Changeset 11463 with emu 785
part1 cleanup and fixes for gcc 8.2
[add] RossCrypt1 support via the Stream Relay*
[fix] Some PowerVu channels were missing audio when recording
[fix] Allow more PowerVu channels to be watched or recorded simultaneously**
*Refer to the wiki for information on how to configure the Stream Relay.
**This is done by not descrambling the subtitles on the PowerVu channels. The subtitles are always(?) un-encrypted, so this should not be a problem. If you come across a PowerVu channel with scrambled subtitles, please report.
