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.

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))

fae91a09c4 test: Remove incorrect and unused try-block in assert_debug_log (MarcoFalke)
Pull request description:
This try block has accidentally been added by me in fa3e9f7627.
It was unused all the time, but commit 6011c9d72d added a `return` in the finally block, muting all exceptions.

This is a second go at #15221, fixing new lints in:
W504 line break after binary operator
W605 invalid escape sequence
F841 local variable 'e' is assigned to but never used
This time around:
* One commit per rule, for easier review
* I went with the PEP-8 style of breaking before binary operators
* I looked into the raw regex newline issue, and found that raw strings with newlines embedded do work appropriately. E.g. run `re.match(r" \n ", " \n ")` to check this for yourself. `re.MULTILINE` exists to modify `^` and `$` in multiline scenarios, but all of these searches are per-line.

Accept RBF bumps of single transactions (ie which conflict with 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.
If we set fRelay=false in our VERSION message, and a peer sends an INV or TX
message anyway, disconnect. Since we use fRelay=false to minimize bandwidth,
we should not tolerate remaining connected to a peer violating the protocol.
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
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).)

798a589aff wallet: extract PubKey from P2PK script with Solver (Sebastian Falbesoner)
Pull request description:
The function `ExtractPubKey()` checks if a given script matches the P2PK pattern
(`<PubKey> OP_CHECKSIG`), extracts the PubKey and additionally checks if it is
cryptographically valid (full validation with ECC library via `CPubKey::IsFullyValid()`).
Currently this is done manually in the following order:
1. check if first script OP is data push with valid PubKey length (first part of pattern match), extract PubKey
2. create `CPubKey` object with extracted PubKey
3. fully validate public key
4. check if last script OP is `OP_CHECKSIG` (second part of pattern match)
Using Solver, the pattern matching and PubKey extraction can be done via a
single step, leading to the following simplified order with shorter code:
1. check if given script matches P2PK pattern with Solver (also contains valid PubKey length check), extracts Pubkey
2. create `CPubKey` object with extracted Pubkey
3. fully validate public key

fa0b910486 [doc] chain: Declare BLOCK_VALID_HEADER reserved (MarcoFalke)
Pull request description:
`BLOCK_VALID_HEADER` was never used and the comment is confusing to me in several ways:
* It claims "version ok". However, without the previous header, it is not possible to check the validity of the version since the height needs to be known (c.f. BIP 90)
* It claims "hash satisfies claimed PoW". While it is possible to check against the claimed PoW, it is not possible without the previous header to check that the claimed PoW is itself valid.
* It claims "1 <= vtx count <= max". However, with the header alone and current consensus rules, the number of transactions is unknown.
