file, instead of relying on their (already existing) dependency on
$(LIGHTNINGD_HSM_CLIENT_OBJS), so we remove that.

This means some files get renamed, and I took the opportunity to clarify
our naming (the *d* is important!)
1. channeld/channel_wire.csv -> channeld/channeld_wire.csv
2. channeld/gen_channel_wire.h -> channeld/channeld_wiregen.h
3. enum channel_wire_type -> enum channeld_wire
4. WIRE_CHANNEL_FUNDING_DEPTH -> WIRE_CHANNELD_FUNDING_DEPTH.

The idea is that you regenerate the man pages in the same commit you
alter them: that's how we know whether to try regenerating them or not
(git doesn't store timestamps, so it can't really tell).
Travis will now check this, so force them all to sync to this commit.

You can't pay them anyway, and at least one person used 0 instead of "any".

We've never hit this, we do check them on insert, and it's slowing
down some operations unnecessarily.

We have sanity checks in there that it's a valid point. Simply store

This doesn't make any difference, since lightningd generally sends us
short commands (command responses are via the rpc loop, which is
already done), but it's harmless.

Changelog-Fixed: JSON-RPC: significant speedups for plugins which create large JSON replies (e.g. listpays on large nodes).
The jsmn parser is a beautiful piece of code. In particular, you can parse
part of a string, then continue where you left off.
We don't take advantage of this, however, meaning for large JSON objects
we parse them multiple times before finally having enough to complete.
Expose the parser state and tokens through the API, so the caller can pass
them in repeatedly. For the moment, every caller is allocates each time
(except the unit tests).

We're going to change the API on the more complete JSON parser, so
make and use a simple API for the easy cases.

Changelog-Fixed: libplugin: significant speedups for reading large JSON replies (e.g. calling listsendpays on large nodes, or listchannels / listnodes).
Most of what it does was actually a function of adding the input metadata
to the PSBT, so call that and simply copy out the tx input it creates.
