This is based on ds/maintenance-part-3.

After sitting with the background maintenance as it has been cooking, I
wanted to come back around and implement the background maintenance for
Windows. However, I noticed that there were some things bothering me with
background maintenance on my macOS machine. These are detailed in PATCH 3,
but the tl;dr is that 'cron' is not recommended by Apple and instead
'launchd' satisfies our needs.

This series implements the background scheduling so git maintenance
(start|stop) works on those platforms. I've been operating with these
schedules for a while now without the problems described in the patches.

There is a particularly annoying case about console windows popping up on
Windows, but PATCH 4 describes a plan to get around that.

Update in V7
============

 * I had included an "encoding" string in the XML file for schtasks based on
   an example using UTF-8. The cross-platform tests then complained (in
   xmllint) because they wrote in ASCII instead. However, actually testing
   the situation on Windows (see [1]) against the real schtasks finds that
   it doesn't like that encoding string. I removed it entirely, and
   everything seems happier.

 * I squashed Eric's two commits making the tests better. He remains a
   co-author and I kept his Helped-by. I had to rearrange the commit message
   a bit to point out the care he took for the cross-platform tests without
   referring to the test doing the wrong thing.
