bb1c84082c Remove the build_msvc/testconsensus project (Aaron Clauson)
Pull request description:
The testconsensus project is not integral to the Bitcoin Core code. It was originally added as a quick and dirty demo of how to do a consensus check with the msvc build. There are better examples.
PR #23438 made a change that caused a compiler error with the buildmsvc/testconsensus code. Rather than leave it hanging around to incur potential bitrot, or further PR build failures, it should be removed.

This updates build-unix for the descriptor wallet, and prepares for
eventual legacy wallet deprecation.
- Move 'descriptor wallet' dependencies above legacy wallet deps both
for Debian and Fedora.
- Explicitly mention 'legacy wallet' where referring to the BerkeleyDB
wallet. Shorten BerkeleyDB instruction to a single paragraph.

Makes the test more minimal. We're just trying to test that our package
sanitization logic is correct. Now that this code lives in its own
function (rather than inside of AcceptMultipleTransactions), there's no
need to call ProcessNewPackage to test this.
No change in behavior, because package transactions would not be going
through the rbf logic in PreChecks anyway (BIP125 is currently disabled
for package acceptance, see ATMPArgs).
We draw the line here because each individual transaction in package
validation still goes through all PreChecks. For example, checking that
one's own conflicts and dependencies are disjoint (a consensus check)
and individual transaction mempool ancestor/descendant limits.
The aliases are leftover from a previous MOVEONLY refactor - they are
unnecessary and removing them reduces the diff for splitting out mempool
Checks from PreChecks, making RBF variables MemPoolAccept-wide, etc.

The tests `streams_tests/streams_buffered_file` and `streams_tests/streams_buffered_file_rand`
did not use a the temporary directory provided by `BasicTestingSetup`, so it was not possible
to execute multiple of them in parallel. This fixes that.
To reproduce, run
```sh
parallel --halt now,fail=1 './src/test/test_bitcoin --run_test=streams_tests/streams_buffered_file_rand' -- ::: {1..1000}
```
This executes the test 1000 times, one job per CPU. It works on that commit but mergebase fails quickly.
80dc829be7 tests: Calculate fees more similarly to CFeeRate::GetFee (Andrew Chow)
ce2cc44afd tests: Test for assertion when feerate is rounded down (Andrew Chow)
0fbaef9676 fees: Always round up fee calculated from a feerate (Andrew Chow)
Pull request description:
When calculating the fee for a feerate, it is possible that the final calculation will have fractional satoshis. Currently those are ignored via truncation which results in the absolute fee being rounded down. Rounding down is problematic because it results in a feerate that is slightly lower than the feerate represented by the `CFeeRate` object. A slightly lower feerate particularly causes issues for coin selection as it can trigger an assertion error. To avoid potentially underpaying the feerate (and the assertion), always round up the calculated fee.
A test is added for the assertion, along with a comment explaining what happens.
It is unlikely that a user can trigger this as it requires a very specific set of rounding errors to occur as well as the transaction not needing any change and being right on the lower bound of the exact match window. However I was able to trigger the assertion while running coin selection simulations, albeit after thousands of transactions and with some weird feerates.

CTxMemPool::check() will carry out internal consistency checks 1/n times,
where n is set by the `-checkmempool` configuration option. By default,
mempool consistency checks are disabled entirely on mainnet.
Therefore, this change has no effect on mainnet nodes running with
default configuration. It simply removes the responsibility to trigger
mempool consistency checks from net_processing.
This just calls through to AcceptToMemoryPool() internally, and is currently unused.
Also add a new transaction validation failure reason TX_NO_MEMPOOL to
indicate that there is no mempool.
User-facing error messages should not leak internal implementation
details like function names. Update the MEMPOOL_REJECTED error string
from "Transaction rejected by AcceptToMemoryPool" to the more generic
"Transaction rejected by mempool". Also update the MEMPOOL_ERROR error
message from "AcceptToMemoryPool failed" to the more precise "Mempool
internal error" since this error indicates and internal (e.g.
logic/hardware/etc) failure, and not a transaction rejection.
"This logic is not necessary for memory pool transactions, as
AcceptToMemoryPool already refuses previously-known transaction ids
entirely." refers to the logic at
a206b0ea12/src/main.cpp (L484-L486),
which was later removed in commit 450cbb0944.
An IPv6 address from fc00::/8 could be either from the CJDNS network or
from a private-unroutable-reserved segment of IPv6. A seed node with
such an address must be from the CJDNS network, otherwise other peers
will not be able to connect to it.
CJDNS addresses start with constant 8 bits, so in order to account for
the first 4 random ones, we must take the first 12. Otherwise the entire
CJDNS network will belong to one group.
The default bool argument makes it harder to read because the last but
one argument is also bool. Pass all of them as named arguments to
increase readability.
Another bool argument will be added to indicate whether to test CJDNS.

In some cases addresses come from an external source as a string or as a
`struct sockaddr_in6`, without a tag to tell whether it is a private
IPv6 or a CJDNS address. In those cases interpret the address as a CJDNS
address instead of an IPv6 address if `-cjdnsreachable` is set and the
seemingly-IPv6-address belongs to `fc00::/8`. Those external sources are:
* `-externalip=`
* `-bind=`
* UPnP
* `getifaddrs(3)` (called through `-discover`)
* `addnode`
* `connect`
* incoming connections (returned by `accept(2)`)
CJDNS is set up in the host OS, outside of the application. When the
routing is configured properly then connecting to fc00::/8 results in
connecting to the CJDNS network.
Introduce an option so that Bitcoin Core knows whether this is the case.
Connecting to CJDNS addresses works without a proxy, just like
connecting to an IPv6 address. Thus adapt `CService::GetSockAddr()` to
retrieve the `struct sockaddr*` even for `CService::IsCJDNS()` objects.
AcceptToMemoryPool() is called for an invalid coinbase transaction, so
setting bypass_limits to true or false has no impact on the test.
The only way that changing bypass_limits from true to false could change
the result would be to change the outcome to INVALID(TX_MEMPOOL_POLICY).
Since the ATMP call in this test results in INVALID(TX_CONSENSUS) both
before and after this change, there is no change in behavior.
AcceptToMemoryPool() is called for transactions with fees above
minRelayTxFee and with the mempool not full, so setting bypass_limits to
true or false has no impact on the test.
The only way that changing bypass_limits from true to false could change
the result would be to change the outcome to INVALID(TX_MEMPOOL_POLICY).
Since all the ATMP calls in this test result in VALID both before and
after this change, there is no change in behavior.

6ae9f1cf96 Disable lock contention logging in checkqueue_tests (Jon Atack)
Pull request description:
This patch disables lock contention logging in the checkqueue_tests as some of these tests are designed to be heavily contested to trigger race conditions or other issues. This created very large log files when run with DEBUG_LOCKCONTENTION defined (up to v22) or with lock logging enabled by default in current master.

As defined in BIP340, a verification step should be executed after
`secp256k1_schnorrsig_sign` to ensure that a potentially corrupted
signature isn't used; using corrupted signatures could reveal
information about the private key used. This applies to ECSDA as
well.
Additionally clears schnorr signature if signing failed.

Unless `-deprecatedrpc=fees` is passed, top level
fee fields are no longer returned for mempool entries.
Add instructions to field help on how to access
deprecated fields, update help text for readability,
and include units. This is important to help
avoid any confusion as users move from deprecated
fields to the fee fields object (credit: jonatack).
This affects `getmempoolentry`, `getrawmempool`,
`getmempoolancestors`, and `getmempooldescendants`
Modify `test/functional/mempool_packages.py` and
`test/functional/rpc_fundrawtransaction.py` tests
to no longer use deprecated fields.
