lnchannel: implement freezing channels (for receiving) 
A bit weird, I know... :)
It allows for rebalancing our own channels! :P

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

invoices: deal with expiration of "0" mess 
Internally, we've been using an expiration of 0 to mean "never expires".
For LN invoices, BOLT-11 does not specify what an expiration of 0 means.
Other clients seem to treat it as "0 seconds" (i.e. already expired).
This means there is no way to create a BOLT-11 invoice that "never" expires.

For LN invoices,
- we now treat an expiration of 0, , as "0 seconds",
- when creating an invoice, if the user selected never, we will put 100 years as expiration
