If a structure foo has a optional fields opt1 and opt2, this creates
towire_foo, towire_foo_opt1 and towire_foo_opt2 (since opt2 implies opt1),
similarly for fromwire_*.
This requires the callers to be updated to call the correct routines (eg.
try fromwire_foo_opt2, then fromwire_foo_opt1, then finally fromwire_foo),
but this is a minimal change to the generation code.

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.

This is a subset of a "bitcoind: wrap callbacks in transaction." from
the everything-in-transaction branch, but we need the ld pointer now.

ie. non-printable, quotes or escapes. We allow these outside tokens
(we expect tabs and \n for example).
This is a big hammer, but if someone really wants we can add support
later.

Don't try to escape them. It's whack-a-mole and they shouldn't do it anyway.

And nail "make check-source" to that specific version (which is a commit id,
not a branch name, so needs a different syntax for git).

Google lead me to a discussion about litecint, it suggested they would use
'ltc' and I don't really care.
