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`).

This requires the removal of some very liberal (incorrect) cs_mains
sprinkled in some tests. It adds some chainActive.Tip() races, but
the tests are all single-threaded anyway.
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.

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.

ecf9b25 remove unused fNoncriticalErrors variable from CWalletDB::FindWalletTx (Pierre Rochard)
Pull request description:
The `CWalletDB::FindWalletTx` method was patterned after `CWalletDB::LoadWallet`, where `fNoncriticalErrors` is used when a tx check fails in `ReadKeyValue`.
Since `FindWalletTx` is only used by methods which are zapping txs, it makes sense that `ReadKeyValue` is not called and the tx is not checked, so I think that deleting the unused `fNoncriticalErrors` boolean variable and its conditional statement is appropriate.

Pull request description:
Closes#11348
Adds a `-walletdir` parameter which specifies a directory to use for wallets, allowing them to be stored separately from the 'main' data directory. Creates a new `wallets/` directory in datadir if this is the first time running, and defaults to using it if it exists.
Includes tests and release notes. Things which might need to be considered more:
- there is no 'lock' on the wallets directory, which might be needed?
- because this uses a new wallets/ directory by default, downgrading to an earlier version won't see the wallets in that directory (not a big deal though, users can just copy them up to the main dir)
- jnewbery suggested putting each wallet in its own directory, which is a good idea, but out of scope for this PR IMO. EDIT: this is being done in https://github.com/bitcoin/bitcoin/pull/11687
- doc/files.md needs updating (will do soon)
I also considered including a cleanup by removing caching of data directory paths and instead just initialise them once on startup (c.f. #3073), but decided it wasn't super relevant here will just complicate review.

Pull request description:
Make feebumper methods static and remove stored state in the class.
Having the results of feebumper calls persist in an object makes process
separation between Qt and wallet awkward, because it means the feebumper object
either has to be serialized back and forth between Qt and wallet processes
between fee bump calls, or that the feebumper object needs to stay alive in the
wallet process with an object reference passed back to Qt. It's simpler just to
have fee bumper calls return their results immediately instead of storing them
in an object with an extended lifetime.
In addition to making feebumper methods static, also:
- Move LOCK calls from Qt code to feebumper
- Move TransactionCanBeBumped implementation from Qt code to feebumper
- Rename CFeeBumper class to FeeBumper (every CFeeBumper reference had to be
updated in this PR anyway so this doesn't increase the size of the diff)

Change feebumper from a stateful class into a namespace of stateless
functions.
Having the results of feebumper calls persist in an object makes process
separation between Qt and wallet awkward, because it means the feebumper object
either has to be serialized back and forth between Qt and wallet processes
between fee bump calls, or that the feebumper object needs to stay alive in the
wallet process with an object reference passed back to Qt. It's simpler just to
have fee bumper calls return their results immediately instead of storing them
in an object with an extended lifetime.
In addition to making feebumper stateless, also:
- Move LOCK calls from Qt code to feebumper
- Move TransactionCanBeBumped implementation from Qt code to feebumper
Future commit will remove the FeeBumper class. This commit simply places
everything into a feebumper namespace, and changes the enum class name
from BumpeFeeResult to feebumper::Result.
Future PRs will completely refactor this translation unit and touch all
this code so we rename the variables to follow project stlye guidelines
in this preparation commit.
Don't use m_ prefixes for member variables since we're going to remove
the class entirely in the next commits.

5a5e4e9 [wallet] Remove CTransaction&() helper conversion operator from wallet implementation. (Karl-Johan Alm)
Pull request description:
The `CTransaction&()` operator in `CMerkleTx` makes conversion into `CTransaction`s transparent, but was marked as to-be-removed in favor of explicitly getting the `tx` ivar, presumably as the operator can lead to ambiguous behavior and makes the code harder to follow.
This PR removes the operator and adapts callers. This includes some cases of `static_cast<CTransaction>(wtx)` → `*wtx.tx`, which is definitely an improvement.

WalletParameterInteraction: parameter interaction: -disablewallet -> ignoring -wallet=bar

It also moves up the `-disablewallet` check which avoids the unnecessary `-wallet` soft set.
The second commit fixes the default value of `-disablewallet`, currently the value is correct, but it should use `DEFAULT_DISABLE_WALLET`.
The third commit can be dropped or squashed, just took the opportunity to fix the coding style there.

720d9e8fa [Wallet] always show help-line of wallet encryption calls (Jonas Schnelli)
Pull request description:
We do currently show/hide the wallet encryption RPC calls from the help if the current wallet.
In case of an encrypted wallet, `encryptwallet` is hidden and `walletpassphrasechange`, `walletpassphrasechange` and `walletlock` do appear in the help.
This is no longer ideal in case of multiwallet due to the fact that one may want help infos in order to target a specific wallet.
IMO its preferable to have a static help screen (show everything always). The currently show/hidden calls do handle the possible invalid encryption-state fine.

Change suggested by Cory Fields <cory-nospam-@coryfields.com> who noticed
listsinceblock would ignore invalid block hashes causing it to return a
completely unfiltered list of transactions.
Make sure wallet databases have unique fileids. If they don't, throw an error.
BDB caches do not work properly when more than one open database has the same
fileid, because values written to one database may show up in reads to other
databases.
Bitcoin will never create different databases with the same fileid, but users
can create them by manually copying database files.
BDB caching bug was reported by Chris Moore <dooglus@gmail.com>

7104de8 [wallet] Fix leak in CDB constructor (João Barbosa)
Pull request description:
First commit fixes a minor leak.
Second commit improves the constructor in the failure cases.

Now using a std::unique_ptr, the Db instance is correctly released
when CDB initialization fails.
The internal CDB state and mapFileUseCount are only mutated when
the CDB initialization succeeds.
This avoid calling out to mempool state during coin selection,
balance calculation, etc. In the next commit we ensure all wallet
callbacks from CValidationInterface happen in the same queue,
serialized with each other. This helps to avoid re-introducing one
of the issues described in #9584 [1] by further disconnecting
wallet from current chain/mempool state.
Thanks to @morcos for the suggestion to do this.
Note that there are several race conditions introduced here:
* If a user calls sendrawtransaction from RPC, adding a
transaction which is "trusted" (ie from them) and pays them
change, it may not be immediately used by coin selection until
the notification callbacks finish running. No such race is
introduced in normal transaction-sending RPCs as this case is
explicitly handled.
* Until Block{Connected,Disconnected} and
TransactionAddedToMempool calls also run in the CSceduler
background thread, there is a race where
TransactionAddedToMempool might be called after a
Block{Connected,Disconnected} call happens.
* Wallet will write a new best chain from the SetBestChain
callback prior to having processed the transaction from that
block.
[1] "you could go to select coins, need to use 0-conf change, but
such 0-conf change may have been included in a block who's
callbacks have not yet been processed - resulting in thinking they
are not in mempool and, thus, not selectable."
This prevents the wallet-RPCs-return-stale-info issue from being
re-introduced when new-block callbacks no longer happen in the
block-connection cs_main lock

Pull request description:
Document assumptions (via `assert(…)`:s) that are being made to avoid division by zero.
Rationale:
* Make it clear to human reviewers and non-human static analyzers that what might look like potential division by zero cases are written the way they are intentionally (these cases are currently flagged by various static analyzers).
