[PATCH] More NEWS for 7.2

This patch adds notes for overlooked user-visible changes in 7.2. The diff is for the 7.2 branch, but I'll paste into trunk as well, once any wording glitches have been sorted out. Please don't make me define all the terms. :-)

    remote packets have been defined to support static tracepoints, see
    the "New remote packets" section below.
+ * Better reconstruction of tracepoints after disconnected tracing
+   GDB will attempt to download the original source form of tracepoint
+   definitions when starting a trace run, and then will upload these
+   upon reconnection to the target, resulting in a more accurate
+   reconstruction of the tracepoints that are in use on the target.
+ * Observer mode
+   You can now exercise direct control over the ways that GDB can
+   affect your program.  For instance, you can disallow the setting of
+   breakpoints, so that the program can run continuously (assuming
+   non-stop mode).  In addition, the "observer" variable is available
+   to switch all of the different controls; in observer mode, GDB
+   cannot affect the target's behavior at all, which is useful for
+   tasks like diagnosing live systems in the field.
+ * The new convenience variable $_thread holds the number of the
+   current thread.

    a directory.
