This allows it to be used to fetch the current staking requirement by
just asking for a height of 0, while currently you'd first have to fetch
the height and then pass that in.
The RPC wallet `fill_response` calls were still passing `req.blink` to
blink a tx, but that is supposed to be deprecated in favour of passing
(just) `priority=5`. Fixed it to blink based on the priority instead.
construct_tx_and_get_tx_key modifies the splitted_dsts vector which can
change the value of the reference I took to the dts entry. This change
undoes that and restores the behaviour to make a copy of the dst.
- get_settings SQL was using get_owner_by_id query
- Settings row was queried sometimes by ID vs rowid
- Initialising DB against the checkpoint instead of the latest block
- Removing other LNS type references means needing to update the lns commands in CLI wallet
- wallet2 passing the value encoded in ascii into tx extra
- constexpr functions in common/loki.h for inlining
- move hex functions out from common/loki.h to common/hex.h
- use and apply prev_txid on LNS TX's to all LNS types (for updating in the future)
- add lns burn type, for custom burn amounts
- accept and validate lokinet addresses via base32z
- return lokinet addresses in RPC LNS calls via base32z
- updated Messenger references to Session
- update documentation to note that only Session LNS entries are allowed currently
- remove raw c-string interface from LNS db
- update multi-SQL queries into single SQL queries
- remove tx estimation backlog in anticipation for 2 priorities only, blink + unimportant
We allow arbitrary reorganizations for the LNS DB by storing the
previous TXID that purchased the LNS record. When reorganizing, we
iterate back through the blockchain looking for the first LNS entry that
is before the reorganize height and revert the LNS entry to that record.
We want to allow people to buy LNS entries on behalf of other users. If
this is the case we don't need signatures to verify that the purchaser
knows the secret key. What we actually want in this scenario is that,
there's a LNS entry, and people can voluntarily pay to renew/buy that.
