48e6891944 The vmresult table was missing most of the values apart from two due to
extra "_" in the names we grep for. Add the "_" to the pattern.

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().

39a3a4386a Decode pathconf() names, *at() flags, and sysarch() numbers in libsysdecode.
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.

87d18efc7b Follow-up r308602: Don't add missing headers to .depend.tables.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.

ee8aa41dca Decode the 'who' argument passed to getrusage().
Add a new sysdecode_getrusage_who() which decodes the RUSAGE_* constant
passed as the first argument to getrusage().  Use this function in both
kdump and truss to decode the first argument to getrusage().

aa9bddf0a8 Fix libsysdecode vmprot flag decoding
Fix the regex used to find vmprot table entries and add the missing include.

This fixes kdumps output of PFLT arguments which would previously look like:
5202 101546 ktrace   PFLT  0x5ae000 0x2<><invalid>2

They now display correctly:
5202 101546 ktrace   PFLT  0x5ac000 0x2<VM_PROT_WRITE>

48f7957436 Update libsysdecode for getfsstat() 'flags' argument changing to 'mode'.
As a followup to r310638, update libsysdecode (and kdump) to decode the
'mode' argument to getfsstat().  sysdecode_getfsstat_flags() has been
renamed to sysdecode_getfsstat_mode() and now treats the argument as an
enumerated value rather than a mask of flags.

9289f547a2 Move mksubr from kdump into libsysdecode.
Restructure this script so that it generates a header of tables instead
of a source file.  The tables are included in a flags.c source file which
provides functions to decode various system call arguments.

For functions that decode an enumeration, the function returns a pointer
to a string for known values and NULL for unknown values.

For functions that do more complex decoding (typically of a bitmask), the
function accepts a pointer to a FILE object (open_memstream() can be used
as a string builder) to which decoded values are written.  If the
function operates on a bitmask, the function returns true if any bits
were decoded or false if the entire value was valid.  Additionally, the
third argument accepts a pointer to a value to which any undecoded bits
are stored.  This pointer can be NULL if the caller doesn't care about
remaining bits.

Convert kdump over to using decoder functions from libsysdecode instead of
mksubr.  truss also uses decoders from libsysdecode instead of private
lookup tables, though lookup tables for objects not decoded by kdump remain
in truss for now.  Eventually most of these tables should move into
libsysdecode as the automated table generation approach from mksubr is
less stale than the static tables in truss.

Some changes have been made to truss and kdump output:
- The flags passed to open() are now properly decoded in that one of
  O_RDONLY, O_RDWR, O_WRONLY, or O_EXEC is always included in a decoded
  mask.
- Optional arguments to open(), openat(), and fcntl() are only printed
  in kdump if they exist (e.g. the mode is only printed for open() if
  O_CREAT is set in the flags).
- Print argument to F_GETLK/SETLK/SETLKW in kdump as a pointer, not int.
- Include all procctl() commands.
- Correctly decode pipe2() flags in truss by not assuming full
  open()-like flags with O_RDONLY, etc.
- Decode file flags passed to *chflags() as file flags (UF_* and SF_*)
  rather than as a file mode.
- Fix decoding of quotactl() commands by splitting out the two command
  components instead of assuming the raw command value matches the
  primary command component.

In addition, truss and kdump now build without triggering any warnings.
All of the sysdecode manpages now include the required headers in the
synopsis.
