Sync libsysdecode, kdump, and truss with head (aside from changes such
as ino64 that are not applicable to 11).

319493:
Decode the arguments passed to __cap_rights_get() and cap_rights_limit().

319509:
Decode the argument passed to cap_getmode().

The returned integer value is output.

319520:
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().

319595:
Decode arguments to dup, dup2, getdirentries, pread, and pwrite.

• dup and dup2 print fd arguments in decimal.
• pread and pwrite are similar to read and write with the addition of the file offset.
• getdirentries displays the output entries as a string for now and also prints the value returned in *basep. Eventually the buffer for getdirentries should perhaps be decoded as an array of dirent structures.

319677:
Decode arguments to ACL related system calls.

This only decodes the raw arguments but not the contents of the struct acl
objects.

319679:
Decode arguments passed to extended attribute related system calls.

The cmd argument passed to extattrctl() is not decoded as a string constant
but is just printed in hex. The value is filesystem-specific but in
practice is only used with UFS1 filesystems.

319680:
Decode arguments to minherit().

319681:
Decode arguments to mlock(), mlockall(), and munlock().

319688:
Decode flags passed to mount(), nmount(), and unmount().

319689:
Decode arguments passed to msync().

319761:
Fix decoding of setpriority() arguments.

The PRIO_* 'which' value is stored in the first argument to setpriority(2),
not the last. While here, decode the arguments to getpriority(2).

319762:
Decode arguments to getpriority() and setpriority().

319763:
Decode the arguments to ptrace().

This does not decode structures returned by ptrace().

319764:
Decode the arguments to quotactl().

319765:
Improve decoding of RB_AUTOBOOT in the 'howto' argument to reboot().

The reboot() system call accepts a mode (RB_AUTOBOOT, RB_HALT, RB_POWEROFF,
or RB_REROOT) as well as zero or more optional flags in 'howto'.
However, RB_AUTOBOOT was only displayed if 'howto' was exactly 0.
Combinations like 'RB_AUTOBOOT | RB_DUMP' were decoded as 'RB_DUMP'.
Instead, imply that RB_AUTOBOOT was specified if none of the other "mode"
flags were specified.

319766:
Decode the 'howto' argument to reboot().

319767:
Decode arguments to rtprio_thread() (same as rtprio()).

319768:
Decode arguments to rtprio() and rtprio_thread().

320010:
Decode arguments to sched_* family of system calls.

This includes decoding both scheduler policy constants and the sched_param
structure for sched_get_priority_max(), sched_get_priority_min(),
sched_getparam(), sched_getscheduler(), sched_rr_get_interval(),
sched_setparam(), and sched_setscheduler().

322899:
Decode arguments passed to thr_set_name().

322959:
Decode extra signal information for caught signals.

Decode fields from the siginfo_t stored in the PT_LWPINFO structure when a
signal is caught by a traced process. This includes the signal code
(si_code) as well as additional members such as si_addr, si_pid, etc.

323020:
Trim stale prototype for ioctlname().

323021:
Decode signal information returned by system calls.

Specifically, decode the siginfo structure returned by sigtimedwait(),
sigwaitinfo(), and wait6(). While here, also decode the signal number
returned in the second argument to sigwait().

323151:
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.
