These weren't checked by CI yet, and they are really short so I just added
them to the check-python target.

This indicates that the method or hook will accepts a request
parameter, and will use that to return the result or raise an
exception instead of returning the return value. This allows the hook
or method to stash the incomplete request or pass it around, without
blocking the JSON-RPC interface.

This isn't a problem for now since we don't support multithreading,
and only allow synchronous calls, but eventually this'll become
important.

We well need this in the next commit to be able to return from an
asynchronous call. We also guard stdout access with a reentrant lock
since we are no longer guaranteed that all communication happens on
the same thread.

Sending around unnamed tuples is bound to cause some issues sooner or
later, so we just create a quick class that holds all the information
about a plugin method.

An uncommitted channel should not keep the peer in the db, since the
uncommitted channel isn't in the db itself.

We need to do it in various places, but we shouldn't do it lightly:
the primitives are there to help us get overflow handling correct.

Basically we tell it that every field ending in '_msat' is a struct
amount_msat, and 'satoshis' is an amount_sat. The exceptions are
channel_update's fee_base_msat which is a u32, and
final_incorrect_htlc_amount's incoming_htlc_amt which is also a
'struct amount_msat'.

As a side-effect of using amount_msat in gossipd/routing.c, we explicitly
handle overflows and don't need to pre-prune ridiculous-fee channels.

We used to just throw htlcs into the channel with a flag to tell it to
ignore overflow. Instead, we can insert them in order (which is the same as
id order) which always must be valid.
This helps when we turn the balance into a struct amount_msat which will get
upset with overflows.

This is particularly interesting because we handle overflow during route
calculation now; this could happen in theory once we wumbo.
It fixes a thinko when we print out routehints, too: we want to print
them out literally, not print out the effect they have on fees (which
is in the route, which we also print).
This ABI change doesn't need a CHANGELOG, since paystatus is new since
release.

Little point having users handle the postfixes manually, this
translates them, and also allows Millisatoshi to be used wherever an
'int' would be previously.
There are also helpers to create the formatting in a way c-lightning's
JSONRPC will accept.
All standard arithmetic operations with integers work.

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.
