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.

accepts a third argument to
.Xr fcntl 2
and
.Dv false
if it does not.
.Sh RETURN VALUES
The

The text description lists the C macros for field values joined by pipe
.Sq |
characters matching the format used in C source code.
Most of the values decoded by these functions are passed as arguments to
system calls,
though some of these values are used internally in the kernel.
.Pp
Each function writes the text description to
.Fa fp .
The second argument should contain the integer value to be decoded.
The
.Fa rem
argument is set to the value of any bits that were not decoded
.Pq bit fields that do not have a corresponding C macro .
.Fa rem
may be set to
.Dv NULL
if the caller does not need this value.
Each function returns
.Dv true
if any bit fields in the value were decoded and
.Dv false
if no bit fields were decoded.
.Pp
Most of these functions decode an argument passed to a system call:

.Sh SYNOPSIS
.In sys/types.h
.In stdbool.h
.In sysdecode.h
.Ft bool
.Fn sysdecode_quotactl_cmd "FILE *fp" "int cmd"
.Sh DESCRIPTION
The
.Fn sysdecode_quotactl_cmd
function outputs a text description of the
.Fa cmd
argument to
.Xr quotactl 2
to the stream
.Fa fp .
The description is formatted as an invocation of the
.Dv QCMD
macro defined in the
.In ufs/ufs/quota.h
header.
.Pp
The function first computes the primary and secondary values used by
.Dv QCMD
to construct
.Fa cmd .
If the primary command value does not represent a known constant,
.Fn sysdecode_quotactl_cmd
does not generate any output and returns
.Dv false .
Otherwise,
.Fn sysdecode_quotactl_cmd
outputs text depicting an invocation of
.Dv QCMD
with the associated constants for the primary and secondary command values
and returns
.Dv true .
If the secondary command values does not represent a known constant,
its value is output as a hexadecimal integer.
.Sh RETURN VALUES
The
.Nm sysdecode_quotactl_cmd
function returns
.Dv true
if it outputs a description of
.Fa cmd
and
.Dv false
if it does not.
.Sh EXAMPLES
The statement
.Pp
.Dl sysdecode_quotatcl_cmd(stdout, QCMD(Q_GETQUOTA, USRQUOTA);
.Pp
outputs the text
.Dq QCMD(Q_GETQUOTA, USRQUOTA)
to standard output.

object associated with an instance of signal
.Fa sig .
The text description contains the name of the C macro whose value matches

The

function returns a text description of the socket option name passed in the
.Fa optname
argument to
.Xr getsockopt 2 .
.Fn sysdecode_sockopt_name
takes the socket option
.Fa level
as well as the option name to uniquely identify the option.
.Sh SEE ALSO
.Xr sysdecode_sockopt_level 3
.Sh BUGS
Socket option levels and names are protocol-specific.
Both
.Fn sysdecode_sockopt_level
and
.Fn sysdecode_sockopt_name
should possibly accept the protocol family as an additional argument.

# mkioctls is a special-purpose script, and works fine as it is
# now, so it remains independent. The idea behind how it generates
# its list was heavily borrowed here.
#
# Some functions here are automatically generated. This can mean
# the user will see unusual kdump output or errors while building
# if the underlying .h files are changed significantly.
#
# Key:
# AUTO: Completely auto-generated with either the "or" or the "switch"
# method.
# AUTO - Special: Generated automatically, but with some extra commands
# that the auto_*_type() functions are inappropriate for.
# MANUAL: Manually entered and must therefore be manually updated.
