  Log Message:
  -----------
  trace: move qemu_trace_opts to trace/control.c

The patch also creates trace_opt_parse() helper in trace/control.c to reuse
this code in next patches for qemu-nbd and qemu-io.

The patch also makes trace_init_events() static, as this call is not used
outside the module anymore.

  -----------
  trace: enable tracing in qemu-io

Moving trace_init_backends() into trace_opt_parse() is not possible. This
should be called after daemonize() in vl.c.

  trace: enable tracing in qemu-nbd

Please note, trace_init_backends() must be called in the final process,
i.e. after daemonization. This is necessary to keep tracing thread in
the proper process.

  qemu-img: move common options parsing before commands processing

This is necessary to enable creation of common qemu-img options which will
be specified before command.

The patch also enables '-V' alias to '--version' (exactly like in other
block utilities) and documents this change.

The command will work this way:

[Quote "qcow2*" to protect against shell globbing as suggested by Eric
Blake <address@hidden>.

Adds two events to trace syscalls in syscall emulation mode (*-user):

  the syscall number and arguments.

* guest_user_syscall_ret: Emitted after the syscall is emulated;
  contains the syscall number and return value.
