I would have liked to make it a tal object, then we'd catch most
things with our memleak detection. However, sqlite3 doesn't seem to
allow allocator overrides.

We use it on the secrets array for the moment, but it's also useful
for remote_shutdown_scriptpubkey, as used in the next patch.

This is necessary to grad the their_unilateral/to-us outputs since
they aren't being harvested by `onchaind`

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.

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.

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.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

Not the nicest code, but it allows us to store the bip32_max_index so
that we don't forget our addresses upon restart. We could have done
the same by retrieving the max index from our index, but then we'd
forget addresses that don't have an associated output. Conversion
to/from string is so that we can store arbitrary one off values in the
DB in the future, independent of type.
