We often want a pointer which will turn to NULL if the pointed-to thing is
freed. This is possible with tal objects, so create it.

This is the modified-time of the file. We have to store it internally
since we overwrite the gossip file with compaction on startup.
This means the "are we behind on gossip?" heuristic is no longer inside
gossip_store.c, which is cleaner.

It sometimes fail with a bad_gossip error because the sending node
might not have found out about the channel when it gets a
channel_update. Make sure the whole network knows everything before
we start.

We completely rework test_node_reannounce: it's assumes we always ask for
all gossip and that assumption will be broken in future patches too.

I have seen some strange flakiness (under VALGRIND), which I have
traced down to dev-disconnect "+" not working as expected. In
particular, the message is not sent out before closing the fd.
This seems to fix it on Linux, though it's so intermittant that it's hard
to be completely sure.

This patch adds a channel_id parameter to allow for specifying
channels that are lacking a short_channel_id.
Useful in the case where a peer has 1) multiple channels (ONCHAIN etc)
and 2) a channel where the funding transaction hasn't been
broadcast/mined.
this is unnecessary, and actually severely limits the functionality
of `wally_tx_add_input`, which will expand the allocated input
length if there's not enough room for the additional input
```external/libwally-core/src/transaction.c
if (tx->num_inputs >= tx->inputs_allocation_len) {
/* Expand the inputs array */
struct wally_tx_input *p;
p = realloc_array(tx->inputs, tx->inputs_allocation_len,
tx->num_inputs + 1, sizeof(*tx->inputs));
...
tx->inputs = p;
tx->inputs_allocation_len += 1;
```
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;
