Make the ATSC section parse handle both TVCT and CVCT as they are nearly the same struct (CVCT uses 2 reserved bits that are ignored in TVCT). This is changing the glib type and the struct name but TVCT wasn't released in a stable package yet so there should be no problem. Also includes some parsing fixes and changes short_name to be directly stored as utf8 rather than utf16 https://bugzilla.gnome.org/show_bug.cgi?id=730642
