Don't enable `-Werror` (in the CI) for compilers at least older than
our current release compiler (GCC 10). It provides little-to-no value,
other than turning compiler bugs & false positives into build failures,
and we aren't going to mutate perfectly fine/working code, for the sake
of avoid a warning that shouldn't even exist.
I also do not see the point of playing whack-a-mole and turning off various
warnings/trying to further work around the broken compiler, just to
acheive warningless builds for the sake of warningless builds.
One anecdote from "How SQLite Is Tested":
> Static analysis has found a few bugs in SQLite, but those are the
> exceptions. More bugs have been introduced into SQLite while trying
> to get it to compile without warnings than have been found by static

Now that Size() performs internal consistency checks,
it will rightfully fail (and assert) when dealing with
a corrupted AddrMan. Therefore remove this check.
87f11ef47fea31d51bcc3f5df68f78fb28e3d8dd refactor: use `Hash` helper for double-SHA256 calculations (Sebastian Falbesoner)
Pull request description:
We have two helper templates `Hash(const T& in1)` and `Hash(const T& in1, const T& in2)` available for calculating the double-SHA256 hash of one object or two concatenated objects, respectively:
b5868f4b1f/src/hash.h (L74-L89)
This PR uses them in order to increase readability and simplify the code. As in #15294 (which inspired this PR, doing the same for RIPEMD160), the helper is not utilized in validation.cpp and script/interpreter.cpp to avoid touching consensus-relevant code.

dfc01ccd73e1f12698278d467c241f398da9fc7d net: simplify the call to vProcessMsg.splice() (Vasil Dimov)
Pull request description:
At the time when
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), it);
```
is called, `it` is certainly `pnode->vRecvMsg.end()` which makes the call equivalent to:
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), pnode->vRecvMsg.end());
```
which is equivalent to:
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg);
```
Thus, use the latter. Further, maybe irrelevant, but the latter has constant complexity while the original code is `O(length of vRecvMsg)`.

Pull request description:
AddrMan currently doesn't track the number of its entries by network, it only knows the total number of addresses. This PR makes AddrMan keep track of these numbers, which would be helpful for multiple things:
1. Allow to specifically add fixed seeds to AddrMan of networks where we don't have any addresses yet - even if AddrMan as a whole is not empty (partly fixing #26035). This is in particular helpful if the user abruptly changes `-onlynet` settings (such that addrs that used to be reachable are no longer and vice versa), in which case they currently could get stuck and not find any outbound peers. The second commit of this PR implements this.
1. (Future work): Add logic for automatic connection management with respect to networks - such as making attempts to have at least one connection to each reachable network as suggested [here](https://github.com/bitcoin/bitcoin/issues/26035#issuecomment-1249420209). This would involve requesting an address from a particular network from AddrMan, and expanding its corresponding function `AddrMan::Select()` to do this requires internal knowledge of the current number of addresses for each network and table to avoid getting stuck in endless loops.
1. (Future work): Perhaps display the totals to users. At least I would find this helpful to debug, the existing option (`./bitcoin-cli -addrinfo`) is rather indirect by doing the aggregation itself in each call, doesn't distinguish between new and tried, and being based on `AddrMan::GetAddr()` it's also subject to a quality filter which we probably don't want in this spot.

In fact, this PR restores behavior that was before bitcoin/bitcoin#22646, and that behavior looks more optimal.
As an outcome, the `contrib/guix/libexec/build.sh` does not spend resources to build binaries which are not a part of the release package.

a24e633339c45eaca28fc7af0488956332ac300c refactor: rpc: set TxToJSON default verbosity to SHOW_DETAILS (stickies-v)
Pull request description:
`TxToJSON()` and `TxToUniv()` are only to be called when we want to decode the transaction (i.e. its details) into JSON. If `TxVerbosity` is `SHOW_TXID`, the function should not have been (and currently is not) called in the first place.
There is no behaviour change, current logic simply assumes anything less than `TxVerbosity::SHOW_DETAILS_AND_PREVOUT` equals `TxVerbosity::SHOW_DETAILS`. With this change, the assumptions and intent become more explicit.

The previous behavior, skipping some L3 DisconnectBlock calls,
but still attempting to reconnect these blocks at L4, makes
ConnectBlock assert.
The variable skipped_l3_checks is introduced because even with an
insufficient cache for the L3 checks, the L1/L2 checks in the same
loop should still be completed.
Fixes#25563.

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
In certain circumstances, we may want to flush chainstate data to disk without
emptying `cacheCoins`, which affects performance. UTXO snapshot
activation is one such case, as we populate `cacheCoins` with the snapshot
contents and want to persist immediately afterwards but also enter IBD.
See also #15265, which makes the case that under normal operation a
flush-without-erase doesn't necessarily add much benefit. I open this PR
even in light of the previous discussion because (i) flush-without-erase
almost certainly provides benefit in the case of snapshot activation (especially
on spinning disk hardware) and (ii) this diff is fairly small and gives us convenient
options for more granular cache management without changing existing policy.
See also #15218.

Pull request description:
This was done in the context of https://github.com/bitcoin/bitcoin/pull/25284 , but I think it also makes sense standalone.
The basic idea is that serialization type should not be initialized when it is not needed. Same for the serialization version.
So do this here for `AutoFile` and `HashVerifier`. `CAutoFile` and `CHashVerifier` remain in places where it is not yet possible.

Pull request description:
This PR removes the `--enable-upnp-default` and `--enable-natpmp-default` options from configure.
It's odd to me that we maintain configure-time options for setting the default port-forwarding runtime state (but no other similar options), and I'm not sure what use-case it satisfies, that can't be achieved by multiple other means. I also doubt that we'll ever restart using these in release builds, or turning on any of this by default.
I think the only scenario these options would be used is when you want to compile your own binaries (we don't use them in Guix), with port-forwarding on by default, but otherwise can't or don't want to use a `.conf` file, can't or don't want to pass command line options at runtime, and also don't want to modify the source code?
