7766dd280d9a4a7ffdfcec58224d0985cfd4169b net: Replace ifname check with IFF_LOOPBACK in Discover (laanwj)
Pull request description:
Checking the interface name is kind of brittle. In the age of network namespaces and containers, there is no reason a loopback interface can't be called differently.
Check for the `IFF_LOOPBACK` flag to detect loopback interface instead.
Also remove a misleading comment in Discover's doc comment.

42fb5311b19582361409d65c6fddeadbee14bb97 rpc: return warnings as an array instead of just a single one (stickies-v)
Pull request description:
The RPC documentation for `getblockchaininfo`, `getmininginfo` and `getnetworkinfo` states that "warnings" returns "any network and blockchain warnings". In practice, only a single warning (i.e. the latest one that is set) is returned, the other ones are ignored.
Fix that by returning all warnings as an array.
As a side benefit, clean up the GetWarnings() logic.
Since this PR changes the RPC result schema, I've added release notes. Users can temporarily revert to the old results by using `-deprecatedrpc=warnings`, until it's removed in a future version.
---
Some historical context from git log:
- when `GetWarnings` was introduced in 401926283a200994ecd7df8eae8ced8e0b067c46, it was used in the `getinfo` RPC, where only a [single error/warning was returned](401926283a (diff-7442c48d42cd5455a79915a0f00cce5e13359db46437a32b812876edb0a5ccddR250)) (similar to how it is now).
- later on, "warnings" RPC response fields were introduced, e.g. in ef2a3de25c882396e1776b554878d2784b6b7391, with the description [stating](ef2a3de25c (diff-1021bd3c74415ad9719bd764ad6ca35af5dfb33b1cd863c0be49bdf52518af54R411)) that it returned "any network warnings" but in practice still only a single warning was returned

Previously, our Android builds were geared towards generating APKs,
which relied on Qt. However, after migrating to C++20, compiling for
Android became unfeasible due to Qt 5.15's compatibility limitations
with NDK only up to r25, which includes an outdated embedded libc++.
All removed stuff will be reinstated after migrating the build system to
CMake and upgrading Qt to version 6.x."

due to an assert. This has been replaced with logging the error,
disconnecting the peer, and returning early.

Pull request description:
It seems modern compilers don't realize that all invocations of operator""_mst can be evaluated at compile time, despite the `constexpr` keyword.
Since C++20, we can force them to evaluate at compile time using `consteval`, turning all the miniscript type constants into actual compile-time constants.
This should give a nice but not very important speedup for miniscript logic, but it's also a way to start testing C++20 features.

Due to a bug in the legacy wallet, the p2sh maximum script size limit is also imposed
on 'p2sh-segwit' and 'bech32' redeem scripts.
Although redeem scripts over MAX_SCRIPT_ELEMENT_SIZE bytes are technically valid for
segwit output types, we don't want to enable this feature in legacy wallets for the
following reasons:
1) It introduces a compatibility-breaking change requiring downgrade protection; older
wallets would be unable to interact with these "new" legacy wallets.
2) Considering the ongoing deprecation of the legacy spkm, this issue adds another
good reason to transition towards descriptors.
This exercises the bug fixed by previous commits, where
we were unable to generate and sign for segwit redeem scripts
(in this case multisig redeem scripts) longer than 520 bytes.
and also, this adds coverage for legacy 15-15 multisig script
generation and signing.
The process currently fails to sign redeem scripts that are longer than
520 bytes. Even when it shouldn't. The 520 bytes redeem scripts limit
is a legacy p2sh rule, and not a segwit limitation.
Segwit redeem scripts are not restricted by the script item size limit.
The reason why this occurs, is the usage of the same keystore used by
the legacy spkm. Which contains blockage for any redeem scripts longer
than the script item size limit.
The multisig script generation process currently fails when
the user exceeds 15 keys, even when it shouldn't. The maximum
number of keys allowed for segwit redeem scripts (p2sh-segwit
and bech32) is 20 keys.
This is because the redeem script placed in the witness is not
restricted by the item size limit.
The reason behind this issue is the utilization of the legacy
p2sh redeem script restrictions on segwit ones. Redeem scripts
longer than 520 bytes are blocked from being inserted into the
keystore, which causes the signing process and the descriptor
inference process to fail.
This occurs because the multisig generation flow uses the same
keystore as the legacy spkm (FillableSigningProvider), which
contains the 520-byte limit.
And also, simplified the test a bit by re-using the already existing 'wallet_multi'
(instead of creating a new one). Plus, removed the 'is_bdb_compiled()' calls
which were there basically to check if the test has the wallet compiled or not.
The function exists merely to check that the node2's wallet
received the transactions created during all the 'do_multisig()'
calls.
It was created as a standalone function because 'getbalance()'
only returns something when transactions are confirmed. So,
the rationale on that time was to have a method mining blocks
to confirm the recently created transactions to be able to
check the incoming balance.
This is why we have the "moved" class field.
This change removes all the hardcoded amounts and verifies
node2 balance reception directly inside 'do_multisig()'.
Cleaning up the test in the following ways:
* Generate priv-pub key pairs used for testing only once (instead of doing it 4 times).
* Simplifies 'wmulti' wallet creation, load and unload process.
* Removes confusing class members initialized and updated inside a nested for-loop.
* Simplifies do_multisig() outpoint detection:
The outpoint index information is already contained in MiniWallet's
`send_to` return value dictionary as "sent_vout".

It seems modern compilers don't realize that all invocations of operator""_mst
can be evaluated at compile time, despite the constexpr keyword.
Since C++20, we can force them to evaluate at compile time, turning all the
miniscript type constants into actual compile-time constants.
It appears that MSVC does not support consteval operator"" when used inside
certain expressions. For the few places where this happens, define a
constant outside the operator call.

As described in #10542 (and numerous other places), message signing in
Bitcoin Core only supports message signing using P2PKH addresses, at
least until a new message-signing standard is agreed upon.
Therefore update the possibly-misleading error message presented to the
user in the GUI to detail more specifically the reason their message
cannot be signed, in the case that a non P2PKH address is entered.
Now that CXXFLAGS are back in user control, I don't think there's a

ec1f1abfefa281e62bb876aa1c4738d576ef9a47 test:Validate UTXO snapshot with coin_height > base_height & amount > money_supply (jrakibi)
Pull request description:
### Ensure snapshot loading fails for coins exceeding base height
**Objective**: This test verifies that snapshot loading is correctly rejected for coins with a height greater than the base height.
**Update**:
- Added `test_invalid_snapshot_wrong_coin_code` to `feature_assumeutxo.py`.
- The test artificially sets a coin's height above 299 in a snapshot and checks for load failure.
- Edit: Added a test case for outputs whose amounts surpass the MAX_MONEY supply limit.
This implementation addresses the request for enhancing `assumeutxo` testing as outlined in issue #28648
---
**Edit: This is an explanation on how I arrive at content values: b"\x84\x58" and b"\xCA\xD2\x8F\x5A"**
You can use this tool to decode the utxo snapshot https://github.com/jrakibi/utxo-live
Here’s an overview of how it’s done:
The serialization format for a UTXO in the snapshot is as follows:
1. Transaction ID (txid) - 32 bytes
2. Output Index (outnum)- 4 bytes
3. VARINT (code) - A varible-length integer encoding the height and whether the transaction is a coinbase. The format of this VARINT is (height << 1) | coinbase_flag.
4. VARINT (amount_v) - A variable-length integer that represents a compressed format of the output amount (in satoshis).
For the test cases mentioned:
* **`b"\x84\x58"`** - This value corresponds to a VARINT representing the height and coinbase flag. Once we decode this code, we can extract the height and coinbase using `height = code_decoded >> 1` and `coinbase = code_decoded & 0x01`. In our case, with code_decoded = 728, it results in `height = 364` and `coinbase = 0`.
* **`b"\xCA\xD2\x8F\x5A"`** - This byte sequence represents a compressed amount value. The decompression function takes this value and translates it into a full amount in satoshis. In our case, the decompression of this amount translates to a number larger than the maximum allowed value of coins (21 million BTC)
