Maximum number of transactions allowed in a package is 25, equal to the
default mempool descendant limit: if a package has more transactions
than this, either it would fail default mempool descendant limit or the
transactions don't all have a dependency relationship (but then they
shouldn't be in a package together). Same rationale for 101KvB virtual
size package limit.
Note that these policies are only used in test accepts so far.
This allows us to easily create transaction chains for package
validation. We don't test_accept if submit=false because we want to be
able to make transactions that wouldn't pass ATMP (i.e. a child
transaction in a package would fail due to missing inputs).
Only allow test accepts for now. Use the CoinsViewTemporary to keep
track of coins created by each transaction so that subsequent
transactions can spend them. Uncache all coins since we only
ever do test accepts (Note this is different from ATMP which doesn't
uncache for valid test_accepts) to minimize impact on the coins cache.
Require that the input txns have no conflicts and be ordered
topologically. This commit isn't able to detect unsorted packages.
Define the Package type as an alias for a vector of transactions for now.
Add PackageValidationResult, similar to TxValidationResult and
BlockValidationResult for package-wide errors that cannot be reported
within a single transaction result, such as having too many
transactions in the package. We can update the concept of
what a package is and have different logic for packages vs lists of
transactions in the future, e.g. for package relay.
Allow CheckSequenceLocks to use heights and coins from any CoinsView and
CBlockIndex provided. This means that CheckSequenceLocks() doesn't need
to hold the mempool lock or cs_main. The caller is responsible for
ensuring the CoinsView and CBlockIndex are consistent before passing
them in. The typical usage is still to create a CCoinsViewMemPool from
the mempool and grab the CBlockIndex from the chainstate tip.

a2e122f0fe qt: Add GUIUtil::AddButtonShortcut (Hennadii Stepanov)
4ee9ee7236 qt: Use native presentation of shortcut (Hennadii Stepanov)
Pull request description:
On `master` the only way to resize the console font is to manually move your mouse and click the resize buttons. This PR introduces convenient keyboard shortcuts to resize the console font.
The common resize shortcuts for applications are `Ctrl+=`/`Ctrl++` and `Ctrl+-`/`Ctrl+_`. This means that the resize QPushButtons need two shortcuts each, but you cannot assign multiple shortcuts to a QPushButton. See: https://doc.qt.io/qt-5/qabstractbutton.html#shortcut-prop
To get around this, we introduce a new function in `guiutil`, which connects a supplied `QKeySequence` shortcut to a `QAbstractButton`. This function can be reused in other situations where more than one shortcut is needed for a button.

Pull request description:
This is a followup for https://github.com/bitcoin/bitcoin/pull/20365#discussion_r522265003
First part of a refactoring with overall goal to simplify `CWallet` and de-duplicate code with `wallettool`
**Rationale**: split `CWallet::Create` and create `CWallet::AttachChain`.
`CWallet::AttachChain` takes chain as first parameter on purpose. In future I suggest we can remove `chain` from `CWallet` constructor.
The second commit is based on be164f9cf89b123f03b926aa980996919924ee64 from #15719 (thanks ryanofsky)

Pull request description:
This refactoring PR deduplicates repeated SQLite access to PRAGMA settings. Two functions `ReadPragmaInteger(...)` (reads a single integer value via statement `PRAGMA key`) and `SetPragma(...)` (sets a key to specified value via statement `PRAGMA key = value`) are introduced for this purpose.
This should be more readable and less error-prone, e.g. in case other PRAGMA settings need to be read/set in the future or the error handling has to be adapted.

Pull request description:
While reviewing #20196, I noticed the `NetPermissionFlags` enums are frequently called as if they were scoped, yet are still global. This patch upgrades `NetPermissionFlags` to a scoped class enum and updates the enumerator naming, similarly to #19771. See https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#enum-enumerations for more info.
This change would eliminate the class of bugs like https://github.com/bitcoin/bitcoin/pull/20196#discussion_r610770148 and #21644, as only defined operations on the flags would compile.

74bf850ac4 faster HexStr => 13% faster blockToJSON (Martin Ankerl)
Pull request description:
`std::string`'s push_back is rather slow because it needs to check & update the string size. For
`HexStr` the output string size is already easily know, so we can initially create the string with
the correct size and then just assign the data.
`HexStr` is heavily usd in `blockToJSON`, so this change is a noticeable benefit. Benchmark on an i7-8700 @3.2GHz:
* 71,315,461.00 ns/op master
* 62,842,490.00 ns/op this commit
So this little change makes `blockToJSON` about ~13% faster.

This commit does not change behavior, it just moves code from
CWallet::CreateWalletFromFile to CWallet:::AttachChain so it can be updated in
the next commit.
This commit is most easily reviewed with
"git diff -w --color-moved=dimmed_zebra" or by diffing CWallet:::AttachChain
against the previous code with an external diff tool.
If a scope id is provided, return it back in the string representation.
Also bring back the test. Closes#21982.

105941b726 net: use stronger AddLocal() for our I2P address (Vasil Dimov)
Pull request description:
There are two issues:
### 1. Our I2P address not added to local addresses.
* `externalip=` is used with an IPv4 address (this sets automatically `discover=0`)
* No `discover=1` is used
* `i2psam=` is used
* No `externalip=` is used for our I2P address
* `listenonion=1 torcontrol=` are used
In this case `AddLocal(LOCAL_MANUAL)` [is used](94f83534e4/src/torcontrol.cpp (L354)) for our `.onion` address and `AddLocal(LOCAL_BIND)` [for our](94f83534e4/src/net.cpp (L2247)) `.b32.i2p` address, the latter being [ignored](94f83534e4/src/net.cpp (L232-L233)) due to `discover=0`.
### 2. Our I2P address removed from local addresses even if specified with `externalip=` on I2P proxy restart.
* `externalip=` is used with our I2P address (this sets automatically `discover=0`)
* No `discover=1` is used
* `i2psam=` is used
In this case, initially `externalip=` causes our I2P address to be [added](94f83534e4/src/init.cpp (L1266)) with `AddLocal(LOCAL_MANUAL)` which overrides `discover=0` and works as expected. However, if later the I2P proxy is shut down [we do](94f83534e4/src/net.cpp (L2234)) `RemoveLocal()` in order to stop advertising our I2P address (since we have lost I2P connectivity). When the I2P proxy is started and we reconnect to it, restoring the I2P connectivity, [we do](94f83534e4/src/net.cpp (L2247)) `AddLocal(LOCAL_BIND)` which does nothing due to `discover=0`.
To resolve those two issues, use `AddLocal(LOCAL_MANUAL)` for I2P which is also what we do with Tor.

An easy way to reproduce the bug and test this PR is to pass the `-walletdir=D:\` command-line option, and run the `listwalletdir` RPC, or File -> Open Wallet in the GUI menu.
