We're about to add 'amount_msat' to getroute, but it's common to feed
'getroute' back into 'sendpay', so sendpay should allow it.
If both are specified, make sure they're the same!

Using param_tok is generally deprecated, as it doesn't give any sanity checking
for the JSON 'check' command. So make param_wtx usable directly, and
also make it have a struct amount_sat.

These create two fields, one old one which is purely numeric,
and a modern on with a suffix, eg "msatoshi" and "amount_msat".

The current param_sat accepts "any": rename and move that to invoice.c
where it's called. We rename it to param_msat_or_any and invoice.c
is our first (trivial) amount_msat user.

They're generally used pass-by-copy (unusual for C structs, but
convenient they're basically u64) and all possibly problematic
operations return WARN_UNUSED_RESULT bool to make you handle the
over/underflow cases.
The new #include in json.h means we bolt11.c sees the amount.h definition
of MSAT_PER_BTC, so delete its local version.

Final step for the `peer_connected` hook, we parse the result and act
accordingly. Currently we just close the underlying connection, but we
may want to clean up peers that did not end up with a channel.

The format is very similar to the one for `listpeers` except we only
list a single channel, and we list the actual netaddr that connected
instead of all known from gossip.

This used to be inline, but we want to pass channels to hooks as well,
so we just extract this into its own function.

This hook is used to let a plugin decide whether we should continue
with the connection normally, or whether we should be dropping the
connection. Possible use-cases include policy enforcement (dropping
connections based on previous interactions), draining a node by
allowing only peers with an active channel to reconnect, or
temporarily preventing a channel from making progress.

LND seems to do this occasionally, though fixed in new versions. Workaround
in the meantime.
I tested this by hacking our code to send it prematurely, and this worked.

We had occasional failures, because the fuzz could overwhelm the difference
in routes. Increasing the amount to 2,000,000 millisatoshis makes the
riskfactor 53msat (2000000 * 14 * 10 / 5259600) which is always greater
than the worst-case fuzz of 5% on the fee of 1002msat.

I got a spurious failure because the final node gave a CLTV error and
so it decided to use a different channel. It should probably handle
this corner case better, but meanwhile make the test robust.

We were not correctly allocating the `db->filename`, failing to copy the
null-terminator. This was causing and error when reopening the database after
the call to `fork()`.

This just takes the existing documentation, and generates a nice HTML
version we can point users to. The documentation is automatically
generated on every commit to `master` and will be deployed here:
https://lightning.readthedocs.io/

This is a preparatory step for the automatic documentation generation
that is going to use `sphinx-doc`. Each document should include a top
level header that matches the name and scope of the document and all
following headers should be of a lower level than the top-level
header.

We read a JSON message from the buffer, after converting it from raw bytes to
UTF-8, and returning the remainder of the byte array back to the
caller. However the return value of `raw_decode` refers to symbols in the
UTF-8 decoded string, not the raw bytes underlying byte-array, which means
that if we have multi-byte encoded UTF-8 symbols in the byte-array we end up
with a misaligned offset and will return part of the message as
remainder. This would then end up being interpreted as the result of the next
call.
This could not be exploited currently since we use a socket only for a single
JSON-RPC call and will close the connection afterwards, but since we want to
eventually recycle connections for multiple calls, this could have been very
dangerous.

This patch will properly set fee_per_satoshi to _unsigned_ integer,
as support for negative fees was removed from overall design.
This change does not break any tests, so I assume its
better this way.
also fixed grammar and consistency with other manpages.
The names are now the same as what json_connect() expects.
