The filter is being populated while initializing the daemon and by
adding new keys as they are being generated. The filter is then used
in connect_block to identify transactions of interest.

We weren't incrementing the `col` for the `local_shutdown_idx` field,
which meant that all following fields were incorrect. I removed the
`col` computation and opted for absolute indices instead, since they
are way less brittle. Just remember to add new fields to the query at
the end so we don't have to shift too often :-)

The wire protocol uses this, in the assumption that we'll never see feerates
in excess of 4294967 satoshi per kiloweight.
So let's use that consistently internally as well.

support any form of paging.

We save location where transaction was started, in case we try to nest.
There's now no error case; db_exec_mayfail() is the only one.
This means the tests need to override fatal() if they want to intercept
these errors.

We're going to be always in a transaction soon.
Note the rollback we used to do was an optimization: the utxo destructors
would already clean up the new UTXOs in the database.

we should never be doing two startups at once, but why take chances? Plus,
we can then assert that all db calls are in transactions.

This is the only case where we actually rely on the db to ensure we don't
do something twice: don't error out if it fails.

Otherwise we find ourselves outside a commitment. This is a bandaid
until we remove nested commitments again at the end of this series.

Nesting is provided by only actually performing the outermost
transaction and simulating the nested ones. This still allows us to
ensure on lower levels that we are in the context of a transaction
without having to resort to keeping explicitly track of it in the
calling code.

In addition we also set some of the test values to a pattern instead
of just `memset`ting it to 0, which may hide some crossed lines.

We use these quite often and it is cumbersome having to do these
simple conversions inline, so just expose pseudo-sqlite3 methods to
bind and extract from/to a stmt.

Technically it's the caller that'll own the statement, but it is nice
to have db_exec_prepared dispose of it.

"near \"AND\": syntax error"
This was caught by the "always keep errors for db_commit_transaction".

We'd like to not keep them in memory and retrieve them on-demand when
`onchaind` is launched. This uses the `channel_htlcs` table as backing
but only fetches the minimal necessary information.

This makes executing a query/command a two step process, but allows us
to use the native binding and avoid having to build queries as SQL
strings. Two major advantages are that we are no longer vulnerable to
SQL injections and that we do not have to hex-encode binary fields
like private keys, hashes, and routing onions, halving the storage
requirements for those.

This was causing me some trouble by making it look like the last query
failed, when it really was an old one. No need to drag failures around
for longer than needed.

This is a necessary evil since at the time we load `struct htlc_out`
associated with a channel we might not have loaded the `struct
htlc_in` that it depends on, so we defer the rewiring until we have
loaded all HTLCs for all channels. At that point rewiring MUST work,
otherwise we report a failure.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
While loading HTLCs from the database we might not yet have all the
incoming HTLCs loaded when loading a dependent htlc_out. So we defer
the wiring of the HTLCs until we are sure we have them loaded.
This is also the first step towards keeping that association only in
the database, since otherwise we cannot selectively load channels from
DB.
