57ec1c97b2 [wallet] correctly limit output group size (Suhas Daftuar)
Pull request description:
Also add a test to ensure that output groups are being limited, even if a wallet has many outputs corresponding to the same scriptPubKey (the test fails without the first commit).

All but one call to GetBlocksToMaturity is testing it relative to 0
for the purposes of determining whether the coinbase tx is immature.
In such case, the value greater than 0 implies that the tx is coinbase,
so there is no need to separately test that status.
This names the concept for easy singular use.

e3245f2e7b Removes Boost predicate.hpp dependency (251)
Pull request description:
This pull request removes the `boost/algorithm/string/predicate.hpp` dependency from the project.
To replace the the `predicate.hpp` dependency from the project the function calls to `boost::algorithm::starts_with` and `boost::algorithm::ends_with` have been replaced with respectively C++11's `std::basic_string::front` and `std::basic_string::back` function calls.
Refactors that were not required, but have been done anyways:
- The Boost function `all` was implicitly made available via the `predicate.hpp` header. Instead of including the appropriate header, function calls to `all` have been replaced with function calls to `std::all_of`.
- The `boost::algorithm::is_digit` predicate has been replaced with a custom `IsDigit` function that is locale independent and ASCII deterministic.

Pull request description:
This PR adds an optional (off by default) `-avoidpartialspends` flag, which changes coin select to use output groups rather than outputs, where each output group corresponds to all outputs with the same destination.
It is a privacy improvement, as each time you spend some output, any other output that is publicly associated with the destination (address) will also be spent at the same time, at the cost of fee increase for cases where coin select without group restriction would find a more optimal set of coins (see example below).
For regular use without address reuse, this PR should have no effect on the user experience whatsoever; it only affects users who, for some reason, have multiple outputs with the same destination (i.e. address reuse).
Nodes with this turned off will still try to avoid partial spending, if the fee of the resulting transaction is not greater than the fee of the original transaction.
Example: a node has four outputs linked to two addresses `A` and `B`:
* 1.0 btc to `A`
* 0.5 btc to `A`
* 1.0 btc to `B`
* 0.5 btc to `B`
The node sends 0.2 btc to `C`. Without `-avoidpartialspends`, the following coin selection will occur:
* 0.5 btc to `A` or `B` is picked
* 0.2 btc is output to `C`
* 0.3 - fee is output to (unique change address)
With `-avoidpartialspends`, the following will instead happen:
* Both of (0.5, 1.0) btc to `A` or `B` is picked (one or the other pair)
* 0.2 btc is output to `C`
* 1.3 - fee is output to (unique change address)
As noted, the pro here is that, assuming nobody sends to the address after you spend from it, you will only ever use one address once. The con is that the transaction becomes slightly larger in this case, because it is overpicking outputs to adhere to the no partial spending rule.
This complements #10386, in particular it addresses @luke-jr and @gmaxwell's concerns in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-300667926 and https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381.
Together with `-avoidreuse`, this fully addresses the concerns in #10065 I believe.

Because false is synonymous with TX_NONSTANDARD, this conveys the same
information and makes the handling explicitly based on script type,
simplifying each call site.
Prior to this change it was common for the return value to be ignored,
or for the return value and TX_NONSTANDARD to be redundantly handled.
This is a squashed commit that squashes the following commits:
This commit removes the `boost/algorithm/string/predicate.hpp` dependenc
from the project by replacing the function calls to `boost::algorithm::starts_with`
`boost::algorithm::ends_with` and `all` with respectively C++11'
`std::basic_string::front`, `std::basic_string::back`, `std::all_of` function calls
This commit replaces `boost::algorithm::is_digit` with a locale independent isdigi
function, because the use of the standard library's `isdigit` and `std::isdigit
functions is discoraged in the developer notes

Pull request description:
This mode ('createwallet {"disableprivatekeys": true}') is intended for a sane pure watch-only mode, ideal for a use-case where one likes to use Bitcoin-Core in conjunction with a hardware-wallet or another solutions for cold-storage.
Since we have support for custom change addresses in `fundrawtransaction`, pure watch-only wallets including coin-selection are possible and do make sense for some use cases.
This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

7223263899 wallet: Add tests for ParseHDKeypath(...) (practicalswift)
Pull request description:
Add error handling. Check return value of `ParseUInt32(...)` in `ParseHDKeypath(...)`.
`ParseUInt32(...)` returns `false` if the entire string could not be parsed or when an overflow or underflow occurred. In such case the uninitialized variable `number` would be used in the calculation of `path` (prior to this commit).
An example key path triggering this is `m/0/4294967296`:
```
ParseHDKeypath("m/0/4294967296", keypath);
```
`4294967296` is `1` + `0xFFFFFFFF` (`uint32_t` max: `4294967295`).
Introduced in a4b06fb42e which was merged into `master` 14 hours ago as part of #13557 ("BIP 174 PSBT Serializations and RPCs").

41c607f09b Implement PSBT Structures and un/serialization methods per BIP 174 (Andrew Chow)
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.

This supersedes #12136

backupwallet was broken for multiwallets in their own directories
(i.e. something like DATADIR/wallets/mywallet/wallet.dat). In this
case, the backup would use DATADIR/wallets/wallet.dat as source file
and not take the specific wallet's directory into account.
This led to either an error during the backup (if the wrong source
file was not present) or would silently back up the wrong wallet;
especially the latter behaviour can be quite bad for users.

Pull request description:
Adds an "address_type" parameter that accepts "legacy", "p2sh-segwit", and "bech32" to choose the type of address created. Defaults to "legacy" rather than the value of the `-address-type` option for backwards compatibility.
As part of implementing this, OutputType is moved from wallet into its own module, and `AddAndGetDestinationForScript` is changed to apply to a `CKeyStore` rather than a wallet, and to invoke `keystore.AddCScript(script)` itself rather than expecting the caller to have done that.

3c292cc19 ScanforWalletTransactions should mark input txns as dirty (Gregory Sanders)
Pull request description:
I'm hitting a corner case in my mainnet wallet where I load a restore a wallet, call `rescanblockchain` from RPC, and it's "double counting" an output I've sent to myself since currently it never marks input transactions as dirty. This is fixed by a restart of the wallet.
Note that this only happens with keys with birthdate *after* the blocks containing the spent funds which gets scanned on startup, so it's hard to test without a set seed function.

According to my understanding, it should not be possible for coinbase
transactions to be conflicting, thus it should not be possible for
GetDepthInMainChain to return a negative result. If it did, this would
also result in innacurate results for GetBlocksToMaturity due to the
math therein. asserting ensures accuracy.
Prior to this change, it would mark only the first layer of
child transactions abandoned, due to always following the input hashTx
rather than the current now tx.
