A program's stderr may have been redirected by the operator. We want to
query the size of stdout, even though it is buffered, so add fflush() to
handle that.

Programs that may be called in the background or with the stdin/stdout
redirected are not proper TTYs and we should not try to perform any
tricks on them. This patch checks isatty() and returns standard term
sizes as a fallback.

This patch adds a very simple progress bar I wrote once. It's revision
f98c5d0 from https://github.com/troglobit/toolbox
Also included in this patch is conio.h, a neat little set of macros for
manipulating your terminal using ANSI escape seequences.
