Move progressmeter formatting out of signal handler.

This is moves the formatting entirely out of signal handler context and
into code called by the atomicio callback.

It changes atomicio call the callback on EINTR and EAGAIN so that
SIGALRM will interrupt the read or write and the callback will update
the progressmeter at the appropriate time.
