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).
Now that the default newaddr type is bech32, this step seems to be tripping
people up.

This gives the network options a chance to load from arguments before usage
exits, so that the proper defaults are shown.
This didn't work:
lightningd --mainnet --help
before it showed testnet defaults, now it shows mainnet defaults.

This adds one line with the onion and the channel_update we extract from
it. This in turn allows us to check that the channel_update in the onion is not
type prefixed, and that we patch it correctly before passing it to gossipd.
As was pointed out by @robtex we have underspecified the format of the nested
`channel_update` in the onionreply: lnd and eclair inserted the raw
channel_update without the type prefix, while we went for the full wire format,
including the type prefix. While we agreed that with the type it is more
flexible, and consistent, we decided to adapt to the majority and at least be
compatibly broken.
This commit takes care of being able to interpret either format correctly. It's
not perfect since signatures can happen to start with 0x0102 (the channel_update
type) but that'll happen only once ever 65k failures.
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.

The visible changes are:
1. tal_len() is renamed to tal_bytelen() for clarity.
2. tal allocations *always* know their length.
3. tal/str routines always set the length to strlen() + 1.

In several places we use low-level tal functions because we want the
label to be something other than the default. ccan/tal is adding
tal_*_label so replace them and shim it for now.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

This seems like a premature optimization: it tried to cut down the number of
allocations by reusing the same `struct invoice_details` while iterating through
a number of results. But this sidesteps the checks by `valgrind` and we'd miss a
missing field that was set by the previous iteration.

`wallet_stmt2payment` always expects the same fields in the same order, so we
should make sure that we always fetch them in that order and all of them.
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.
This commit adds a new option, exempting tiny fees (up to 5 satoshis by default)
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.
