Add stdio support to gdbreplay

I've been using gdbreplay to help debug an intermittent failure, and I
wanted it to be a little simpler to use.  This patch adds support for
"-" as the "address" argument.  With this patch you can do:

    (gdb) target remote | gdbreplay logfile -

... and not have to start gdbreplay in a separate shell.
