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.
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.

The manpage did not specify the name of the named parameter (addresstype).
It does now.
Fixed manpage grammar errors.

I went to the Nakamoto dinner last week and told some guys they
could get involved by improving our test coverage. So I updated
the docs for newbs like me. (I only recently discovered `PYTEST_PAR`).

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!

New codes: FUND_MAX_EXCEEDED, FUND_CANNOT_AFFORD, FUND_DUST_LIMIT_UNMET.
The error message "Cannot afford fee" was not exactly correct because
it would also occur if the amount requested could not be afforded. So
I changed it to the more generic "Cannot afford transaction".
Other things:
* Fixed off-by-one satoshi in fundchannel manpage.
* Changed 'arror' to 'error' because we are not pirates.
Proposed fix for issue #1231 - FreeBSD (tcsh) build problem due
to HOST environment variable.
The variable is used for cross-compilation. The process may be
improved even further in the future. So far this hot fix.
Currently the Tor port for autotor is always 9735; the --port option
is deprecated, though we could append an optional '[@portnum]' to
'autotor' if people want it.

This is a rebased and combined patch for Tor support. It is extensively
reworked in the following patches, but the basis remains Saibato's work,
so it seemed fairest to begin with this.
Minor changes:
1. Use --announce-addr instead of --tor-external.
2. I also reverted some whitespace and unrelated changes from the patch.
3. Removed unnecessary ';' after } in functions.

These are basic instructions that lead to the build process completing without error (after a known error occurs and is rectified). For now, the final results are untested.
In particular: label must be a string, and description cannot use any
the JSON unicode escapes, which should be unnecessary with UTF-8
anyway.

* build: update INSTALL.md to include Fedora #1028

This time the rendered output is slightly different, but mostly
because long preformatted lines are wrapped and contain an extra
continuation backslash now.
These error codes will cause `pay` to retry, so `pay` will never
actually report those error codes.
Those error codes will only get reported at the `sendpay` level.
delinvoice was orginally documented to only allow deletion of unpaid
invoices, but there might be reasons to delete paid ones or unexpired ones.
But we have to avoid the race where someone pays as it's deleted: the
easiest way is to have the caller tell us the status, and fail if
it's wrong.

Paid invoices need to know how much was actually paid: both for the case
where no 'msatoshi' amount was specified, and for the normal case, where
clients are permitted to overpay in order to help them disguise their
payments.
While we migrate the db, we leave this field as 0 for old paid
invoices. This is unhelpful for accounting, but at least clearly
indicates what happened if we find this in the wild.

'rhash' is the old terminology, but 'payment_preimage' and
'payment_hash' were decided on for the BOLTs, so we should fix that here.
We still use rhash internally, but that's much easier to fix.

1) Note incorrect label in txs in Fig1 of LN paper.
2) "an atomic-swap an on-chain.." -> "an atomic-swap *to* an on-chain"
3) "By using a dual anchor and escape transactions" -> "By using a rebalanced single anchor"
4) References to appendices fixed.
5) Move escape transaction scripts out to escape appendix.
6) Fix URL in bibliography (missing comma).

As the signature doesn't cover the input itself, you could replace the
secret key from the escape transaction with 0, and it will use the "A and B"
branch of the output.
(This also fixes a bug in the anchor output where the OP_IF consumed the
secret).
