  This adds field_unsigned and changes various places using field_fmt
with "%u" to use this instead.  This also replaces an existing
equivalent helper function in record-btrace.c.

	* cli-out.c (cli_ui_out::do_field_int): New method.
	* ui-out.c (ui_out::field_unsigned): New method.
	* symfile.c (generic_load): Use field_unsigned.
	(print_transfer_performance): Likewise.
	* record-btrace.c (ui_out_field_uint): Remove.

FWIW, offhand the naming looks a bit surprising to me.

Given the existence of "field_int", I'd expect "unsigned" to print an
unsigned (int), not a ULONGEST.

(I was initialize surprised it wasn't called field_uint, like the
ui_out_field_uint function that is removed by this patch, until I
realized this works with a ULONGEST.)

To output a ULONGEST, I'd expect the method to be called field_ulongest.

Is your plan to rename field_int to field_signed, perhaps?

Thanks,
Pedro Alves

I hadn't really considered it, but I can rename either one as you like.

I tend to think field_int should accept a LONGEST rather than an int.
So I suppose doing that & naming it field_signed would be a way to go.

What do think?

Right, I meant to ask whether the plan was to rename AND change
to LONGEST, for didn't for some reason.

That would work for me.

Agree. :-)

Ok, I sent a patch.
