5d4999951e prevector: Avoid unnamed struct, which is a GNU extension (DesWurstes)
Pull request description:
Since we [started using](https://github.com/bitcoin/bitcoin/pull/7165) the `ax_cxx_compile_stdcxx.m4` macro we've been passing `[noext]` to indicate that we don't want to use an extended mode, i.e GNU extensions. Speaking to Cory he clarified that the intention was to "require only vanilla c++11 and turn _off_ extension support so they would fail to compile".
However in the codebase we are currently making use of some GNU extensions. We should either remove there usage, or at least amend our CXX compiler checks. I'd prefer the former.
#### anonymous structs
```bash
./prevector.h:153:9: warning: anonymous structs are a GNU extension [-Wgnu-anonymous-struct]
struct {
```
This is fixed in b849212c1e.
#### variadic macros
```bash
./undo.h:57:50: warning: must specify at least one argument for '...' parameter of variadic macro [-Wgnu-zero-variadic-macro-arguments]
::Unserialize(s, VARINT(nVersionDummy));
```
This is taken care of in #18087.
The `LOG_TIME_*` macros introduced in #16805 make use of a [GNU extension](https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html).
```bash
In file included from validation.cpp:22:
./logging/timer.h:99:99: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments]
BCLog::Timer<std::chrono::milliseconds> PASTE2(logging_timer, __COUNTER__)(__func__, end_msg, ## __VA_ARGS__)
^
./logging/timer.h:99:99: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments]

BCLog::Timer<std::chrono::seconds> PASTE2(logging_timer, __COUNTER__)(__func__, end_msg, ## __VA_ARGS__)
^
6 warnings generated.
```
This is fixed in 081a0ab64eb442bc85c4d4a4d3bc2c8e97ac2a6d and 612e8e138b97fc5ad2f38847300132a8fc423c3f.
#### prevention
To ensure that usage doesn't creep back in we can add [`-Wgnu`](https://clang.llvm.org/docs/DiagnosticsReference.html#wgnu) to our compile time flags, which will make Clang warn whenever it encounters GNU extensions.
This would close#14130.
Also related to #17230, where it's suggested we use a GNU extension, the `gnu::pure` attribute.

b56607a89b Remove CCoinsViewCache::GetValueIn(...) (practicalswift)
Pull request description:
Remove `CCoinsViewCache::GetValueIn(...)`.
Fixes#18858.
It seems like `GetValueIn` was added in #748 ("Pay-to-script-hash (OP_EVAL replacement)", merged in 2012) and the last use in validation code was removed in #8498 ("Near-Bugfix: Optimization: Minimize the number of times it is checked that no money...", merged in 2017).
`CCoinsViewCache::GetValueIn(…)` performs money summation like this:
```c++
CAmount CCoinsViewCache::GetValueIn(const CTransaction& tx) const
{
if (tx.IsCoinBase())
return 0;
CAmount nResult = 0;
for (unsigned int i = 0; i < tx.vin.size(); i++)
nResult += AccessCoin(tx.vin[i].prevout).out.nValue;
return nResult;
}
```
Note that no check is done to make sure that the resulting `nResult` is such that it stays within the money bounds (`MoneyRange(nResult)`), or that the summation does not trigger a signed integer overflow.
Proof of concept output:
```
coins.cpp:243:17: runtime error: signed integer overflow: 9223200000000000000 + 2100000000000000 cannot be represented in type 'long'
GetValueIn = -9221444073709551616
```
Proof of concept code:
```c++
CMutableTransaction mutable_transaction;
mutable_transaction.vin.resize(4393);
Coin coin;
coin.out.nValue = MAX_MONEY;
assert(MoneyRange(coin.out.nValue));
CCoinsCacheEntry coins_cache_entry;
coins_cache_entry.coin = coin;
coins_cache_entry.flags = CCoinsCacheEntry::DIRTY;
CCoinsView backend_coins_view;
CCoinsViewCache coins_view_cache{&backend_coins_view};
CCoinsMap coins_map;
coins_map.emplace(COutPoint{}, std::move(coins_cache_entry));
coins_view_cache.BatchWrite(coins_map, {});
const CAmount total_value_in = coins_view_cache.GetValueIn(CTransaction{mutable_transaction});
std::cout << "GetValueIn = " << total_value_in << std::endl;

Enable -Wconditional-uninitialized to warn on potentially uninitialized
reads.
Fix the sole such warning in Bitcoin Core in GetRdRand(): r1 would be
set to 0 on rdrand failure, so initializing it to 0 is a non-functional
change.

After upgrading the node, try to go back to the original version to make
sure that using a newver node version does not prevent the wallet file
from being downgraded again.
Apparently the -X flag doesn't work as expected in makensis v2.x
For example:
makensis -V2 share/setup.nsi -X'OutFile "test.exe"'
Will output:
OutFile expects 1 parameters, got 0.
Usage: OutFile install_output.exe
So let's instead construct the file using POSIX-compliant commands and
shell constructs
Also, mark feebumper bilingual_str as Untranslated
They are technical and have previously not been translated either.
It is questionable whether they can even appear in the GUI.
Common errors and warnings should be translated when displayed in the
GUI, but not translated when displayed elsewhere. The wallet method
CreateWalletFromFile does not know its caller, so this commit changes it
to return a bilingual_str to the caller.
This reverts commit 0933a37078 from
https://github.com/bitcoin/bitcoin/pull/18160 which no longer an optimization
since commit "gui: Avoid wallet tryGetBalances calls before TransactionChanged
or BlockTip notifications".

Pull request description:
This change is intended to make the bitcoin node and its rpc, network and gui interfaces more responsive while the wallet is in use. Currently, because the node's `cs_main` mutex is always locked before the wallet's `cs_wallet` mutex (to prevent deadlocks), `cs_main` currently stays locked while the wallet does relatively slow things like creating and listing transactions.
Switching the lock order so `cs_main` is acquired after `cs_wallet` allows `cs_main` to be only locked intermittently while the wallet is doing slow operations, so the node is not blocked waiting for the wallet.
To review the present PR, most of getting right the move is ensuring any `LockAssertion` in `Chain::Lock` method is amended as a `LOCK(cs_main)`. And in final commit, check that any wallet code which was previously locking the chain is now calling a method, enforcing the lock taking job. So far the only exception I found is `handleNotifications`, which should be corrected.

interfaces::Wallet::tryGetBalances was recently updated in
https://github.com/bitcoin/bitcoin/pull/18160 to avoid computing balances
internally, but this not efficient as it could be with #10102 because
tryGetBalances is an interprocess call.
Implementing the TransactionChanged / BlockTip check outside of tryGetBalances
also allows tryGetBalances to be simplified in next commit 'Revert "gui: Avoid
Wallet::GetBalance in WalletModel::pollBalanceChanged"'.
Disable copying of CWalletTx objects to prevent bugs where instances get copied
in and out of the mapWallet map and fields are updated in the wrong copy.
