This allows you to prepare a tx, then release or discard it later.

Value randomization is not implemented since `pay` was made into a plugin.
Nobody has been asking for it, so do not implement it and just remove
from documentation.
Shadow routes is implemented, and not describe, so describe it now.
This was deeply surprising to me; there's a difference between a value not being
specified, and it being specified as "".

If we have plugins configured in the default config location, then
`check-manpages` may fail due to plugin cli options being added to the
`--help` output.
This also allows plugins to do "hold invoices" a-la LND, useful for
just-in-time inventory handling.
We're careful to handle the invoice getting paid behind our backs, and
the incoming HTLC going away.
Once @cdecker's sphinx rework is in, we can also hand the raw payload
to the invoice_payment_hook, for special effects.

In theory we could allow a db_write-using plugin to have other
hooks/commands by embargoing their other responses until the exclusive
period is over. That would be nice for a 'dbmirrorinfo' command, for
example.
The other option would be to *always* go exclusive on a db_write-using
plugin, so responses can never get intermingled.

Case 5 in the Tor documentation currently states that if you use `--bind-addr=autotor:127.0.0.1:9051`, you can get your onion address by running `lightning-cli getinfo`. I have not found that to be the case; with that flag no onion address will be generated.
On the other hand, if `--addr=autotor:127.0.0.1:9051` is used instead, an onion address is generated and `lightning-cli getinfo` behaves as the docs say.
We document how to bind to them, just not how to connect to them.

This is the same deprecation, but one level up. For the moment, we
still support invoices with a `h` field (where description will be
necessary) but that will be removed once this option is removed.
Note that I just changed pylightning without backwards compatibility,
since the field was unlikely to be used, but we could do something
more complex here?
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This field was used by `pay` to hold the bolt11 description if the bolt11
string used `h` to hash the description (which nobody ever did). If the
`h` field wasn't present, it could contain anything, as it wasn't checked.
It's really useful to have a label for payments (eg. '1 Cuban'), but adding
yet-another option would be painful, so we simply rename 'description'
to 'label' except inside the db.
This means we need to do some tricky parameter parsing to handle array
and keyword JSON arguments, but only until we remove the old name.

Up until now, riskfactor was useless due to implementation bugs, and
also the default setting is wrong (too low to have an effect on
reasonable payment scenarios).
Let's simplify the definition (by assuming that P(failure) of a node
is 1), to make it a simple percentage. I examined the current network
fees to see what would work, and under this definition, a default of
10 seems reasonable (equivalent to 1000 under the old definition).
It is *this* change which finally fixes our test case! The riskfactor
is now 40msat (1500000 * 14 * 10 / 5259600 = 39.9), comparable with
worst-case fuzz is 50msat (1001 * 0.05 = 50).

- result fundchannel command now depends on successful or failed broadcast of the funding tx
- failure returns error code FUNDING_BROADCAST_FAIL
- don't fail the channel when broadcast failed, but keep in CHANNELD_AWAITING_LOCKIN
- after fixing the initial broadcast failure, the user could manually rebroadcast the tx and
keep the channel
openingd/opening_funder_finished:
- broadcast_tx callback function now handles both success and failure
jsonrpc: added error code FUNDING_BROADCAST_FAIL
manpage: added error code returned by fundchannel command
This makes the user more aware of broadcast failure, so it hopefully doesn't
try to broadcast new tx's that depend on its change_outputs. Some users have reported (see
issue #2171) a whole sequence of fundings failing, because each funding was using the change
output of the previous one, which would not confirm.
My manpage viewer did not know what to do with curly braces,
so I switched them to quotes and it works fine.

Right now, the `config` file is read *after* the configuration working directory is moved to in the software. However one configuration option `lightning-dir` settable in the `config` file sets this working directory. As the directory is already opened (which defaults to `$HOME/.lightning`) before the configuration is read, the configured directory will not be used.
This patch parses the configuration file before opening the working directory, fixing this bug.

Also:
- the lines of code that contain more than one elements are no more inline.
This should improve visualization in small screens (no auto line wrapping).
- Found a "solution" for the references: people looking at markdown presentation
will see one only reference to the Tor project.
In the text source all the "references" are shown and also serve in markdown as
hypertext links.
Feel free to improve.
- difference between --bind-addr=autotor and --addr=autotor
- typos corrected (non-persistent and Tor)
- "references" dropped
- table improved
- Outgoing case explained where is useful
The actual structure suffers of many repetitions. I could work on
a compact structure based on a "decision tree modular" approach if that
may seem useful.
Adapted for the markdown format.
Also developed in the preparation parts and each case of use has been detailed.
A doubt in the non persistent address remain:
In the original document
> --announce-addr=autotor:<torservice_ip:port> : try to generate an temp V2 onion addr.
this doesn't seem to work for me (several errors are produced at start up).
instead the `--addr=autotor:127.0.0.1:9051`seems to work well (at least for version 0.6).
The easiest way to do this is to play with the 'wallet_tx' semantics
and have 'amount' have meaning even when 'all_funds' is set.
Note that we change the string 'Cannot afford funding transaction' to
'Cannot afford transaction' as this code is also used for withdrawls.

Several users have noticed that they cannot pay satoshis.place or similar places
that have tiny payment amounts if they are not directly connected. This is due
to the forwarding fee dominating the transferred amount.

from having to pass the maxfeepercent flag. While we could have told users to
tweak maxfeepercent I think it is usefull to have a default exemption.

structeq() is too dangerous: if a structure has padding, it can fail
silently.
The new ccan/structeq instead provides a macro to define foo_eq(),
which does the right thing in case of padding (which none of our
structures currently have anyway).
Upgrade ccan, and use it everywhere. Except run-peer-wire.c, which
is only testing code and can use raw memcmp(): valgrind will tell us
if padding exists.
Interestingly, we still declared short_channel_id_eq, even though
we didn't define it any more!
