4614332fc4 test: remove unnecessary finalizepsbt rpc calls (ismaelsadeeq)
e3d484b603 wallet rpc: return final tx hex from walletprocesspsbt if complete (Matthew Zipkin)
Pull request description:
See https://github.com/bitcoin/bitcoin/pull/28363#discussion_r1315753887
`walletprocesspsbt` currently returns a base64-encoded PSBT and a boolean indicating if the tx is "complete". If it is complete, the base64 PSBT can be finalized with `finalizepsbt` which returns the hex-encoded transaction suitable for `sendrawtransaction`.
With this patch, `walletprocesspsbt` return object will ALSO include the broadcast-able hex string if the tx is already final. This saves users the extra step of calling `finalizepsbt` assuming they have already inspected and approve the transaction from earlier steps.

Pull request description:
This PR proposes a clean up of the relationship between block storage and the chainstate objects, by moving the decision of whether to store a block on disk to something that is not chainstate-specific. Philosophically, the decision of whether to store a block on disk is related to validation rules that do not require any UTXO state; for anti-DoS reasons we were using some chainstate-specific heuristics, and those have been reworked here to achieve the proposed separation.
This PR also fixes a bug in how a chainstate's `setBlockIndexCandidates` was being initialized; it should always have all the HAVE_DATA block index entries that have more work than the chain tip. During startup, we were not fully populating `setBlockIndexCandidates` in some scenarios involving multiple chainstates.
Further, this PR establishes a concept that whenever we have 2 chainstates, that we always know the snapshotted chain's base block and the base block's hash must be an element of our block index. Given that, we can establish a new invariant that the background validation chainstate only needs to consider blocks leading to that snapshotted block entry as potential candidates for its tip. As a followup I would imagine that when writing net_processing logic to download blocks for the background chainstate, that we would use this concept to only download blocks towards the snapshotted entry as well.

Nobody is pushing direct to guix.sigs, nor should they, as that
bypasses CI.
Use a newer example for the testing issue.
Don't duplicate the bitcoincore.org doc instructions.
The thread does not only load blocks, it loads the mempool and,
in a future commit, will start the indexes as well.
Also, renamed the 'ThreadImport' function to 'ImportBlocks'
And the 'm_load_block' class member to 'm_thread_load'.

Pull request description:
Currently when we load a wallet, we just iterate through all of the records in the database and add them completely statelessly. However we have some records which do rely on other records being loaded before they are. To deal with this, we use `CWalletScanState` to hold things temporarily until all of the records have been read and then we load the stateful things.
However this can be slow, and with some future improvements, can cause some pretty drastic slowdowns to retain this pattern. So this PR changes the way we load records by choosing to load the records in a particular order. This lets us do things such as loading a descriptor record, then finding and loading that descriptor's cache and key records. In the future, this will also let us use `IsMine` when loading transactions as then `IsMine` will actually be working as we now always load keys and descriptors before transactions.
In order to get records of a specific type, this PR includes some refactors to how we do database cursors. Functionality is also added to retrieve a cursor that will give us records beginning with a specified prefix.
Lastly, one thing that iterating the entire database let us do was to find unknown records. However even if unknown records were found, we would not do anything with this information except output a number in a log line. With this PR, we would no longer be aware of any unknown records. This does not change functionality as we don't do anything with unknown records, and having unknown records is not an error. Now we would just not be aware that unknown records even exist.

Pull request description:
Add an RPC to get prioritised transactions (also tells you whether the tx is in mempool or not), helping users clean up `mapDeltas` manually. When `CTxMemPool::PrioritiseTransaction` sets a delta to 0, remove the entry from `mapDeltas`.
Motivation / Background
- `mapDeltas` entries are never removed from mapDeltas except when the tx is mined in a block or conflicted.
- Mostly it is a feature to allow `prioritisetransaction` for a tx that isn't in the mempool {yet, anymore}. A user can may resbumit a tx and it retains its priority, or mark a tx as "definitely accept" before it is seen.
- Since #8448, `mapDeltas` is persisted to mempool.dat and loaded on restart. This is also good, otherwise we lose prioritisation on restart.
- Note the removal due to block/conflict is only done when `removeForBlock` is called, i.e. when the block is received. If you load a mempool.dat containing `mapDeltas` with transactions that were mined already (e.g. the file was saved prior to the last few blocks), you don't delete them.
- Related: #4818 and #6464.
- There is no way to query the node for not-in-mempool `mapDeltas`. If you add a priority and forget what the value was, the only way to get that information is to inspect mempool.dat.
- Calling `prioritisetransaction` with an inverse value does not remove it from `mapDeltas`, it just sets the value to 0. It disappears on a restart (`LoadMempool` checks if delta is 0), but that might not happen for a while.
Added together, if a user calls `prioritisetransaction` very regularly and not all those transactions get mined/conflicted, `mapDeltas` might keep lots of entries of delta=0 around. A user should clean up the not-in-mempool prioritisations, but that's currently difficult without keeping track of what those txids/amounts are.

Pull request description:
Show an error on startup if a bitcoin datadir that is being used contains a `bitcoin.conf` file that is ignored. There are two cases where this could happen:
- One case reported in [#27246 (comment)](https://github.com/bitcoin/bitcoin/issues/27246#issuecomment-1470006043) happens when a `bitcoin.conf` file in the default datadir (e.g. `$HOME/.bitcoin/bitcoin.conf`) has a `datadir=/path` line that sets different datadir containing a second `bitcoin.conf` file. Currently the second `bitcoin.conf` file is ignored with no warning.
- Another way this could happen is if a `-conf=` command line argument points to a configuration file with a `datadir=/path` line and that path contains a `bitcoin.conf` file, which is currently ignored.
This change only adds an error message and doesn't change anything about way settings are applied. It also doesn't trigger errors if there are redundant `-datadir` or `-conf` settings pointing at the same configuration file, only if they are pointing at different files and one file is being ignored.

This requires a linux kernel of 3.17.0+, which seems entirely
reasonable. 3.17 went EOL in 2015, and the last supported 3.x kernel
(3.16) went EOL > 4 years ago, in 2020. For reference, the current
oldest maintained kernel is 4.14 (released 2017, EOL Jan 2024).
Support for `getrandom()` (and `getentropy()`) was added to
glibc 2.25, https://sourceware.org/legacy-ml/libc-alpha/2017-02/msg00079.html,
and we already require 2.27+.
All that being said, I don't think you would encounter a current day
system, running with kernel headers older than 3.17 (released 2014) but
also having a glibc of 2.27+ (released 2018).

It is a bit frustrating to write valid C++ code only to realize that g++-8 fails to parse it later on.
The only non-EOL operating system still shipping with g++-8 is CentOS Stream 8. I think it is reasonable for users of affected Linux distributions to:
* Upgrade their operating system, or compiler to a supported version.
* Alternatively, stay with a previous release of Bitcoin Core as long as it is supported.

Our compile documentation isn't the right place for genric binary
hardening notes, which are neither particularly Bitcoin-Core specific,
or as relevant as they might have once been, i.e non-executable stacks
are now just the norm.
Just remove the notes for now, if someone has
something more interesting/Bitcoin Core specific, it could be added in
separate documentation in the future (maybe into the devwiki or
similar).

fa29651c3f doc: Rework build-unix.md (MarcoFalke)
Pull request description:
The doc has many issues:
* The fist section contains outdated non-existing and confusing configure flags like `--enable-cxx` and `--disable-shared`, as well as edge-case expert options such as `BDB_PREFIX`. Fix that by removing the section and adding notes elsewhere, if applicable.
* There are links to the depends system before instructions on how to simply build from system packages. Fix that by moving that later.
* Also, remove sections that are duplicate with other depends READMEs.

7014e08015 doc: remove mention of glibc 2.10+ (fanquake)
Pull request description:
We already require glibc 2.27+, so mentioning a much older version here is redundant.
