1ed5681407 rpc: add missing scantxoutset examples (Sebastian Falbesoner)
Pull request description:
The scantxoutset RPC and its help text was at last improved in #16285, but it's still missing examples (see https://github.com/bitcoin/bitcoin/pull/16285#issuecomment-529313781).
~Note that the example descriptor used doesn't follow the developer guideline of using invalid bech32 addresses, as the RPC is not wallet-related and it's use-case is merely to look up state information (i.e. there is no danger of sending funds to a wrong address).~ For the sake of simplicity, the raw descriptor for an early coinbase payout address (block 9) is taken, i.e. it yields results even at an early stage of IBD. Happy to change that though if there are other suggestions.

29e983386b Fixes Bug in Transaction generation in ComplexMempool benchmark (Shorya)
Pull request description:
This fixes issues with `ComplexMempool` benchmark introduced in [#17292](https://github.com/bitcoin/bitcoin/pull/17292) , this stress test benchmarks performance of ancestor and descendant tracking of mempool graph algorithms on a complex Mempool.
This Benchmark first creates 100 base transactions and stores them in `available_coins` vector. `available_coins` is used for selecting ancestor transactions while creating 800 new transactions. For this a random transaction is picked from `available_coins` and some of its outputs are mapped to the inputs of the new transaction being created.
Now in case we exhaust all the outputs of an entry in `available_coins` then we need to remove it from `available_coins` before the next iteration of choosing a potential ancestor , it is now implemented with this patch.
As the index of the entry is randomly chosen from `available_coins` , In order to remove it from the vector , if index of the selected entry is not at the end of `available_coins` vector , it is swapped with the entry at the back of the vector , then the entry at the end of `available_coins` is popped out.
Earlier the code responsible for constructing outputs of the newly created transaction was inside the loop used for assigning ancestors to the transaction , which does some unnecessary work as it creates outputs of the transaction again and again , now it is moved out of the loop so outputs of the transaction are created just once before adding it to the final list of the transactions created. This one is a minor change to save some computation.
These changes have changed the `ComplexMempool` benchmark results on `bitcoin:master` as follows :

0c85dc30e6 p2p: Don't use timestamps from inbound peers (Martin Zumsande)
Pull request description:
`GetAdjustedTime()` (used e.g. in validation and addrman) returns a time with an offset that is influenced by timestamps that our peers have sent us in their version message.
Currently, timestamps from all peers are used for this.
However, I think that it would make sense to ignore the timedata samples from inbound peers, making it much harder for others to influence the Adjusted Time in a targeted way.
With the extra feeler connections (every 2 minutes on average) and extra block-relay-only connections (every 5 minutes on average) there are also now plenty of opportunities to gather a meaningful number of timedata samples from outbound peers.
There are some measures in place to prevent abuse: the `-maxtimeadjustment` parameter with a default of 70 minutes, warnings in cases of large deviations, only using the first 200 samples ([explanation](383d350bd5/src/timedata.cpp (L57-L72))), but I think that only using samples from outbound connections in the first place would be an additional safety measure that would make sense.
See also issue #4521 for further context and links: There have been several discussions in the past about replacing or abolishing the existing timedata system.

31ba1af74a Remove unused (and broken) functionality in SpanReader (Pieter Wuille)
Pull request description:
This removes the ability to set an offset in the `SpanReader::SpanReader` constructor, as the current code is broken since #23653. All call sites use `pos=0`, so it is actually unused. If future call sites need it, `SpanReader{a, b, c, d}` is equivalent to `SpanReader{a, b, c.subspan(d)}`.
It also removes the ability to deserialize from `SpanReader` directly from the constructor. This too is unused, and can be more idiomatically simulated using `(SpanReader{a, b, c} >> x >> y >> z)` instead of `SpanReader{a, b, c, x, y, z}`.

fa37e798b2 wallet: Replace confusing getAdjustedTime() with GetTime() (MarcoFalke)
Pull request description:
Setting `nTimeReceived` to the adjusted time has several issues:
* `m_best_block_time` is set to the "unadjusted" time, thus a comparison of the two times is like comparing apples to oranges. In the worst case this opens up an attack vector where remote peers can force a premature re-broadcast of wallet txs.
* The RPC documentation for `"timereceived"` doesn't mention that the network adjusted time is used, possibly confusing users when the time reported by RPC is off by a few seconds compared to their local timestamp.
Fix all issues by replacing the call with `GetTime()`. Also a style fix: Use non-narrowing integer conversion in the RPC method.

...by moving the try/catch out of LoadChainstate
I strongly recommend reviewing with the following git-diff flags:
--color-moved=dimmed_zebra --color-moved-ws=allow-indentation-change
...instead allow the caller to optionally pass in callbacks which are
triggered for certain events.
Behaviour change: The string "Verifying blocks..." was previously
printed for each chainstate in chainman which did not have an
effectively empty coinsview, now it will be printed once unconditionally
before we call VerifyLoadedChain.
This removes the ability to set an offset in the SpanReader constructor,
as the current code is broken. All call sites use pos=0, so it is actually
unused. If future call sites need it, SpanReader{a, b, c, d} is equivalent
to SpanReader{a, b, c.subspan(d)}.
It also removes the ability to deserialize from SpanReader directly from
the constructor. This too is unused, and can be more idiomatically
simulated using (SpanReader{a, b, c} >> x >> y >> z) instead of
SpanReader{a, b, c, x, y, z}.
This allows us to separate the initialization code from translations and
error reporting.
This change changes the caller semantics of LoadChainstate quite
drastically.
To see that this change doesn't change behaviour, observe that:
1. Prior to this change, LoadChainstate returned false only in the "bad
genesis block" failure case (by returning InitError()), indicating
that the caller should immediately bail. After this change, the
corresponding ERROR_BAD_GENESIS_BLOCK handler in src/init.cpp
maintains behavioue by also bailing immediately.
2. The failed_* temporary booleans were only used to break out of the
outer do/while(false) loop. They can therefore be safely removed.
I strongly recommend reviewing with the following git-diff flags:
--color-moved=dimmed_zebra --color-moved-ws=allow-indentation-change
[META] This commit is intended to be as close to a move-only commit as

A few variables that are passed in by value instead of by reference
deserve explanation:
- fReset and fReindexChainstate are both local variables in AppInitMain
and are not modified in the sequence
- fPruneMode, despite being a global, is only modified in
AppInitParameterInteraction, long before LoadChainstate is called

During a reorg, we re-check timelocks on all mempool entries using
CheckSequenceLocks(useExistingLockPoints=false) and remove any
now-invalid entries. CheckSequenceLocks() also mutates the LockPoints
passed in, and we update valid entries' LockPoints using
update_lock_points. Thus, update_lock_points(lp) needs to be called
right after CheckSequenceLocks(lp), otherwise we lose the data in lp.
commit bedf246 introduced a bug by separating those two loops.
