If a tx is marked as failed (because it never shows up in the
daemon's pool), its key images get reset back to unspent so they
can be used in future txs.
If the tx re-enters the daemon's pool (e.g. it's removed from the
pool and then relayed back), then the wallet incorrectly maintains
that the tx's key images are unspent.
This change ensures the wallet re-marks the tx's key images as
spent if the tx re-appears in the node's pool.
A reorg can end up causing an output's position in the chain to
move. Since the wallet doesn't update the RingDB on reorg, it
may refer to the output's stale position in the chain.
This seems a reasonable solution rather than introducing complex
logic to update the stale ring member's value on rerog, since
RingDB can be deprecated with FCMP++.
- Make sure to mark identified spends in the pool as spends. The
wallet might not know these have been spent if it wasn't the wallet
that relayed the tx to the daemon, or the wallet was cleared via
rescan_bc.
- Make sure to add spends to m_unconfirmed_txs if not present.
- Make sure to process the entire pool again if refreshing for
the first time. The wallet fetches pool and blocks at the same
time. The wallet scans blocks first, then pool. If the wallet
identifies received outputs in the chain, then it may have spent
those received outputs in the pool. So we make sure to re-process
the entire pool again after scanning the chain for the first time.
- Multisig wallets that know about spent key images can now detect
spend txs in the pool. Update tests for that.
Fix four issues with wallet_keys_unlocker:
1. It won't decrypt if there are unlockers open simulataneously on multiple `wallet2` instances
2. It won't decrypt if the first unlocker was disabled (i.e. `locked=false`), even with a second non-disabled unlocker
3. If a destructor of an earlier unlocker is triggered before the destructor of a later unlocker, it will re-encrypt too early, while the second unlocker is still in scope
4. Calling the 3-parameter constructor with `locked=true` after an unlocker already exists will "double-encrypt" the spend key after its destructor since the local variable is `locked=false` and the field member is `locked=true`
Also, replace `wallet2::decrypt_account_for_multisig` with `wallet_keys_unlocker`.
Rings for outgoing transactions are stored within the scanning code since the last hardfork,
so this code is largely unneccessary now.

The commit kills support for deprecated ephemeral Boost messages: signed/unsigned transaction sets, pending transactions, reserve proofs, MMS messages, etc.
It does NOT kill support for loading very old wallets in Boost format, that should be supported indefinitely. These messages were deprecated 5 years ago. Since
then, we have had a hard fork to enable a new non-compatible transaction type (w/ view tags), and disable the old transaction type. This renders basically all
of the aforementioned messages before that HF useless, with the possible exception of reserve proofs.
This commit also cleans up dead inclusions of boost serialization headers.
This commit is part of upstreaming Carrot/FCMP++. Killing support for Boost messages now means less boilerplate Boost serialization review for Carrot/FCMP++.
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. Use `std::has_unique_object_representations` instead of `alignof(T) == 1` for epee byte spans and epee hex functions
3. Removed reimplementation of `std::hash` for `boost::uuids::uuid
4. Removed `<<` operator overload for `crypto::secret_key`
5. Removed instances in code where private view key was dumped to the log in plaintext
