[mythtv] MythTV 'master' branch needs a new library

[David Hampton]

Hi everyone,

I just pushed a new commit that replaces the old OSADB and minizip code
used by MythTV with libzip. The OSADB code hasn't been updated since
2008, and most distributions are still using minizip 1.x when version
3.x has been out for years. All the os/distributions that MythTV
supports have a fairly current version of libzip.

If you update 'master' and pick up commit be856e4cfa, you will need to
install libzip-devel or libzip-dev, depending on your system.

David
