Merge #12220: Error if relative -walletdir is specified
ec527c6 Don't allow relative -walletdir paths (Russell Yanofsky)

Pull request description:

  This makes it an error to explicitly specify a non-absolute -walletdir path, and also adds a debug.log warning if a relative rather than absolute -datadir path is configured.

  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 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.

fa1e69e qa: Sync with validationinterface queue in sync_mempools (MarcoFalke)

Pull request description:

  Commit e545dedf72 moved `TransactionAddedToMempool` to the background scheduler thread. Thus, adding a transaction to the mempool will no longer add it to the wallet immediately. Functional tests, that `sync_mempools` and then call into wallet rpcs will race against the scheduler thread.

  Fix that race by flushing the scheduler queue.

Merge #12101: Clamp walletpassphrase timeout to 2^30 seconds and check its 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.

  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.

0b63e3c7b2 Clamp walletpassphrase timeout to 2^(30) seconds and check its bounds
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.

Merge #12150: Fix ListCoins test failure due to unset g_address_type, g_change_type
f765bb3788 Fix ListCoins test failure due to unset g_address_type, g_change_type (Russell Yanofsky)

Pull request description:

  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.

940a21932b SegWit wallet support
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`).
