Since current behavior on release is to ban clients with too
high a height included in the request, it seems reasonably
justified to modify that behavior to instead return a successful
response that includes the chain height and top block hash.
Because of the missing `return` statement, the status is set to "OK" later on in the method when it shouldn't be.
Thank you to ADA Logics and the MAGIC Monero Fund for reporting this!
Behavior before: when start_height > chain tip, response fails
Behavior after: when req.high_height_ok is true && req.start_height
> chain tip, server rerturns a successful response that includes
chain height

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
Some downstream code (most notably PR https://github.com/UkoeHB/monero/pull/25) wants to use the src/serialization lib
for storing information persistently. When one builds classes/machines wishing to serialize containers, they must use
the `serializable_*` container classes. In this case, this makes the Seraphis library code unnecessarily tightly coupled
with the src/serialization code since one cannot swap out their type of storage format without major refactoring of class
field types. By serializing STL containers directly, we can abstract the serialization details away, making for much
cleaner design. Also small bonus side effect of this change is that STL containers with custom Comparators, Allocators,
and Hashers are serializable. `std::multimap` is added to the list of serializable containers.
Depends upon https://github.com/monero-project/monero/pull/9069.
Read more about k-anonymity [here](https://en.wikipedia.org/wiki/K-anonymity). We implement this feature in the monero daemon for transactions
by providing a "Txid Template", which is simply a txid with all but `num_matching_bits` bits zeroed out, and the number `num_matching_bits`. We add an operation to `BlockchainLMDB` called
`get_txids_loose` which takes a txid template and returns all txids in the database (chain and mempool) that satisfy that template. Thus, a client can
ask about a specific transaction from a daemon without revealing the exact transaction they are inquiring about. The client can control the statistical
chance that other TXIDs (besides the one in question) match the txid template sent to the daemon up to a power of 2. For example, if a client sets their `num_matching_bits`
to 5, then statistically any txid has a 1/(2^5) chance to match. With `num_matching_bits`=10, there is a 1/(2^10) chance, so on and so forth.
