a8537fe404 Add MSG_TLSAPPDATA to lib/libsysdecode/mktables.
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.

59838c1a19 Retire procfs-based process debugging.
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.

Attempting to use ioctls on /proc/<pid>/mem to control a process will

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.

c5c5072bb0 Fix regex for extracting SHM_* values for libsysdecode
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.

87f69beea3 libsysdecode: Add a new ABI type, SYSDECODE_ABI_CLOUDABI32.
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.

ffb6607984 Decode kevent structures logged via ktrace(2) in kdump.
- 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().
