lnpeer/lnworker: refactor htlc_switch

Browse Source 
refactor `htlc_switch` to new architecture to make it more robust
against partial settlement of htlc sets and increase maintainability.
Htlcs are now processed in two steps, first the htlcs are collected into
sets from the channels, and potentially failed on their own already.
Then a second loop iterates over the htlc sets and finalizes only on
whole sets.
