[PATCH] Simplify the ui-out progress API

[Tom Tromey <tromey@adacore.com>]

I noticed that 'progress' is a method on ui-out, but it seems to me
that it would be better if the only API were via the progress_meter
class.  This patch makes this change, changing progress to be a method
on the meter itself.
