ef2d515af3 [wallet] move-only: move CReserveKey to be next to CKeyPool (John Newbery)
Pull request description:
Docs/move-only
Adds doxygen comments for the CKeyPool and CReserveKey objects. The way these work is pretty confusing and it's easy to overlook details (eg https://github.com/bitcoin/bitcoin/pull/15557#discussion_r271956393).
These are on the verbose side, but I think too much commenting is better than not enough. Happy to take feedback on what's an appropriate level.

Trying to use them results in "Error parsing command line arguments: Invalid parameter" error. Should either add them to hidden_args or drop them. The latter seems like a better option since no one should be using them by now anyway.

Pull request description:
Instead of removing the database transaction logs and retrying the
wallet loading, just return an error message to the user. Additionally,
speciically for DB_RUNRECOVERY, notify the user that this could be due
to different BDB versions.

This PR:
- makes GUI error messages bilingual: user's native language + untranslated (i.e. English)
- insures that only untranslated messages are written to the debug log file and to `stderr` (that is not the case on master).
If a translated string is unavailable only an English string appears to a user.
Here are some **examples** (updated):

bd9c6ade46c8c29bea3fd5df62a35efadb77ac89 wallet: Fixed Grammatical error in bdb.h (zealsham)
Pull request description:
A comment in bdb.h file in the wallet directory contains a grammatical error that makes the underlying code harder to reason about .
The comment which says `/** Indicate the a new database user has began using the database. */` should actually be
`/** indicate that a new database user has began using the database. */`. The former is quite confusing , and leaves you wondering what "the a new database user " is refering to . This pull request thus provides value to the bitcoin codebase by improving readability .

2dbfb37b407ed23b517f507d78fb77334142dce5 Fix Char as Bool in interfaces (Jeremy Rubin)
Pull request description:
In a few places in src/wallet/wallet.h, we use a char when semantically we want a bool.
This is kind of an issue because it means we can unserialize the same transaction with different fFromMe flags (as differing chars) and evaluate the following section in wallet/wallet.cpp
```c++
if (wtxIn.fFromMe && wtxIn.fFromMe != wtx.fFromMe)
{
wtx.fFromMe = wtxIn.fFromMe;
fUpdated = true;
}
```
incorrectly (triggering an fUpdated where both fFromMe values represent true, via different chars).
I don't think this is a vulnerability, but it's just a little messy and unsemantic, and could lead to issues with stored wtxIns not being findable in a map by their hash.
The serialize/unserialize code for bool internally uses a char, so it should be safe to make this substitution.
NOTE: Technically, this is a behavior change -- I haven't checked too closely that nowhere is depending on storing information in this char. Theoretically, this could break something because after this change a tx unserialized with such a char would preserve it's value, but now it is converted to a ~true~ canonical bool.

2) The rpc call had two separate `replaceable` arguments, each of which being used in mutually exclusive places. I preserved the `options` version to retain compatability with `fundtransaction`.

99cccb900 Add a method to add a pubkey to the keypool (Andrew Chow)
Pull request description:
If the wallet has private keys disabled, allow importing public keys into the keypool. A `keypool` option has been added to `importmulti` in order to signal that the keys should be added to the keypool.

Using wallet flags should be enough here, no need for any additional conditions.
NOTE: Wallets created prior to 4627 have wallet version set to FEATURE_HD even when no HD chain was initialized, that's why they have issues without this fix.

0bedcbafd Use a single wallet batch for UpgradeKeyMetadata (Jonas Schnelli)
Pull request description:
Opening wallets (the first time) after #14021 took on my end around 30 seconds due to the keymetadata migration (tested on regtest).
Using a single wallet batch reduces the required time for the migration down to <1s on my system for a default 2k keypool wallet.

c45415f73 Refactor keymetadata writing to a separate method (Andrew Chow)
Pull request description:
This PR allows for key origin data as defined by the descriptors document to be imported to the wallet when importing a descriptor using `importmulti`. This allows the `walletprocesspsbt` to include the BIP 32 derivation paths for keys that it is watching that are from a different HD wallet.
In order to make this easier to use, a new field `hdmasterkeyfingerprint` has been added to `getaddressinfo`. Additionally I have removed `hdmasterkeyid` as was planned. I think that this API change is fine since it was going to be removed in 0.18 anyways. `CKeyMetadata` has also been extended to store key origin info to facilitate this.

* style: use clang-tidy style named parameters
* refactor: make IsTimeOutOfBounds testable by having current time be a parameter
* style: use x-> not (*x).
* refactor: make SelectCoinsGroupedByAddresses return a vector, remove out param
previous semantics was return false if the vecTally vector was empty. Now we just let the caller check if it is empty or not
* refactor: fix some sign-compare warnings
* refactor: consistently pre-declare stuff as struct / class inline with underlying type
* refactor: don't return const bool
* refactor: use ref to string
* refactor: use = default for CompactTallyItem
* refactor: adjust "initialization" ordering
* refactor: adjust how we handle negatives in GetProjectedMNPayees, use std::min
* refactor: don't bind a reference to a temporary value
* refactor: use a ref
* refactor: ensure attempt in SelectMemberForRecovery is non-negative.
* refactor: remove unused this capture
* refactor: fix numerous sign-compare warnings
* refactor: more consistently use size_t, use empty()

5c1b9714cb0a13be28324f91f4ec9ca66a1de8c7 wallet: Fix -maxtxfee check by moving it to CWallet::CreateTransaction (João Barbosa)
Pull request description:
Follow up to #16257, this PR makes `bumpfee` aware of `-maxtxfee`.
It also prevents dangling locked unspents when calling `fundrawtransaction` - because the previous check was after `LockCoin`.

re-ACK 0d101a340c44841cbbc5982d55354b1787bc39e2, only change is small test fixup

7ba2d57852 Fix ListCoins test failure due to unset g_wallet_allow_fallback_fee (Russell Yanofsky)
Pull request description:
New global variable was introduced in #11882 and not setting it causes:
```
wallet/test/wallet_tests.cpp(638): error in "ListCoins": check wallet->CreateTransaction({recipient}, wtx, reservekey, fee, changePos, error, dummy) failed
wallet/test/wallet_tests.cpp(679): error in "ListCoins": check list.begin()->second.size() == 2 failed [1 != 2]
wallet/test/wallet_tests.cpp(686): error in "ListCoins": check available.size() == 2 failed [1 != 2]
wallet/test/wallet_tests.cpp(705): error in "ListCoins": check list.begin()->second.size() == 2 failed [1 != 2]
```
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.
This is similar to bugs #12150 and #12424. Example travis failures are:
