lnmsg.decode_msg: dict values for numbers are int, instead of BE bytes 
Will be useful for TLVs where it makes sense to do the conversion in lnmsg,
as it might be more complicated than just int.from_bytes().

lnworker: fix type error re pending_payments, and impl malformed htlcs 
In old code, in lnpeer.htlc_switch(), "error" in lnworker.pending_payments
had incorrect type.

TODO: we need tests for payment failures...

8f3fcdd1a8 Fix detection of payments. 
1. In lnhtlc, sent_in_ctn and failed_in_ctn need to look at the
remote ctx, and they need to be called when we receive a revocation,
not when we send one.

2. In lnchannel, we use 3 lnworker callbacks:
   - payment sent/payment failed (called when we receive a revocation)
   - payment received (called when we send a revocation)

3. Make revoke_current_commitment return a single value.
The second value was only used in tests, there is no need
to bloat the code with that
