[PATCH] -stack-info-frame/-stack-list-frames

[Nick Roberts <nickrob at snap dot net dot nz>]

Here's a patch to add the frame address to the output of -stack-info-frame and
-stack-list-frames and async output when execution stops.  It also outputs the
source language for -stack-info-frame, these change making it more like "info
frame":

-exec-run
^running
(gdb) 
*stopped,reason="breakpoint-hit",disp="keep",bkptno="1",thread-id="1",frame={addr="0x08048539",frame_addr="0xbfa67af0",func="mysquare",args=[{name="x",value="8"}],file="myprog.c",fullname="/home/nickrob/myprog.c",line="67"}
(gdb) 
-stack-list-frames
^done,stack=[frame={level="0",addr="0x08048539",frame_addr="0xbfa67af0",func="mysquare",file="myprog.c",fullname="/home/nickrob/myprog.c",line="67"},frame={level="1",addr="0x08048753",frame_addr="0xbfa68ba0",func="main",file="myprog.c",fullname="/home/nickrob/myprog.c",line="176"}]
(gdb) 
-stack-info-frame
^done,frame={level="0",addr="0x08048539",frame_addr="0xbfa67af0",func="mysquare",file="myprog.c",fullname="/home/nickrob/myprog.c",line="67"},lang="c"
(gdb) 


I'll provide test and documentation patches when this change is approved in
principle.

	* mi/mi-cmd-stack.c (mi_cmd_stack_info_frame): Add "lang" field
	for source language of frame.

	* stack.c (print_frame_info): Add field for frame address.

	* Makefile.in (stack.o): Add dependency on language.h.
