Pull request description:

  Transaction relay is optimized for a combination of redundancy/robustness as well as bandwidth minimization -- as a result transaction relay leaks information that adversaries can use to infer the network topology.

  Network topology is better kept private for (at least) two reasons:

  (a) Knowledge of the network graph can make it easier to find the source IP of a given transaction.

  (b) Knowledge of the network graph could be used to split a target node or nodes from the honest network (eg by knowing which peers to attack in order to achieve a network split).

  We can eliminate the risks of (b) by separating block relay from transaction relay; inferring network connectivity from the relay of blocks/block headers is much more expensive for an adversary.

  After this commit, bitcoind will make 2 additional outbound connections that are only used for block relay. (In the future, we might consider rotating our transaction-relay peers to help limit the effects of (a).)

bc6d8a3662 gui: Refactor OpenWalletActivity (João Barbosa)

Pull request description:

  This PR adds a menu option to create a new wallet. When clicked, a `CreateWalletDialog` will be created and prompt the user to name the wallet and choose whether to disable private keys, make a blank wallet, and encrypt the wallet. If the wallet is encrypted, the wallet will be born encrypted with the wallet first created blank, then encrypted, and then a new HD seed generated and set.

  To allow the newly created wallets to be encrypted, some changes to how encrypting a wallet works. Instead of encrypting and locking the wallet, the wallet will be encrypted and then unlocked. This is also an extra belt-and-suspenders check to make sure that encryption worked.

Merge #16421: Conservatively accept RBF bumps bumping one tx at the package limits
5ce822efbe Conservatively accept RBF bumps bumping one tx at the package limits (Matt Corallo)

Pull request description:

  Based on #15681, this adds support for some simple cases of RBF inside of large packages. Issue pointed out by sdaftuar in #15681, and this fix (or a broader one) is required ot make #15681 fully useful.

  Accept RBF bumps of single transactions (ie which evict exactly one
  transaction) even when that transaction is a member of a package
  which is currently at the package limit iff the new transaction
  does not add any additional mempool dependencies from the original.

  This could be made a bit looser in the future and still be safe,
  but for now this fixes the case that a transaction which was
  accepted by the carve-out rule will not be directly RBF'able

Merge #16798: Refactor rawtransaction_util's SignTransaction to separate prevtx parsing
39034f1ee6 Refactor rawtransaction_util's SignTransaction to have previous tx parsing be separate (Andrew Chow)

Pull request description:

  Currently the `SignTransaction` function has to handle both the actual signing and parsing of previous transaction data. This PR splits it so that `SignTransaction` only handles the signing itself and adds a `ParsePrevouts` function which handles parsing the prevtx information.

  This allows for `SignTransaction` to just take any `SigningProvider`.

Merge #16624: wallet: encapsulate transactions state
442a87cc0a Add a test wallet_reorgsrestore (Antoine Riard)
40ede992d9 Modify wallet tx status if has been reorged out (Antoine Riard)
7e89994133 Remove SyncTransaction for conflicted txn in CWallet::BlockConnected (Antoine Riard)
a31be09bfd Encapsulate tx status in a Confirmation struct (Antoine Riard)

Pull request description:

  While working on #15931, I've tried to rationalize tx state management to ease integration of block height tracking per-wallet tx. We currently rely on a combination of `hashBlock` and `nIndex` with magic value to determine tx confirmation, conflicted or abandoned state. It's hard to reason and error-prone.  To solve that, we encapsulate these fields in a `TxConfirmation` struct and introduce a `TxState` member that we update accordingly at block connection/disconnection.

  Following jnewbery [recommendation](https://github.com/bitcoin/bitcoin/pull/15931#discussion_r312576506), I've taken these changes in its own commit, and open a PR to get them first. It would ease review of aforementioned PR, but above all should ease fixing of long-term issues like :
  * https://github.com/bitcoin/bitcoin/issues/7315 (but maybe we should abandon abandontransaction or relieve it to only free outpoints not track the transaction as abandoned in itself, need its own discussion)
  * https://github.com/bitcoin/bitcoin/issues/8692 where we should cancel conflicted state of transactions chain smoothly
  * `MarkConflicted` in `LoadToWallet` is likely useless if we track conflicts rights at block connection

  Main changes of this PR to get right are tx update in `AddToWallet` and serialization/deserialization logic.

Merge #16792: Assert that the HRP is lowercase in Bech32::Encode
2457aea83c Assert that the HRP is lowercase in Bech32::Encode (Samuel Dobson)

Pull request description:

  From BIP-173:
  > The lowercase form is used when determining a character's value for checksum purposes.
  > Encoders MUST always output an all lowercase Bech32 string. If an uppercase version of the encoding result is desired, (e.g.- for presentation purposes, or QR code use), then an uppercasing procedure can be performed external to the encoding process.

  Currently if HRP contains uppercase characters, the checksum will be generated over these uppercase characters resulting in mixed-case output that will always be invalid even if the case is changed manually after encoding. This shouldn't happen because both prefix's `bc` and `tb` are lowercase currently, but we assert this condition anyway.

  This is consistent also with the [C reference implementation](2b0aac650c/ref/c/segwit_addr.c (L59))

Transaction relay is primarily optimized for balancing redundancy/robustness
with bandwidth minimization -- as a result transaction relay leaks information
that adversaries can use to infer the network topology.

Network topology is better kept private for (at least) two reasons:

(a) Knowledge of the network graph can make it easier to find the source IP of

(b) Knowledge of the network graph could be used to split a target node or
nodes from the honest network (eg by knowing which peers to attack in order to

We can eliminate the risks of (b) by separating block relay from transaction
relay; inferring network connectivity from the relay of blocks/block headers is
much more expensive for an adversary.

After this commit, bitcoind will make 2 additional outbound connections that
are only used for block relay. (In the future, we might consider rotating our
transaction-relay peers to help limit the effects of (a).)

  Fixes #16773

  I'm not entirely sure why 16773 happend, but probably due to headers fallback in a compact block.

  However, this PR should fix it and should have been included in #15615.

    utACK dcc448e3d2. Went and read how pindexBestHeader is handled and this code looks correct (worst case it breaks a LogPrint, so whatever). I also ran into this on #16762.

In the words of MarcoFalke:
"W504 should be disabled. This is not a critical error that should be blocking a merge"

Pull request description:

  The translations are going to close in three days (#15940), so I am submitting this as a standalone pull request.

  Those changes are part of a bugfix #16661, which includes a test. The first change (the refactor) is required, the second commit is not. I am happy to drop it, if needed.
