If we have an array of varlen structures (which require a ctx arg), we
should make that arg the array itself (which was tal_arr()), not the
root context.

This simplifies lifetime assumptions. Currently all callers keep the
original around, but everything broke when I changed that in the next
patch.

They were not universally used, and most are trivial accessors anyway.
The exception is getting the channel reserve: we have to multiply by 1000
as well as flip direction, so keep that one.
The BOLT quotes move to `struct channel_config`.

We keep a chain_hash in struct daemon, becayse otherwise we end up with
`&peer->daemon->rstate->chainparams->genesis_blockhash` which is a bit
ridiculous.

We only take the pubkey and ignore all other fields, so we might as well
save the cycles used computing the hash for something else.

We probably also want to call secp_randomise/wally_secp_randomize here
too, and since these calls all call setup_tmpctx, it probably makes
sense to have a helper function to do all that. Until thats done, I
modified the tests so grepping will show the places where the sequence
of calls is repeated.

This avoids some very ugly switch() statements which mixed the two,
but we also take the chance to rename 'towire_gossip_' to
'towire_gossipd_' for those inter-daemon messages; they're messages to
gossipd, not gossip messages.

We had at least one bug caused by it not returning true when it had
queued something. Instead, just re-check thq queue after it's called.

We shouldn't insist on an exact reponse match: they can batch it and send
a whole batch, as long as it overlaps what we ask.
We also change to a bitmap to save some memory.
This isn't note in the CHANGELOG since we don't actually send gossip
range queries except for testing.

Messages from a peer may be invalid in many ways: we send an error
packet in that case. Rather than internally calling peer_error,
however, we make it explicit by having the handle_ functions return
NULL or an error packet.
Messages from the daemon itself should not be invalid: we log an error
and close the fd to them if it is. Previously we logged an error but
didn't kill them.

We now keep multiple commands for a json_connection, and an array of
json_streams.
When a command wants to write something, we allocate a new json_stream
at the end of the array.
We always output from the first available json_stream; once that
command has finished, we free that and move to the next. Once all are
done, we wake the reader.
This means we won't read a new command if output is still pending, but
as most commands don't start writing until they're ready to write
everything, we still get command parallelism.
In particular, you can now 'waitinvoice' and 'delinvoice' and it will
work even though the 'waitinvoice' blocks.

json_stream_success / json_stream_fail belong in jsonrpc.c, and the
json_tok helpers for special types belong in json.x
json_add_object() isn't used, remove it rather than moving it.

We promote 'struct json_stream' to contain the membuf; we only attach
the json_stream to the command when we actually call
json_stream_success / json_stream_fail.
This means we are closer to 'struct json_stream' being an independent
layer; the tests are already modified to use it directly to create
JSON.
This is also the first step toward re-enabling non-serial command
execution.

This doesn't make a performance difference, but even better, it
simplifies the code.
We hacked test_multirpc to send 200x as many commands, and timed the
pytest over 20 runs:
Before:
=================== 1 passed, 136 deselected in 8.550000-9.400000(9.0045+/-0.2) seconds ===================
After:
=================== 1 passed, 136 deselected in 8.540000-9.370000(8.97286+/-0.16) seconds ===================

We need to keep the remaining buffer, and we need to try to parse it
before we read the next. I first tried keeping it in the object, but
its lifetime is that of the *socket*, which we actually reopen for
every command.

This was hanging sometimes in travis, but actually checking the result
of the commands makes it *always* hang. We remove the waitinvoice
which will not return.
ZmnSCPxj points out that this behavior, introduced in
ce0bd7abd3, is a regression: it would be
nice to be able to cancel a waitinvoice. But that fix is more complex,
and will have to be another PR.
This test will now hang, but it's OK: we're about to fix it!
