16f6f59dc [qa] Test fundrawtransaction with change_type option (João Barbosa)
536ddeb17 [rpc] Add change_type option to fundrawtransaction (João Barbosa)
31dbd5af4 [wallet] Add change type to CCoinControl (João Barbosa)
Pull request description:
Adds a new option `change_type` to `fundrawtransaction` RPC. This is useful to override the node `-changetype` argument.
The new option is exclusive to `changeAddress` option, setting both raises a RPC error.
See also #11403, #12119.

f523c6bec [qa] Use address type in addmultisigaddress to avoid addwitnessaddress (João Barbosa)
886a92f25 [rpc] Add address type option to addmultisigaddress (João Barbosa)
Pull request description:
Adds the option `address_type` to `addmultisigaddress` and `createmultisg` RPC. This also allows to avoid `addwitnessaddress` to obtain an `p2sh-segwit` or `bech32` multsig address.
Related to #12210 as this reduces `addwitnessaddress` usage.

or P2WSH
596c446 [wallet] use P2WPKH change output if any destination is P2WPKH or P2WSH (Sjors Provoost)
Pull request description:
If `-changetype` is not explicitly set, then regardless of `-addresstype`, the wallet will use a ~`bech32` change address~ `P2WPKH` change output if any destination is `P2WPKH` or `P2WSH`.
This seems more intuitive to me and more in line with the spirit of [BIP-69](https://github.com/bitcoin/bips/blob/master/bip-0069.mediawiki).
When combined with #11991 a QT user could opt to use `bech32` exclusively without having to figure out how to launch with `-changetype=bech32`, although so would #11937.

1df206f Disallow using addresses in createmultisig (Andrew Chow)
Pull request description:
This PR should be the last part of #7965.
This PR makes createmultisig only accept public keys and marks the old functionality of accepting addresses as deprecated.
It also splits `_createmultisig_redeemscript` into two functions, `_createmultisig_getpubkeys` and `_createmultisig_getaddr_pubkeys`. `_createmultisig_getpubkeys` retrieves public keys from the RPC parameters and `_createmultisig_getaddr_pubkeys` retrieves addresses' public keys from the wallet. `_createmultisig_getaddr_pubkeys` requires the wallet and is only used by `addwitnessaddress` (except when `createmultisig` is used in deprecated mode).
`addwitnessaddress`'s API is also changed. Instead of returning just an address, it now returns the same thing as `createmultisig`: a JSON object with two fields, address and redeemscript.

Pull request description:

This was probably only done because of laziness and it is an important show-stopper for #11200 (GUI rescan abort).

Also warn if bitcoind is configured to use a relative -datadir path.
Specifying paths relative to the current working directory in a daemon process
can be dangerous, because files can fail to be located even if the
configuration doesn't change, but the daemon is started up differently.
Specifying a relative -datadir now adds a warning to the debug log. It would
not be backwards-compatible to forbid relative -datadir paths entirely, and it
could also be also inconvenient for command line testing.
Specifying a relative -walletdir now results in a startup error. But since the
-walletdir option is new in 0.16.0, there should be no compatibility issues.
Another reason not to use working directory paths for -walletdir specifically
is that the default -walletdir is a "wallets" subdirectory inside the datadir,
so it could be surprising that setting -walletdir manually would choose a
directory rooted in a completely different location.

Now that segwit is natively supported by the wallet, deprecate the hack `addwitnessaddress`.

bounds
134cdc7 Test walletpassphrase timeout bounds and clamping (Andrew Chow)
0b63e3c Clamp walletpassphrase timeout to 2^(30) seconds and check its bounds (Andrew Chow)
Pull request description:
Fixes #12100
Makes the timeout be clamped to 2^30 seconds to avoid the issue with sign flipping with large timeout values and thus relocking the wallet instantly. Unlocking for at most ~34 years should be sufficient.
Also checks that the timeout is not negative to avoid instant relocks.

63ac8907c [qt] receive tab: bech32 address opt-in checkbox (Sjors Provoost)

Checkbox does what you would expect. Press tab from the amount field to get there.
It's unchecked by default.
When launched with `-addresstype=bech32` it's checked by default. When launched with `-addresstype=legacy` it unchecked and disabled.
The change in `receivecoinsdialog.ui` is smaller than it looks, due to the way git handles XML diffs. I had to add a horizontal spacer to make it look decent, see https://github.com/bitcoin/bitcoin/issues/11950#issuecomment-352870909. This causes column numbers to change in the rest of the grid.
I recommend testing on at least one other OS than OSX to be on the safe side.

Clamps the timeout of walletpassphrase to 2^(30) seconds, which is
~34 years. Any number greater than that will be forced to be
2^(30). This avoids the sign flipping problem with large values which
can result in a negative time used.
Also perform bounds checks to ensure that the timeout is positive
to avoid immediate relocking of the wallet.

Make createmultisig only accept public keys with the old functionality
marked as deprecated.
Splits _createmultisig_redeemscript into two functions, one for
getting public keys from UniValue and one for getting addresses
from UniValue and then their respective public keys. The one for
retrieving address's public keys is located in rpcwallet.cpp
Changes addwitnessaddress's output to be a JSON object with
two fields, address and redeemscript.
Adds a test to deprecated_rpc.py for testing the deprecation.
Update the tests to use addwitnessaddress or give only public keys
to createmultisig. Anything that used addwitnessaddress was also
updated to reflect the new API.

New global variables were introduced in #11403 and not setting them causes:
test_bitcoin: wallet/wallet.cpp:4199: CTxDestination GetDestinationForKey(const CPubKey&, OutputType): Assertion `false' failed.
unknown location(0): fatal error in "ListCoins": signal: SIGABRT (application abort requested)
It's possible to reproduce the failure reliably by running:
src/test/test_bitcoin --log_level=test_suite --run_test=wallet_tests/ListCoins
Failures happen nondeterministically because boost test framework doesn't run
tests in a specified order, and tests that run previously can set the global
variables and mask the bug.

Pull request description:
This implements a minimum viable implementation of SegWit wallet support, based on top of #11389, and includes part of the functionality from #11089.
Two new configuration options are added:
* `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`.
* `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used.
All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version.
The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key.
To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used:
* All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date.
* All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
* All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work.
These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented.
`dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.

This introduces two command line flags (-addresstype and -changetype) which control
the type of addresses/outputs created by the GUI and RPCs. Certain RPCs allow
overriding these (`getnewaddress` and `getrawchangeaddress`). Supported types
are "legacy" (P2PKH and P2SH-multisig), "p2sh-segwit" (P2SH-P2WPKH and P2SH-P2WSH-multisig),
and "bech32" (P2WPKH and P2WSH-multisig).
A few utility functions are added to the wallet to construct different address type
and to add the necessary entries to the wallet file to be compatible with earlier
versions (see `CWallet::LearnRelatedScripts`, `GetDestinationForKey`,
`GetAllDestinationsForKey`, `CWallet::AddAndGetDestinationForScript`).

5cbbbd7 [Wallet] Use RBF by default in QT only (Sjors Provoost)
Pull request description:
~If there are no objections, this would supersede #11556.~
Enabling RBF by default avoids the need to explain all possible use cases of RBF.
This PR does not change the default RPC wallet behavior, as this could break implementations that depend on it and it's not clear what happens when automated services suddenly switch on RBF on a large scale.
After trying various approaches, we settled on just having QT ignore `-walletrbf`.

GUI wallet uses RBF by default, regardless of -walletrbf.
RPC and debug console in the GUI remain unchanged; they don't
use RBF by default, unless launched with -walletrbf=1.

Pull request description:
As discussed in https://github.com/bitcoin/bitcoin/pull/11289#issuecomment-334600457, adds the CScripts from the wallet to the `dumpwallet` RPC and then allows them to be imported with the `importwallet` RPC. Includes a basic test, and modifies the helptext of the dumpwallet RPC.
Notes:
- Reviewers: use `?w=1` to avoid the indentation-only change in commit `Add scripts to importwallet RPC `
- currently the scripts are followed with `# addr=` comments just as the other keys are, unsure if this might confuse users into thinking all the scripts are for valid P2SH addresses though, but I don't think that should be an issue.
- there are no birthtimes for scripts, so script imports don't affect rescans
- `importwallet` imports the CScripts but I'm not sure how to approach specifying whether scripts are for P2SH addresses, BIP173 addresses, etc. whether that matters or not. Otherwise the RPC helptext might just need modification.
Fixes #11715
