Title: [cmyth] LiveTV chain never updated since e633f968d4e3c6a4f7b35cbb68eed84...

...3395628b1

Resolve stop show in critical circonstances: Switch on incomplete chain update.

- Add the new status (-1) for livetv_watch to allow chain update on program break,
but prevents switch during update.
- chain_add and chain_switch are locked to be threadsafe on mutual read/write.
