Rusty Russell 4fb472b7a7 db: we must always be in a transaction, remove nested, call fatal()
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.
