[PATCH setup 0/2] Improve behavior after download error

[Ken Brown <kbrown@cornell.edu>]

This is a followup to
https://sourceware.org/ml/cygwin-apps/2017-11/msg00003.html.  The
focus of that thread was a crash that occurs on the topic/libsolv
branch.  Here I'm more interested in a UI issue.  Namely, I don't
think it's reasonable that setup goes back to the site page if the
user clicks Yes in response to "Download Incomplete. Try again?".
This is not what the message says will happen, and I'm not convinced
that it even works right if the user changes mirrors after being sent
to the site page.

The first patch in this series instead puts the relevant code in a
retry loop.  This should require indentation of a large amount of
code.  To keep the patch readable, I've saved the indentation for a
separate patch.
