* Add compatibility with the new shortchannelid syntax with x as separator
* Add an error message in case the parse failed, instead of receveing an unrelated error from the bitcoin-cli
WIRE_REQUIRED_CHANNEL_FEATURE_MISSING anticipates a glorious Wumbo future,
and is closer to correct (it's a PERM failure).

On master I get a crash and the following from valgrind, which
seems like a libwally bug. Upgrading made it go away.

Make --announce-addr with autotor: also
a meaningful use case.
The option --announce-addr=autotor: is more
intuitive than to use the --addr=autotor: option

Declare opt_add_addr at top of option.c
We we use opt_add_addr and opt_announce_addr vice versa.
To make compiler happy, we declare it at top.

Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

We now have a pointer to chainparams, that fails valgrind if we do anything
chain-specific before setting it.
Suggested-by: Rusty Russell <@rustyrussell>
We used to match specifically on `is_elements && coinbase`, but we can just
hand off responsibility to libwally and then make sure we handle it correctly.
The fundchannel plugin needs to know how to build a transaction, so we need to
tell it which chainparams to use. Also adds `chainparams` as a global, since
that seems to be the way to do things in plugins.
Turns out that if we have the init message contain both the chainparams as
well as a transaction that needs to be parsed we need to set the parser to
elements mode before we reach the transaction...
This is the main reason we started weaving the chainparams everywhere: being
able to compare the asset type with the fee paying asset tag, thus determining
the value of the asset correctly (we still treat any non-fee-paying assets as
having value 0).

This is required since liquid-regtest and liquidv1 have different asset tags
for L-BTC which is the fee-paying asset.

In elements we add an explicit fee output, if we don't consider it when
selecting coins, we end up underpaying the fees.

Since elements addresses look quite different from the bitcoin mainnet
addresses I just added a sample to the chainparams fixture. In addition I
extracted some of the fixed strings to reference chainparams instead.

We were checking against hardcoded hrp and prefixes. Now we parametrize via
the chainparams.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
Especially when we grind fees we may end up setting the fees several times, so
instead of always adding a new fee output look for an existing one and set its
value.

Elements requires us to have an explicit fee output instead of bitcoin's
implied fee. We add the fee output mostly after sorting the other outputs
since that matches the behavior in elements itself.

We are checking against chain-dependent constants, so let's make sure we are
using the ones for the correct chain.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We use to use the non-elements ones and then patch them manually. By using the
correct ones right from the start we have less work on our side.

Depending on the network we end up with different signature hash algorithms,
so we just collect that decision in one place.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
If we are handling an elements transaction the value is not stored in the
satoshi field, rather it is stored in the `value` field which is prefixed with
a version (0x01) and is counted in `asset` units.

The header is not a contiguous section of memory in elements, and it is of
variable length, so the simple trick of hashing in-memory data won't work
anymore. Some of the datafields would have been wrong on big-endian machines
anyway, so this is better anyway.
