Pull request description:
This is an attempt at mitigating https://github.com/bitcoin/bitcoin/issues/25258 , which is a revival of https://github.com/bitcoin/bitcoin/pull/10984, which is a revival of https://github.com/bitcoin/bitcoin/pull/9447.
This PR attempts to mitigate a single case, where high bandwidth peers can bail us out of a flakey
peer not completing blocks for us. We allow up to 2 additional getblocktxns requests per unique block.
This would hopefully allow the chance for an honest high bandwidth peer to hand us the transactions
even if the first in flight peer stalls out.
In contrast to previous effort:
1) it will not help if subsequent peers send block headers only, so only high-bandwidth peers this time. See: https://github.com/bitcoin/bitcoin/pull/10984/files#diff-6875de769e90cec84d2e8a9c1b962cdbcda44d870d42e4215827e599e11e90e3R1411
2) `MAX_GETBLOCKTXN_TXN_AFTER_FIRST_IN_FLIGHT` is removed, in favor of aiding recovery during turbulent mempools
3) We require one of the 3 block fetching slots to be an outbound peer. This can be the original offering peer, or subsequent compact blocks given by high bandwidth peers.

To avoid `bad-txns-premature-spend-of-coinbase` error,
when getting a utxo (using `get_utxo`) to create a new
transaction `get_utxo` shouldn't return (if possible)
by default immature coinbase.

A single outbound slot is required, so if the first two slots
are taken by inbound in-flights, the node will reject additional
unless they are coming from outbound.
This means in the case where a fast sybil peer is attempting to
stall out a node, a single high bandwidth outbound peer can
mitigate the attack.
Disable boost multi index safe mode by default when configuring with
--enable-debug.
This option can cause transactions to take a long time to be accepted
into the mempool under certain conditions; iterator destruction takes
O(n) time vs O(1) as they are stored in a singly linked list. See
27586 for more information.
Re-enable it on the CI builds which previously had it enabled.
Re-enable it on the msan fuzz target so that we have fuzz tasks testing
with it enabeld and disabled in this repo.

Use of -stdlib++-isystem gets rid of any system c++ header include paths and
negates the need for this option. In newer versions of clangs the combo
produces a warning.
The 'm_synced' flag enables 'BlockConnected' events to be processed by
the index. If we set the flag before calling 'CustomInit', we could be
dispatching a block connected event to an uninitialized index child
class.
e.g. BlockFilterIndex, initializes the next filter position
inside 'CustomInit'. So, if `CustomInit` is not called prior receiving
the block event, the index will use 'next_filter_position=0' which
overwrites the first filter in disk.

fb2a3a70e860aa87fb7a21f6554ed9f3ce901e2d rpc: add descriptorprocesspsbt rpc (ishaanam)
Pull request description:
This PR implements an RPC called `descriptorprocesspsbt`. This RPC is based off of `walletprocesspsbt`, but instead of interacting with the wallet to update, sign and finalize a psbt, it instead accepts an array of output descriptors and uses that information along with information from the mempool, txindex, and the utxo set to do so. `utxoupdatepsbt` also updates a psbt in this manner, but doesn't sign or finalize it. Because of this overlap, a helper function that is added in this PR is called by both `utxoupdatepsbt` and `descriptorprocesspsbt`. Whether or not the helper function signs a psbt is dictated by if the HidingSigningProvider passed to it contains any private information. There is also a test added in this PR for this new RPC that uses p2wsh, p2wpkh, and legacy outputs.

Pull request description:
This requires a linux kernel of `3.17`+, 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, going 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:
> * The getentropy and getrandom functions, and the <sys/random.h> header
file have been added.
and we already require `2.27` or later.
All that being said, I don't think you would encounter a current day (+~6 months from now)
system, running with kernel headers older than 3.17 (released 2014) but also having a
glibc of 2.27+ (released 2018)?
Removing this (our only) use of `syscall()` also means we can drop a workaround in our MSAN jobs.
If this is merged, I'll drop the [same workaround in oss-fuzz](25946a5448/projects/bitcoin-core/build.sh (L49-L56)).

c44f3f231988dc05c4c7a8a96bc2e7b1a54da277 test: Explicitly specify directory where to search tests for (Hennadii Stepanov)
Pull request description:
For out-of-source builds, the `test/functional/test_runner.py` is supposed to be run from the build directory which allows it to pick the `test/config.ini` file generated by the build system. Currently, it works accidently for the following reasons:
- on POSIX systems, when running a created by Autoconf symlink to the `test/functional/test_runner.py` in the source directory, it actually has the source directory location in the `sys.path`.
- on Windows (the `build_msvc` directory) VS project puts and copies every build artifact into the source tree (which is wrong and ugly).
This PR makes `test/functional/test_runner.py` work from a build directory in any form (a symbolic link, a hard link, a copy) on _all_ supported platforms, which is highly desirable in the upcoming [CMake-based build system](https://github.com/bitcoin/bitcoin/pull/25797).
For the current master branch, this PR has no behaviour change.
Required for https://github.com/hebasto/bitcoin/pull/15.
---
**Steps to reproduce the issue**
While the issue is mostly specific to Windows and CMake builds, it is still possible to reproduce it on the current master branch.
1. Make an out-of-source build:
```
$ ./autogen.sh
$ mkdir ../build && cd ../build
$ ../bitcoin/configure
$ make
```
2. Note that Autoconf created a symbolic link `test/functional/test_runner.py` in the `../build` directory:
```
$ ls -l test/functional/test_runner.py
lrwxrwxrwx 1 hebasto hebasto 47 May 5 17:40 test/functional/test_runner.py -> ../../../bitcoin/test/functional/test_runner.py
```
which works flawlessly.
3. However, replacing this symbolic link with a hard link or a copy of `test/functional/test_runner.py` from the source tree will cause the following error:
```
$ cp ../bitcoin/test/functional/test_runner.py test/functional/test_runner.py
$ ls -l test/functional/test_runner.py
$ ./test/functional/test_runner.py

fa5831bd6f940c4afb43ff625ba4fa6c641e999a build: Do not define `ENABLE_ZMQ` when ZMQ is not available (Hennadii Stepanov)
Pull request description:
A new behavior is consistent with the other optional dependencies.
The source code contains `#if ENABLE_ZMQ` lines only:
```
$ git grep ENABLE_ZMQ -- src/*.cpp
src/init.cpp:#if ENABLE_ZMQ
src/init.cpp:#if ENABLE_ZMQ
src/init.cpp:#if ENABLE_ZMQ
src/init.cpp:#if ENABLE_ZMQ
src/init.cpp:#if ENABLE_ZMQ
```
Change in description line -- "Define to 1..." --> "Define this symbol.." -- is motivated by the fact that the actual value of the defined `ENABLE_ZMQ` macro does not matter at all.

Since the kernel library no longer depends on the system file, move it
to the common library instead in accordance to the diagram in
doc/design/libraries.md.
With the previous move of AlertNotify out of the validation file, and
thus out of the kernel library, ScheduleBatchPriority is the last
remaining function used by the kernel library from util/system. Move it
to its own file, such that util/system can be moved out of the util
library in the following few commits.
Moving util/system out of the kernel library removes further networking
as well as shell related code from it.

To avoid `bad-txns-premature-spend-of-coinbase` error,
when getting a utxo (using `get_utxo`) to create a new
transaction `get_utxo` shouldn't return by default
immature coinbase.

Pull request description:
If a peer received an `inv` about a transaction, which was included in a block before receiving the corresponding `getdata`, it can be beneficial to send this transaction to the peer to aid compact block relay.
Add a test for this to avoid breaking it in the future.

Pull request description:
In the code we do not use string literals.
Also a check for `DTRACE_PROBE7` macro has been added as not all systems define`DTRACE_PROBE{6,7,8,9,10,11,12}` macros (e.g., FreeBSD).

Pull request description:
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.

043fcb0b053eee6021cc75e3d3f41097f52698c0 wallet: bugfix, GetNewCursor() misses to provide batch ptr to BerkeleyCursor (furszy)
Pull request description:
Decoupled from #26644 so it can closed in favor of #26715.
Basically, with bdb, we can't make a write operation while we are traversing the db with the same db handler. These two operations are performed in different txn contexts and cause a deadlock.
Added coverage by using `EraseRecords()` which is the simplest function that executes this process.
To replicate it, need bdb support and drop the first commit. The test will run forever.

This is a change in behavior so that if for some reason we request a block from a peer, we don't allow an unsolicited CMPCT_BLOCK announcement for that same block to cause a request for a full block from the uninvited peer (as some type of request is already outstanding from the original peer)
