Pull request description:
Main commit `gui: Avoid wallet tryGetBalances calls` is one-line change to `WalletModel::pollBalanceChanged` that returns early if there hasn't been a new `TransactionChanged` or `BlockTip` notification since the previous poll call. This is the same behavior that was implemented in #18160, now implemented in a simpler way.
The other commits are a straight revert of #18160, and two tweaks to avoid relying on `WalletModel::m_client_model` lifetime which were causing travis failures with earlier versions of this PR.
Motivation for this change is to be able to revert #18160 and cut down on unnecessary cross-process calls that happen when #18160 is combined with #10102
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).

This reverts commit 0933a37078e1ce3a3d70983c3e7f4b3ac6c3fa37 from
https://github.com/bitcoin/bitcoin/pull/18160 which no longer an optimization
since commit "gui: Avoid wallet tryGetBalances calls before TransactionChanged
or BlockTip notifications".
This change is intended to make the bitcoin node and its rpc, network
and gui interfaces more responsive while the wallet is in use. Currently
because the node's cs_main mutex is always locked before the wallet's
cs_wallet mutex (to prevent deadlocks), cs_main currently stays locked
while the wallet does relatively slow things like creating and listing
transactions.
This commit only remmove chain lock tacking in wallet code, and invert
lock order from cs_main, cs_wallet to cs_wallet, cs_main.
must happen at once to avoid any deadlock. Previous commit were only
removing Chain::Lock methods to Chain interface and enforcing they
take cs_main.
Remove LockChain method from CWallet and Chain::Lock interface.

Previous versions assumed absence of an entry in mapAddressBook indicated change.
This no longer holds true (due to bugs) and will shortly be made intentional.
Renaming the field helps ensure that old code using mapAddressBook directly gets checked for necessary rebasing.
-BEGIN VERIFY SCRIPT-
sed -i -e 's/mapAddressBook/m_address_book/g' $(git grep -l 'mapAddressBook' ./src)
-END VERIFY SCRIPT-
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
It also helps ensure the GUI display stays up to date in the case where the
node chain height runs ahead of wallet last block processed height.
0933a37078e1ce3a3d70983c3e7f4b3ac6c3fa37 gui: Avoid Wallet::GetBalance in WalletModel::pollBalanceChanged (João Barbosa)
Pull request description:
Each 250ms the slot `WalletModel::pollBalanceChanged` is called which, at worst case, calls `Wallet::GetBalance`. This is a waste of resources since most of the time there aren't new transactions or new blocks. Fix this by early checking if cache is dirty or not.
The actual balance computation can still hang the GUI thread but that is tracked in #16874 and should be fixed with a solution similar to #17135.

Replace by privateKeysDisabled method to avoid need for GUI to reference
internal wallet flags.
Also remove adjacent WalletModel canGetAddresses wrapper that serves no purpose
and make Wallet::canGetAddresses non-const so it can be implemented by IPC
classes in #10102.
Not all ScriptPubKeyMans will be able to provide private keys,
but pubkeys and scripts should be. So only provide public-only
SigningProviders, i.e. ones that can help with Solving.
CWallet::CanGetAddresses() is used to check whether the wallet has available or is able to produce keys for addresses. It uses the ScriptPubKeyMan::CanGetAddresses(), which in turn uses the const KeypoolCountExternalKeys() method, all which do counting and no modifications.
Needed for future ScriptPubKeyMans which may need to create
SigningProviders dynamically and thus a normal pointer is not enough
This commit does not change behavior.

Pull request description:
For wallets with `WALLET_FLAG_DISABLE_PRIVATE_KEYS` this makes the watch-only balance available on the send screen (including coin selection). Instead of sending a transaction it generates a PSBT.
The user can take this PSBT and process it with [HWI](https://github.com/bitcoin-core/HWI) or put it an SD card for hardware wallets that support that.
The PSBT is copied to the clipboard. This was the easiest approach; we can add a dialog later to display it, as well as an option to save to disk.

I might have missed something, but I didn't see a place where multiple batches were used previously and a single batch was used now. So the main benefit of this change appears to be removing a recursive lock? And maybe moving toward a consistent convention for passing batch instances?

Pull request description:
This change is mainly a naming / organization change intended to simplify #10102. It:
- Renames struct InitInterfaces to struct NodeContext and moves it from
src/init.h to src/node/context.h. This is a cosmetic change intended to make
the point of the struct more obvious.
- Gets rid of BanMan and ConnMan globals making them NodeContext members
instead. Getting rid of these globals has been talked about in past as a way
to implement testing and simulations. Making them NodeContext members is a
way of keeping them accessible without the globals.
- Splits g_rpc_interfaces global into g_rpc_node and g_rpc_chain globals. This
better separates node and wallet rpc methods. Node RPC methods should have
access NodeContext, while wallet RPC methods should only have indirect access
to node functionality via interfaces::Chain.
- Adds NodeContext& references to interfaces::Chain class and the
interfaces::MakeChain() function. This is needed to access ConnMan and BanMan
instances without the globals.
- Gets rid of redundant Node and Chain instances in Qt tests. This is
needed due to the previous MakeChain change, and also makes test setup a
little more straightforward. More cleanup could be done in the future, but it
will require deduplication of bitcoind, bitcoin-qt, and TestingSetup init
code.

Wallet code should use interfaces::Chain and not directly access to node state.
Add a g_rpc_chain replacement global for wallet code to use, and move
g_rpc_node definition to a libbitcoin_server source file so there are link
errors if wallet code tries to access it.
This moves CWallet members and methods dealing with keys to a new
LegacyScriptPubKeyMan class, and updates calling code to reference the new
class instead of CWallet.
Most of the changes are simple text replacements and variable substitutions
easily verified with:
git log -p -n1 -U0 --word-diff-regex=.
The only nontrivial chunk of code added is the new LegacyScriptPubKeyMan class
declaration, but this code isn't new and is just selectively copied and moved
from the previous CWallet class declaration. This can be verified with:
git log -p -n1 --color-moved=dimmed_zebra src/wallet/scriptpubkeyman.h src/wallet/wallet.h
or

All dead code in `if (!CommitTransaction())` branches has been removed.
Instead of relying on combination of hashBlock and nIndex
values to manage tx in its lifecycle, we introduce 4
status : CONFIRMED, UNCONFIRMED, CONFLICTED, ABANDONED.
hashBlock and nIndex magic values should only be used at
serialization/deserialization for backward-compatibility.
At block disconnection, we know flag txn as UNCONFIRMED where
previously they kept their states until being override by a
block connection or abandontransaction call. This is a change
in behavior for which user may have to call abandon twice
if transaction is disconnected and not accepted back in the mempool.
We assert status transitioning right in AddToWallet. Doing so
flagged a misbehavior in ComputeTimeSmart unit test where same
tx is confirmed twice in different block. To avoid inconsistencies
we unconfirmed tx before new connection in different block. We
also remove a cs_main lock in test, as AddToWallet and its
callees don't rely on locked chain.

d9ff862f2d24784ee081a8f62a76ffdfe409c10a CreateTransaction calls KeepDestination on ReserveDestination before success (Gregory Sanders)
Pull request description:
The typical usage pattern of `ReserveDestination` is to explicitly `KeepDestination`, or `ReturnDestination` when it's detected it will not be used.
Implementers such as myself may fail to complete this pattern, and could result in key re-use: https://github.com/bitcoin/bitcoin/pull/15557#discussion_r271956393
Since ReserveDestination is currently only used directly in the `CreateTransaction`/`CommitTransaction` flow(or fee bumping where it's just used in `CreateTransaction`), I instead make the assumption that if a transaction is returned by `CreateTransaction` it's highly likely that it will be accepted by the caller, and the `ReserveDestination` kept. This simplifies the API as well. There are very few cases where this would not be the case which may result in keys being burned.
Those failure cases appear to be:
`CommitTransaction` failing to get the transaction into the mempool
Belt and suspenders check in `WalletModel::prepareTransaction`

1b699a5083b435c2b79f3951f94ac9f967d24f6c Add HaveKey and HaveCScript to SigningProvider (Andrew Chow)
Pull request description:
This PR compresses the `CWallet` chain of inheritance from 5 classes to 3 classes. `CBasicKeyStore` is renamed to `FillableSigningProvider` and some parts of it (the watchonly parts) are moved into `CWallet`. `CKeyStore` and `CCrypoKeyStore` are completely removed. `CKeyStore`'s `Have*` functions are moved into `SigningProvider` and the `Add*` moved into `FillableSigningProvider`, thus allowing it to go away entirely. `CCryptoKeyStore`'s functionality is moved into `CWallet`. The new inheritance chain is:
```
SigningProvider -> FillableSigningProvider -> CWallet
```
`SigningProvider` now is the class the provides keys and scripts and indicates whether keys and scripts are present. `FillableSigningProvider` allows keys and scripts to be added to the signing provider via `Add*` functions. `CWallet` handles all of the watchonly stuff (`AddWatchOnly`, `HaveWatchOnly`, `RemoveWatchOnly` which were previously in `CKeyStore`) and key encryption (previously in `CCryptoKeyStore`).
Implements the 2nd [prerequisite](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes#cwallet-subclass-stack) from the wallet restructure.

re-ACK 93ce4a0; it keeps `EncryptSecret`, `DecryptSecret` and `DecryptKey` in `wallet/crypter.cpp`, but makes them not static. It improves alphabetical includes, reorders some function definitions, fixes commit message, brings back lost code comment.

172213be5b174243dc501c1103ad5fe2fee67a16 Add GetNewDestination to CWallet to fetch new destinations (Andrew Chow)
Pull request description:
The wallet should give out destinations instead of keys. It should be the one that handles the conversion from key to destination and the setting of the label, not the caller. In order to do this, two new member functions are introduced `GetNewDestination()` and `GetNewChangeDestination()`. Additionally, `CReserveKey` is changed to be `ReserveDestination` and represents destinations whose keys can be returned to the keypool.
