5778bf95d9 Report minfeefilter value in getpeerinfo rpc (Anthony Towns)
Pull request description:
Lowering the minimum relay fee is only useful when many nodes in the p2p network also lower the fee, so to make it easier to understand progress on that front, this includes the value of the minfeefilter in getpeerinfo, so you at least have visibility to what fees your neighbours are currently accepting.

870bd4c73d Update functional RBF test to check replaceable flag (dexX7)
820d31f95f Add "bip125-replaceable" flag to mempool RPCs (dexX7)
Pull request description:
This pull request adds a flag "bip125-replaceable" to the mempool RPCs getrawmempool, getmempoolentry, getmempoolancestors and getmempooldescendants, which indicates whether an unconfirmed transaction might be replaced.
Initially the flag was added to the raw transaction RPCs, but thanks to @conscott, it was moved to the mempool RPCs, which actually have access to the mempool.
~~This pull request adds a flag "bip125-replaceable" to the RPCs "getrawtransaction" and "decoderawtransaction", which indicates, whether a transaction signals BIP 125 replaceability.~~
There was some discussion in #7817, whether showing replaceability in the UI could lead to the false assumption that transactions that don't signal BIP 125 are truely non-replaceable, but given that this PR tackles the raw transaction interface, which is a rather low level tool, I believe having this extra piece of information isn't bad.

This PR instead uses the value of the 50th percentile weight unit in the block, and also calculates the feerate at the 10th, 25th, 75th, and 90th percentiles. This more accurately corresponds with what is generally meant by median feerate.

ac8a1d092e [RPC] Remove field in getblocktemplate help that has never been used (Conor Scott)
Pull request description:
[BIP 22 - getblocktemplate](https://github.com/bitcoin/bips/blob/master/bip-0022.mediawiki#Transactions%20Object%20Format) specifies an optional flag, `required` if the transaction must be in the block.
Luke's implementation #936 did not include this flag, and it was later added to the help description in #3246 (more than a year later) but the field was still never actually implemented. As far as I can tell, bitcoin core would have never actually included this in a `getblocktemplate` call, so it seems logical to remove it from the help description.
If I am missing something or this is considered harmless - I can close the PR.

This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

Pull request description:
This Pull Request fully implements the [updated](https://github.com/bitcoin/bips/pull/694) BIP 174 specification. It is based upon #13425 which implements the majority of the signing logic.
BIP 174 specifies a binary transaction format which contains the information necessary for a signer to produce signatures for the transaction and holds the signatures for an input while the input does not have a complete set of signatures.
This PR contains structs for PSBT, serialization, and deserialzation code. Some changes to `SignatureData` have been made to support detection of UTXO type and storing public keys.
***
Many RPCs have been added to handle PSBTs.
`walletprocesspsbt` takes a PSBT format transaction, updates the PSBT with any inputs related to this wallet, signs, and finalizes the transaction. There is also an option to not sign and just update.
`walletcreatefundedpsbt` creates a PSBT from user provided data in the same form as createrawtransaction. It also funds the transaction and takes an options argument in the same form as `fundrawtransaction`. The resulting PSBT is blank with no input or output data filled in. It is analogous to a combination of `createrawtransaction` and `fundrawtransaction`
`decodepsbt` takes a PSBT and decodes it to JSON. It is analogous to `decoderawtransaction`
`combinepsbt` takes multiple PSBTs for the same tx and combines them. It is analogous to `combinerawtransaction`
`finalizepsbt` takes a PSBT and finalizes the inputs. If all inputs are final, it extracts the network serialized transaction and returns that instead of a PSBT unless instructed otherwise.
`createpsbt` is like `createrawtransaction` but for PSBTs instead of raw transactions.
`convertpsbt` takes a network serialized transaction and converts it into a psbt. The resulting psbt will lose all signature data and an explicit flag must be set to allow transactions with signature data to be converted.

Alternative to #9152.
This takes `<n>` pubkeys and optionally `<n>` xpubs (together with a definable lookup windows where the default is 0-1000) and looks up common scripts in the UTXO set of all given or derived keys.
The output will be an array similar to `listunspent`. That array is compatible with `createrawtransaction` as well as with `signrawtransaction`.
This makes it possible to prepare sweeps and have them signed in a secure (cold) space.

Pull request description:
Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/
This change would at least allow `verifytxoutproof` to properly validate that the proof matches a known block, with known number of transactions any time after the full block is processed. This should neuter the attack entirely.
The negative is that a header-only processed block/future syncing mode would cause this to fail until the node has imported the data required.

0422beb9b Make SignatureData able to store signatures and scripts (Andrew Chow)
b6edb4f5e Inline Sign1 and SignN (Andrew Chow)
Pull request description:
Currently CombineSignatures is used to create the final scriptSig or an input. However ProduceSignature is capable of doing this itself. Using both CombineSignatures and ProduceSignature results in code duplication which is unnecessary.
To move the scriptSig construction to ProduceSignatures, the SignatureData class contains two maps to hold pubkeys mapped to signatures, and script ids mapped to scripts. DataFromTransaction is extended to be able to extract signatures, their public keys, and scripts from existing ScriptSigs.
The SignaureData are then passed down to SignStep which can use the aforementioned maps to get the signatures, pubkeys, and scripts that it needs, falling back to the actual SigningProvider and SignatureCreator if the data are not available in the SignatureData.
Additionally, Sign1 and SignN have been removed and their functionality inlined into SignStep since Sign1 is really just a wrapper around CreateSig.
Since ProduceSignature can produce the final scriptSig or scriptWitness by using SignatureData which has extracted data from the transaction, CombineSignatures is unnecessary as ProduceSignature is able to replicate all of CombineSignatures' functionality.
This also furthers BIP 174 support and begins moving towards a BIP 174 style backend.
The tests have also been updated to use the new combining methodology.

This PR takes a different approach, and removes the `isInvalid` entirely. It was only ever used inside tests, as normal users of IsMine don't care about the reason for non-mine-ness, only whether it is or not. As the unit tests are extensive enough, it seems sufficient to have a black box text (with tests for both compressed and uncompressed keys).

Instead of using CombineSignatures to create the final scriptSig or
scriptWitness of an input, use ProduceSignature itself.
To allow for ProduceSignature to place signatures, pubkeys, and scripts
that it does not know about, we pass down the SignatureData to SignStep
which pulls out the information that it needs from the SignatureData.
In addition to having the scriptSig and scriptWitness, have SignatureData
also be able to store just the signatures (pubkeys mapped to sigs) and
scripts (script ids mapped to scripts).
Also have DataFromTransaction be able to extract signatures and scripts
from the scriptSig and scriptWitness of an input to put them in SignatureData.
Adds a new SignatureChecker which takes a SignatureData and puts pubkeys
and signatures into it when it successfully verifies a signature.
Adds a new field in SignatureData which stores whether the SignatureData
was complete. This allows us to also update the scriptSig and
scriptWitness to the final one when updating a SignatureData with another
one.
Signatures using segregated witness commit to the amount being spent,
so that value must be passed into signrawtransactionwithkey and
signrawtransactionwithwallet. This ensures an error is issued if that
doesn't happen, rather than just assuming the value is 0 and producing
a signature that is almost certainly invalid.
