[PATCH 17/36] mi/mi-cmd-stack.c|frame filters: print_values <-> ext_lang_frame_args

The enums are value compatible by design, but building in C++ mode trips
on them, like:

...
gdb/mi/mi-cmd-stack.c:363:34: error: cannot convert ‘print_values’ to ‘ext_lang_frame_args’ for argument ‘3’ to ‘ext_lang_bt_status apply_ext_lang_frame_filter(frame_info*, int, ext_lang_frame_args, ui_out*, int, int)’
...

Fix this by adding a helper function.

gdb/ChangeLog:
2015-02-09 Pedro Alves <palves@redhat.com>

* mi/mi-cmd-stack.c (mi_apply_ext_lang_frame_filter): New
function.
(mi_cmd_stack_list_locals, mi_cmd_stack_list_args)
(mi_cmd_stack_list_variables): Use it.
