Title:
  Unnecessary events option of the trace argument with UST backend

Status in QEMU:
  Expired

Bug description:
  When running configure with the --enable-trace-backends=ust option and 
compiling. 
  The user should not have to specify a the "events" and "file" options because 
they are not used with that tracing framework.

  Right now, in order the use this option the need to specify a dummy
  events file.

  This fails:
  $> qemu-system-x86_64 -hda debian_wheezy_amd64_standard.qcow2 -trace -m 512
  qemu-system-x86_64: -trace -m: Invalid parameter '-m'

  This works:
  $> qemu-system-x86_64 -hda debian_wheezy_amd64_standard.qcow2 -trace 
events=dummy-events.txt -m 512
  VNC server running on `127.0.0.1:5900'

  I am using version:
  $> qemu-system-x86_64 --version
