length (i.e. "") structure and union member names as offset 0.
This ensures that we don't confuse other parts of the CTF code which
expect this encoding.

This resolves a Dtrace error resolving members of anonymous structs/unions
within the (struct mbuf) type which some users were seeing after r366908.

While here, update the code in ctf_add_generic() to encode 0-length type
names as offset 0.

3cbb4cc200 When copying types from one CTF container to another, ensure that we
always copy intrinsic data types before copying bitfields which are
based on those types. This ensures the type ordering in the destination
CTF container matches the assumption made elsewhere in the CTF code
that instrinsic data types will always appear before bitfields based on
those types.

This resolves the following error message some users have seen after
r366908:
    "/usr/lib/dtrace/ipfw.d", line 121: failed to copy type of 'ip6p':
    Conflicting type is already defined

73734d6eb1 Add missing includes of src.opts.mk
Without this "SUBDIR.${MK_TESTS}=tests" would always expand to
"SUBDIR.=tests" resulting in the tests not being built.

7cc42f6d25 Do a sweep and remove most WARNS=6 settings
Repeating the default WARNS here makes it slightly more difficult to
experiment with default WARNS changes, e.g. if we did something absolutely
bananas and introduced a WARNS=7 and wanted to try lifting the default to
that.

Drop most of them; there is one in the blake2 kernel module, but I suspect
it should be dropped -- the default WARNS in the rest of the build doesn't
currently apply to kernel modules, and I haven't put too much thought into
whether it makes sense to make it so.
