[RFC][PATCH] - Fix pretty-printers which call the inferiors, mi-interface crashs

Hi,
as described in Bug 17437 the mi interface corrupts cached frames in
the list_arg_or_local function of mi-cmd-stack.c when a pretty-printer
calls a function of the inferior. To prevent this the frame_id is stored
and used to restore the frame after calling list_arg_or_local
- MI regressions were run and no effect through the patch was seen

Is this patch okay?

BR, Thilo
