Trace events aren't designed to be multi-lines.
Few format use the newline character: remove it
and forbid further uses.

Philippe Mathieu-Daudé (5):
  backends/tpm: Remove newline character in trace event
  hw/sh4: Remove newline character in trace events
  hw/usb: Remove newline character in trace events
  hw/vfio: Remove newline character in trace events
  tracetool: Forbid newline character in event format
