- Update to strace 5.6
  * Changes in behaviour
    * Messages about unknown tracees are now subject to the strace's quietness
      setting (-q/--quiet).
    * If -A option is provided without -o, or -S option without -c/-C, a warning
      about its uselessness is printed now.
    * The usage of --seccomp-bpf without -f has no effect now.
  * Improvements
    * Every short option now has a long option alias, which also has enabled
      the following improvements:
      * Ability to use human-readable settings for -I/--interruptible,
	-D/--daemonize options.
      * Ability to silence specific messages using -e quiet/--quiet qualifier
	(an alias for the -q option), including those that couldn't be silenced
	previously (path resolution messages and "superseded by execve").
      * Ability to specify selected fd decoding features using
	-e decode-fds/--decode-fds qualifier (an alias for the -y option).
      * Ability to set precision for the absolute timestamp, relative timestamp,
	and syscall time output (using --absolute-timestamps,
	--relative-timestamps, and --syscall-times options, respectively).
    * Implemented ability to select the set of displayed columns in the call
      summary output (-U/--summary-columns option).
    * Implemented ability to sort on any summary column.
    * Implemented ability to show information about minimum and maximum call
      duration in the call summary output (addresses Debian bug #240945).
    * Implemented printing of PIDs associated with pidfds in -yy mode.
    * Implemented PTRACE_GETREGS API support on hppa, sh, sh64, and xtensa.
    * Improved performance of libdw-based stack traces printing by implementing
      a symbol-to-address cache.
    * Implemented decoding of openat2 and pidfd_getfd syscalls. (forwarded request 791997 from Andreas_Schwab)
