[Xen-devel] [PATCH] xen pm trace utility cleanup

["Yu, Ke" <ke.yu@xxxxxxxxx>]

xenpm trace utility gtraceview cleanup

- add gtraceview help info on how to get raw data by xentrace
- make trace_exit_reason compiled in non-debug mode. trace_exit_reason can be 
enable/disabled by xentrace at runtime, so no need to disable it at build time.
