This splits maybe_create_hsm_secret() in two parts (either encrypted
or in clear) for clarity, and adds an encryption detection in load_hsm().
There are actually three cases if an encryption key is passed:
- There is no hsm_secret => just create it and store the encrypted seed
- There is an encrypted hsm_secret => the provided key should be able to
decrypt the seed, if the wrong key is passed libsodium will nicely error
and hsmd will exit() to not throw a backtrace (using status_failed() as for
other errors) at the face of an user who mistyped its password.
- There is a non-encrypted hsm_secret => load the seed, delete the
hsm_secret, create the hsm_secret, store the encrypted seed.
Add a new startup option which will, if set, prompt the user for a
password to derive a key from. This key will later be used to encrypt
and/or decrypt `hsm_secret`.
This was made a noarg option even if it would have been preferable to
let the user the choice of how to specify the password. Since we have
to chose, better to not let the password in the commands history.
According to the doc (https://download.libsodium.org/doc):
"sodium_init() initializes the library and should be called before
any other function provided by Sodium. [...]
the function ensures that the system's random number generator has
been properly seeded.".
Command format: close id [unilateraltimeout] [destination]
Close the channel with peer {id}, forcing a unilateral
close after {unilateraltimeout} seconds if non-zero, and
the to-local output will be sent to {destination}. If
{destination} isn't specified, the default is the address
of lightningd.
Also change the pylightning:
update the `close` API to support `destination` parameter
`shutdown_scriptpubkey[REMOTE]` is original remote_shutdown_scriptpubkey;
`shutdown_scriptpubkey[LOCAL]` is the script used for "to-local" output when `close`. Add the default is generated form `final_key_idx`;
Store `shutdown_scriptpubkey[LOCAL]` into wallet;
Our policy is generally to omit fields which aren't sensible.
Also, @niftynei points out the spacing in for loops.

This triple join should be efficient to read, and to process. We have a
one-to-many (tx-to-annotations), followed by a
one-to-one (annotation-to-channel) join, so we are limited to annotations x
transactions results.
We have split the iteration over the txs and the output in different
functions, so pushing the annotation down, while keeping the transaction
addition atop. This showcases the need to not have the txid reference the
transactions.id in the DB: we annotate in a function that doesn't have the tx
index context, but only add the TX after we have finished extracting.
