Currently the manpages are installed, but that is a bug. An upcoming commit
will avoid installing manpages for targets that aren't configured, which
removes the "install" target for fuzz builds.

Pull request description:
When building for fuzzing with multiprocess enabled, we were still trying to build `bitcoin-node`. This PR fixes that, by applying a similar check as for `bitcoin-gui`.
Before:
```
cmake -B build -DBUILD_FOR_FUZZING=ON -DWITH_MULTIPROCESS=ON
...

=================
Executables:

bitcoin-node (multiprocess) ......... ON
bitcoin-qt (GUI) .................... OFF
bitcoin-gui (GUI, multiprocess) ..... OFF
...
cmake --build build
...

```
After:
```
bitcoin-node (multiprocess) ......... OFF
```
And no `bitcoin-node` target gets built (not to be confused with `bitcoin_node`).

Previously, -nodebug cleared all prior -debug configurations in the
command line while allowing subsequent debug options to be applied.
However, -debug=0 and -debug=none completely disabled debugging,
even for categories specified afterward.
This commit ensures consistency by making -debug=0 and -debug=none
behave like -nodebug: they now clear previously set debug configurations
but do not disable debugging for categories specified later.

Our CMake toolchain for a Darwin cross build currently contains:
```bash
set(CMAKE_AR "/usr/bin/llvm-ar")
set(CMAKE_RANLIB "/usr/bin/llvm-ranlib")
set(CMAKE_STRIP "/usr/bin/llvm-strip")
set(CMAKE_OBJCOPY "arm64-apple-darwin-objcopy")
set(CMAKE_OBJDUMP "/usr/bin/llvm-objdump")
```
`objcopy` isn't currently used for the Darwin build (only for Linux and
splitting the debug symbols), but we shouldn't be producing a toolchain
file that refers to nonexistent tools.

Since `bech32::Encode` rejects uppercase letters, we're actually generating values in the `[33-126] - ['A'-'Z']` range.

b2e9fdc00f5c40c241a37739f7b73b74c2181e39 test: expect that files may disappear from /proc/PID/fd/ (Vasil Dimov)
Pull request description:
`get_socket_inodes()` calls `os.listdir()` and then iterates on the results using `os.readlink()`. However a file may disappear from the directory after `os.listdir()` and before `os.readlink()` resulting in a `FileNotFoundError` exception.
It is expected that this may happen for `bitcoind` which is running and could open or close files or sockets at any time. Thus ignore the `FileNotFoundError` exception.

This prevents intermittent failures - if the node hasn't processed
the inv from the outbound peer before the mocktime bump, the peer
won't be preferred after the other inv timeouts, failing the test .
Therefore, add a sync, just like there is one after the send_message
calls in the previous lines.
The legacy wallet will be able to solve output scripts where the
redeemScript or witnessScript is known, but does not know any of the
private keys involved in that script. These should be migrated to the
solvables wallet.
LegacySPKM would determine whether it could provide any script data to a
transaction through the use of the CanProvide function. Instead of
partially reversing signing logic to figure out the output scripts of
solvable things, we use the same candidate set approach in
GetScriptPubKeys() and instead filter the candidate set first for
things that are ISMINE_NO, and second with CanProvide(). This should
give a more accurate solvables wallet.
InferDescriptors can sometimes make descriptors which are actually
invalid and cannot be parsed. Detect and skip such descriptors by doing
a Parse() check before adding the descriptor to the wallet.
Instead of (partially) trying to reverse IsMine() to get the output
scripts that a LegacySPKM would track, we can preserve it in migration
only code and utilize it to get an accurate set of output scripts.
This is accomplished by computing a set of output script candidates from
map(Crypted)Keys, mapScripts, and setWatchOnly. This candidate set is an
upper bound on the scripts tracked by the wallet. Then IsMine() is used
to filter to the exact output scripts that LegacySPKM would track.
By changing GetScriptPubKeys() this way, we can avoid complexities in
reversing IsMine() and get a more complete set of output scripts.

Pull request description:
Put the generic parts from `StaticContentsSock` into a separate class `ZeroSock` so that they can be reused in other mocked `Sock` implementations.
Add a new `DynSock` whose `Recv()` and `Send()` methods can be controlled after the object is created. To achieve that, the caller/creator of `DynSock` provides to its constructor two pipes (FIFOs) - recv-pipe and send-pipe. Whatever data is written to recv-pipe is later received by `DynSock::Recv()` method and whatever data is written to the socket using `DynSock::Send()` can later be found in the send-pipe. For convenience there are also two methods to send and receive `CNetMessage`s.

Pull request description:
* This PR attempts to fix the duplicate coinbase weight reservation issue we currently have.
* Fixes#21950
We reserve 4000 weight units for coinbase transaction in `DEFAULT_BLOCK_MAX_WEIGHT`
7590e93bc7/src/policy/policy.h (L23)
And also reserve additional `4000` weight units in the default `BlockCreationOptions` struct.
7590e93bc7/src/node/types.h (L36-L40)
**Motivation**
- This issue was first noticed during a review here https://github.com/bitcoin/bitcoin/pull/11100#discussion_r136157411)
- It was later reported in issue #21950.
- I also came across the bug while writing a test for building the block template. I could not create a block template above `3,992,000` in the block assembler, and this was not documented anywhere. It took me a while to realize that we were reserving space for the coinbase transaction weight twice.
---
This PR fixes this by consolidating the reservation to be in a single location in the codebase.
This PR then adds a new startup option `-blockreservedweight` whose default is `8000` that can be used to lower or increase the block reserved weight for block header, txs count, coinbase tx.

Pull request description:
Part of orphan resolution project, see #27463.
Definitions:
- **Announcement** is a unique pair (wtxid, nodeid). We can have multiple announcers for the same orphan since #31397.
- **Size** is the weight of an orphan. I'm calling it "size" and "bytes" because I think we can refine it in the future to be memusage or be otherwise more representative of the orphan's actual cost on our memory. However, I am open to naming changes.
This is part 1/2 of a project to also add limits on orphan size and count. However, this PR **does not change behavior**, just adds internal counters/tracking and a fuzzer. I will also open a second PR that adds behavior changes, which requires updating a lot of our tests and careful thinking about DoS.

This PR is similar to https://github.com/bitcoin/bitcoin/pull/31337 and applies analogous changes to all dependency packages.
The issue was [recently noticed](https://github.com/bitcoin/bitcoin/pull/31661#discussion_r1923896475) when `-ffile-prefix-map` was added to the `libevent` package, which is built in OSS-Fuzz.
This PR replaces `-ffile-prefix-map` in all packages for consistency.
Fixes https://github.com/bitcoin/bitcoin/issues/31770.

faca7ac13215fd88b420feea8f06d7404f8fd067 ci: Bump fuzz task timeout (MarcoFalke)
Pull request description:
The fuzz task seems to be the most CPU intense task (going through GB of data through all fuzz inputs for all fuzz targets).
Normally, the task takes 44 minutes (example https://cirrus-ci.com/task/5077976091459584), but under higher load, it may take longer (https://cirrus-ci.com/task/5966231095738368).
I tried to move it to GHA to see how it compares, but it will be even slower there: https://github.com/maflcko/bitcoin-core-with-ci/actions/runs/13182526514/job/36796629409.
The CI machines were recently updated to increase the CI performance, so in theory they could be updated again, but this can take some time and seems like the wrong fix anyway, because it will just hide the problem:
Ideally fuzzing is fast and when evaluating a fuzz input takes more than 10 seconds, it feels more like a slow unit test loop. So ideally fuzz timeouts should be fixed (https://github.com/bitcoin/bitcoin/issues/31066, https://github.com/bitcoin/bitcoin/issues/30498, ...). However, this can also take time.
So temporarily bump the fuzz timeout for now.

No change for now, moving from map of NodeId->workset to
NodeId->PeerOrphanInfo struct that holds the workset.
In future commits, we will start tracking more things per-peer in the
orphanage.

Some of the networking constants defined in p2p_tx_download.py are more generally
defined in p2p.py
Also, rename the remaining ones to match ones defined in txdownloadman
