Coverity uses several heuristics to identify when one case statement
legitimately falls through into the next, and a comment as the final item in a
case statement is one heuristic (the assumption being that it is a
justification for the fallthrough).
Use this to perform an audit of defects and hide the legitimate fallthroughs.
There are two bugfixes identified in the audit, both minor:
* 'n' command line handling for gtracestat
* BKSPC handling in xentop
All other identified defaults are legitimate fallthoughs

Check for a curses compatible library (curses or ncurses basically).
One of those is needed to compile Xen tools (gtraceview and xentop).
Modify Makefiles/sources to use configure output (fetch CURSES_LIBS
from tools/Tools.mk and header to include from tools/config.h)

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.
