Update to 1.8.2.3
    
    A security release is coming next and it's a reasonable time to pull in
    the few upstream bug fixes since 1.8.2.1.
    
    Also update the source URL's to use https.  The htmldocs and manpages
    packages are not available on kernel.org and there are no detached
    signatures for them, but we can get decent protection for the downloads
    by using https.
