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.

I started by trying to change the current infrastructure, but this is
really the only completely sync hook which makes sense; it needs to avoid
doing the db_transation, as well as waiting, and using a callback is just
overkill.
So with some regret, I open coded it.

I was tempted to create a new db_select_stmt wrapper type, but that means
a lot of boilerplate around binding, which expects to work with db_prepare
*and* db_select_prepare.
This lets us clearly differentiate between db queries (which don't need to
go to a plugin) and db changes (which do).

fixup printing methods in devtools/decodemsg such that TLV's can
now be printed as well. here's how you'd use it:
$ ./devtools/decodemsg --tlv opening_tlv 0120001E020202020202020202020202020202020202020202020202020202020202

This is what all of this has been working towards: ripping out the handwoven
transaction handling. By removing the custom parsing we can finally switch
over to using `wally_tx` as sole representation of transactions in
memory. The commit is a bit larger but it's mostly removing setters and old
references to the input and output fields.

Weaning `onchaind` off its use of the internal bitcoin_tx input and output
fields, since we're going to remove them soon, I promise.

These are handled internally in the `wally_tx` and do not conform to our usual
tallocated strings that can by inspected using `tal_bytelen`, and we don't
really want to litter our code with whitelisting comments for the
`amount_sat.satoshis` access, so these just do read-only on the fly conversions.

This is the second to last time I'm touching this file, just need to remove
the `tx->input` and `tx->output` swapping once they are removed.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
The `wally_tx_input`s do not keep track of their input value, which means we
need to track them ourselves if we try to sign these transactions at a later
point in time.

These are used when grinding the feerate and signing. These are just simple
facades that keep both wally and old style transactions in sync.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
During the migration to `libwally` we want to make absolutely sure that both
transactions are generated identical, and can eventually be switched over.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We are slowly migrating towards a wally-transactions only world, but to make
this reviewable we start building both old and new style transactions in
parallel. In a second pass we'll then start removing the old ones and use
libwally only.

1. Rename channel_funding_locked to channel_funding_depth in
channeld/channel_wire.csv.
2. Add minimum_depth in struct channel in common/initial_channel.h and
change corresponding init function: new_initial_channel().
3. Add confirmation_needed in struct peer in channeld/channeld.c.
4. Rename channel_tell_funding_locked to channel_tell_depth.
5. Call channel_tell_depth even if depth < minimum, and still call
lockin_complete in channel_tell_depth, iff depth > minimum_depth.
6. channeld ignore the channel_funding_depth unless its >
minimum_depth(except to update billboard, and set
peer->confirmation_needed = minimum_depth - depth).
In particular, `make unittest/bitcoin/test/run-secret_eq_consttime`
didn't set VALGRIND if it was set via config.vars, so runs for a *long*
time.
