Rusty Russell 59e75f1b2c gossipd: reply to large listchannels in parts. 
This has two effects: most importantly, it avoids the problem where
lightningd creates a 800MB JSON blob in response to listchannels,
which causes OOM on the Raspberry Pi (our previous max allocation was
832MB).  This is because lightning-cli can start draining the JSON
while we're filling the buffer, so we end up with a max allocation of
68MB.

But despite being less efficient (multiple queries to gossipd), it
actually speeds things up due to the parallelism:

MCP with -O3 -flto before vs after:
-listchannels_sec:8.980000-9.330000(9.206+/-0.14)
+listchannels_sec:7.500000-7.830000(7.656+/-0.11)
