[RFC] GDB/MI -symbol-* functions

Hi again!
I've updated the mi-cmd-symbol patch and tried to incorporate the
given comments.
However, I was wondering whether making
-symbol-info-address, -symbol-locate and -symbol-info-symbol one
function would be useful? In the current patch they're just all three
using the same C function.
-symbol-type seems to already be somewhat implemented in
mi/mi-cmd-var.c - would implementing this function be desired?
Btw, are there currently any programs using the GDB/MI interface
(except for cgdb)?
Comments please ! :-)
