Rings for outgoing transactions are stored within the scanning code since the last hardfork,
so this code is largely unneccessary now.

cd1c060 Daemon-specific proxy for the wallet-rpc. 1. Daemon-specific proxy is exclusive with global proxy (--proxy). 2. If you set global proxy (--proxy) you cannot set daemon-specific proxy. 3. If you don't set global proxy, you can set proxy (or not set) proxy for each daemon connection with the proxy field in jsonrpc to the wallet-rpc. (0xFFFC0000)
1. Daemon-specific proxy is exclusive with global proxy (--proxy).
2. If you set global proxy (--proxy) you cannot set daemon-specific proxy.
3. If you don't set global proxy, you can set proxy (or not set) proxy for
each daemon connection with the proxy field in jsonrpc to the wallet-rpc.
1. Use std::is_standard_layout and std::is_trivially_copyable instead of std::is_pod for KV byte-wise serialization, which fixes compile issue for Boost UUIDs
2. Removed reimplementation of std::hash for boost::uuids::uuid
3. Removed << operator overload for crypto::secret_key
4. Removed instances in code where private view key was dumped to the log in plaintext
Release version of #9450, containing C++14 modified assertions
- When background syncing, the wallet wipes the spend key
from memory and processes all new transactions. The wallet saves
all receives, spends, and "plausible" spends of receives the
wallet does not know key images for.
- When background sync disabled, the wallet processes all
background synced txs and then clears the background sync cache.
- Adding "plausible" spends to the background sync cache ensures
that the wallet does not need to query the daemon to see if any
received outputs were spent while background sync was enabled.
This would harm privacy especially for users of 3rd party daemons.
- To enable the feature in the CLI wallet, the user can set
background-sync to reuse-wallet-password or
custom-background-password and the wallet automatically syncs in
the background when the wallet locks, then processes all
background synced txs when the wallet is unlocked.
- The custom-background-password option enables the user to
open a distinct background wallet that only has a view key saved
and can be opened/closed/synced separately from the main wallet.
When the main wallet opens, it processes the background wallet's
cache.
- To enable the feature in the RPC wallet, there is a new
`/setup_background_sync` endpoint.
- HW, multsig and view-only wallets cannot background sync.

Added a relay rule that enforces the `unlock_time` field is equal to 0 for non-coinbase transactions.
UIs changed:
* Removed `locked_transfer` and `locked_sweep_all` commands from `monero-wallet-cli`
APIs changed:
* Removed `unlock_time` parameters from `wallet2` transfer methods
* Wallet RPC transfer endpoints send error codes when requested unlock time is not 0
* Removed `unlock_time` parameters from `construct_tx*` cryptonote core functions
@tobtoht: undo rebase changes tx.dsts -> tx_dsts
Looks like the logic from #8882 was accidentally removed in #8861
(regressing to the behavior noted in the #8882 description).
This commit brings that logic back.
To transfer ~5 XMR to an address such that your balance drops by exactly 5 XMR, provide a `subtractfeefrom` flag to the `transfer` command. For example:
transfer 76bDHojqFYiFCCYYtzTveJ8oFtmpNp3X1TgV2oKP7rHmZyFK1RvyE4r8vsJzf7SyNohMnbKT9wbcD3XUTgsZLX8LU5JBCfm 5 subtractfeefrom=all
If my walet balance was exactly 30 XMR before this transaction, it will be exactly 25 XMR afterwards and the destination address will receive slightly
less than 5 XMR. You can manually select which destinations fund the transaction fee and which ones do not by providing the destination index.
For example:
transfer 75sr8AAr... 3 74M7W4eg... 4 7AbWqDZ6... 5 subtractfeefrom=0,2
This will drop your balance by exactly 12 XMR including fees and will spread the fee cost proportionally (3:5 ratio) over destinations with addresses
`75sr8AAr...` and `7AbWqDZ6...`, respectively.

Since we are required to check for uniqueness of decoy picks within any given
ring, and since some decoy picks may fail due to unlock time or malformed EC points,
the wallet2 decoy selection code was building up a larger than needed *unique* set of
decoys for each ring according to a certain distribution *without replacement*. After
filtering out the outputs that it couldn't use, it chooses from the remaining decoys
uniformly random *without replacement*.
The problem with this is that the picks later in the picking process are not independent
from the picks earlier in the picking process, and the later picks do not follow the
intended decoy distribution as closely as the earlier picks. To understand this
intuitively, imagine that you have 1023 marbles. You label 512 marbles with the letter A,
label 256 with the letter B, so on and so forth, finally labelling one marble with the
letter J. You put them all into a bag, shake it well, and pick 8 marbles from the bag,
but everytime you pick a marble of a certain letter, you remove all the other marbles
from that bag with the same letter. That very first pick, the odds of picking a certain
marble are exactly how you would expect: you are twice as likely to pick A as you are B,
twice as likely to pick B as you are C, etc. However, on the second pick, the odds of
getting the first pick are 0%, and the chances for everything else is higher. As you go
down the line, your picked marbles will have letters that are increasingly more unlikely
to pick if you hadn't remove the other marbles. In other words, the distribution of the
later marbles will be more "skewed" in comparison to your original distribution of marbles.
In Monero's decoy selection, this same statistical effect applies. It is not as dramatic
since the distribution is not so steep, and we have more unique values to choose from,
but the effect *is* measureable. Because of the protocol rules, we cannot have duplicate
ring members, so unless that restriction is removed, we will never have perfectly
independent picking. However, since the earlier picks are less affected by this
statistical effect, the workaround that this commit offers is to store the order that
the outputs were picked and commit to this order after fetching output information over RPC.
Multisig keys per-transfer were being wiped, but not erased, which lead to a ginormous
quadratic bloat the more transfers and exports you performed with the wallet.
Ensures both transfers and sweeps use a fee that's calculated
from the tx's weight. Using different logic could theoretically
enable distinguishability between the two types of txs. We don't
want that.
The Monero GUI code was calling `Monero::wallet::setPassword()` on every open/close for some reason,
and the old `store_to()` code called `store_keys()` with `watch_only=false`, even for watch-only wallets.
This caused a bug where the watch-only keys file got saved with with the JSON field `watch_only` set to 0,
and after saving a watch-only wallet once, a user could never open it back up against because `load()` errored out.
This never got brought up before this because you would have to change the file location of the watch-only
wallet to see this bug, and I guess that didn't happen often, but calling the new `store_to()` function with the
new `force_rewrite` parameter set to `true` triggers key restoring and the bug appeared.

Resolves#8932 and:
2. Not storing cache when new path is different from old in `store_to()` and
3. Detecting same path when new path contains entire string of old path in `store_to()` and
4. Changing your password / decrypting your keys (in this method or others) and providing a bad original password and getting no error and
5. Changing your password and storing to a new file
