xscale: trace buffer remains enabled until explicitly disabled

Hi everyone,

Since a call went out for patches... been sitting on this for months.  For some
reason, the xscale trace buffer is automatically disabled as soon as a break
occurs and the trace data is collected.  This patch was a result of the
frustration of always re-enabling it, or else hitting a breakpoint and checking
the trace data, only to discover that I forgot to re-enable it before resuming.
Don't see why it should work this way.  There is no run-time penalty, AFAIK.

Along the way, I also cleaned up a little by removing the ugly practice of
recording wrap mode by setting the fill count variable to "-1", replacing it
with an enum that records the trace mode.

I've been using this for months.  Comments, criticisms gratefully received.

Mike
