* mi-cmd-var.c: Change all remaining occurrences of ui_out_tuple_begin
to make_cleanup_ui_out_tuple_begin_end. Change all remaining
occurrences of ui_out_list_begin to make_cleanup_ui_out_list_begin_end. Use do_cleanups instead of ui_out_list_end or ui_out_tuple_end. This
is a fix for PR gdb/680.
* mi-cmd-stack.c: Ditto.
* mi-main.c: Ditto.
* mi-cmd-var.c (mi_cmd_var_update): Fix for PR gdb/672. For m2,
output list begin and end for "changelist" rather than tuple begin/end.
(varobj_update_one): For m2, add tuple begin and end for varobj
update output.
Add support for a variable object that tries to evaluate itself in
the currently selected frame, rather than in a fixed frame.
* wrapper.c,h (gdb_parse_exp_1): Added a wrapper for
gdb_parse_exp_1.
* varobj.h: Added USE_CURRENT_FRAME to varobj_type & changed def'n
of varobj_create.
* varobj.c (varobj_list): Return type indicates whether the
variable's type has changed (for current frame variables).
(varobj_update): Handle the case where the variable's type has
changed.
(delete_variable_1): Allow for deletion of variables that have not
been installed yet.
(new_root_variable): Initialize use_selected_frame variable.
(value_of_root): This is where most of the work to handle "current
frame" variables was added. Most of the complexity involves
handling the case where the type of the variable has changed.
(varobj_create): Add a "type" argument, to tell if the
variable is one of these "current frame" variables. Also protect
call to parse_exp_1 from long jumping.
* mi-var-block.exp: The error report from varobj_create changed
since I am now trapping parse_exp_1 errors. Change the tests to
match the new error message.
* mi-var-child.exp: Ditto.
* mi-var-cmd.exp: Ditto.
* lib/gdb.exp: Fix the gdbtk_start routine to correctly find all
the library directories.
* gdbtk-varobj.c (variable_create): Pass the correct
"how_specified" flag to the varobj_create routine.
