I have no idea what this does (and until now that it even existed), but
apparently it needs this entry changed for the MSG_TLSAPPDATA, since
it is kernel only.
Modern debuggers and process tracers use ptrace() rather than procfs
for debugging. ptrace() has a supserset of functionality available
via procfs and new debugging features are only added to ptrace().
While the two debugging services share some fields in struct proc,
they each use dedicated fields and separate code. This results in
extra complexity to support a feature that hasn't been enabled in the
default install for several years.

The default package use to be FreeBSD-runtime but it should only contain
binaries and libs enough to boot to single user and repair the system, it
is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

r349369 removed IP_MIN_MEMBERSHIPS and IPV6_MIN_MEMBERSHIPS, and r349893
removed TCP_RACK_SESS_CWV. libsysdecode lacked dependencies to trigger a
rebuild of tables.h.
Add explicit dependencies as a workaround to address these specific
cases; a holistic solution is still needed.

There was an additional + after the {6} which is apparently ignored by the
FreeBSD regex implementation but was giving me an error when compiling on
MacOS.
While changing this also make sure that tables.h is not created if mktables
fails. The current rule would create a partial tables.h which causes following
incremental builds to use that broken file and fail with an unrelated
compilation error or even succeed even though they shouldn't.

Using find -s will not work with the Linux or MacOS find command. We pipe
to sort instead since the only real requirement here is that the order
stays the same. While I am touching this file I also fixed a `==` construct

In order to let truss(8) support tracing of 32-bit CloudABI
applications, we need to add a new ABI type to libsysdecode. We can
reuse the existing errno mapping table. Also link in the cloudabi32
system call table to translate system call names.
While there, remove all of the architecture ifdefs. There are not
needed, as the CloudABI data types and system call tables build fine on
any architecture. Building this unconditionally will make it easier to
do tracing for different compat modes, emulation, etc.

- Add a new KTR_STRUCT_ARRAY ktrace record type which dumps an array of
structures.
The structure name in the record payload is preceded by a size_t
containing the size of the individual structures. Use this to
replace the previous code that dumped the kevent arrays dumped for
kevent(). kdump is now able to decode the kevent structures rather
than dumping their contents via a hexdump.
One change from before is that the 'changes' and 'events' arrays are
not marked with separate 'read' and 'write' annotations in kdump
output. Instead, the first array is the 'changes' array, and the
second array (only present if kevent doesn't fail with an error) is
the 'events' array. For kevent(), empty arrays are denoted by an
entry with an array containing zero entries rather than no record.
- Move kevent decoding tables from truss to libsysdecode.
This adds three new functions to decode members of struct kevent:
sysdecode_kevent_filter, sysdecode_kevent_flags, and
sysdecode_kevent_fflags.
kdump uses these helper functions to pretty-print kevent fields.
- Move structure definitions for freebsd11 and freebsd32 kevent
structures to <sys/event.h> so that they can be shared with userland.
The 32-bit structures are only exposed if _WANT_KEVENT32 is defined.
The freebsd11 structures are only exposed if _WANT_FREEBSD11_KEVENT is
defined. The 32-bit freebsd11 structure requires both.
- Decode freebsd11 kevent structures in truss for the compat11.kevent()
system call.
- Log 32-bit kevent structures via ktrace for 32-bit compat kevent()
system calls.
- While here, constify the 'void *data' argument to ktrstruct().

Move tables that were previously in truss over to libsysdecode. truss
output is unchanged, but kdump has been updated to decode these fields.
In addition, sysdecode_sysarch_number() should support all platforms
whereas the old table in truss only supported x86.
Only filter out the PF ioctls if we're building without pf support.
Until now those were always filtered out, so truss did not show symbolic

This was originally added so that only one of diskmbr.h or diskpc98.h
was chosen and is no longer needed after PC98's removal. However, the
special handling was also broken as it effectively prevented the decoding
of ioctls declared in other headers such as <sys/disk.h> or
<sys/disklabel.h>.
This also avoids an error from egrep when a header is missing. This can happen
with something like WITHOUT_BLUETOOTH set when searching for
$include_dir/netgraph/bluetooth/include/ng_btsocket.h. The warning was
not an error (from set -e) due to being on the left side of a pipe. Now the
all_headers list is only filled with existing headers.
