RFA (?) Annotate Level 3 patch

- Subject: RFA (?) Annotate Level 3 patch
The annotation frame-begin is not needed, per se, by Emacs (gdb-ui.el) but it
is used to determine that the I/O for the subprocess is now GDB, not the
program being debugged i.e as a stopped annotation. In many cases there is
another annotation e.g breakpoint to tell Emacs this. However, in some cases,
e.g after `finish' or `return', frame-begin is the first `stopping' annotation
that GDB issues before printing (out frame details).
So I propose the patch below. It means that the stopped annotation gets printed
twice but that doesn't matter to Emacs. It's not elegant but, hey, it works!
I think Emacs is the only application that is interested in level 3
annotations so could "-gnuemacs" be made an alias option for "-annotate=3"?
>From GDB's point of view this would discourage new applications form using
it. From Emacs point of view, it would legitimise changes that we would wish
to make.
