[PATCH v3 3/4] Deprecate frame_stop_reason_string.

[Andrew Burgess <aburgess@broadcom.com>]

Patch #4 adds frame specific stop reason strings.  It is better to use that
string rather than the existing generic stop reason string.  This patch
renames frame_stop_reason_string to deprecated_frame_stop_reason_string and
updates all the call sites to use the deprecated name.

Patch #4 adds the new frame specific stop reason, and some uses of the
deprecated funciton will be moved to this new API, however, in the python
and guile scripting API we expose a function that converts the stop reason
code into a string, without a frame, this will be harder to convert to the
new API and so I have currently left using the
deprecated_frame_stop_reason_string function.

This patch only makes sense if patch #4 is approved, but does this look ok?

Thanks,
Andrew
