876eb64680 [wallet] Pass error message back from CWallet::Verify()
Pass an error message back from CWallet::Verify(), and call
InitError/InitWarning from WalletInit::Verify().

This means that we can call CWallet::Verify() independently from
WalletInit and not have InitErrors printed to stdout. It also means that
the error can be reported to the user if dynamic wallet load fails.

e0e90db07b [wallet] Add CWallet::Verify function
This allows a single wallet to be verified. Prior to this commit, all
wallets were verified together by the WalletInit::Verify() function at
start-up.

Individual wallet verification will be done when loading wallets
dynamically at runtime.

470316c3bf [wallet] setup wallet background flushing in WalletInit directly
WalletInit::Start calls postInitProcess() for each wallet. Previously
each call to postInitProcess() would attempt to schedule wallet
background flushing.

Just start wallet background flushing once from WalletInit::Start().

dfcd9f3e6a Use a keypool of presplit keys after upgrading to hd chain split
After upgrading to HD chain split, we want to continue to use keys
from the old keypool. To do this, before we generate any new keys after
upgrading, we mark all of the keypool entries as being pre-chain
split and move them to a separate pre chain split keypool. Keys are
fetched from that keypool until it is emptied. Only then are the new
internal and external keypools used.

5c50e93d52 Allow -upgradewallet to upgradewallets to HD
Changes the maximum upgradewallet version to the latest wallet version
number, 159900. Non-HD wallets will be upgraded to use HD derivation.
Non HD chain split wallets will be upgraded to HD chain split.

If a non-HD wallet is upgraded to HD, the keypool will be entirely
regenerated.

Since upgradewallet is effectively run during a first run, all of the
first run initial setup stuff is combined with the upgrade to HD

Merge #12729: Get rid of ambiguous OutputType::NONE value
1e46d8a Get rid of ambiguous OutputType::NONE value (Russell Yanofsky)

Pull request description:

  Based on suggestion by @sipa https://github.com/bitcoin/bitcoin/pull/12119#issuecomment-357982763

  After #12119, the NONE output type was overloaded to refer to either an output type that couldn't be parsed, or to an automatic change output mode.  This change drops the NONE enum and uses a simple bool to indicate parse failure, and a new CHANGE_AUTO enum to refer the change output type.

  This change is almost a pure refactoring except it makes RPCs reject empty string ("") address types instead of treating them like they were unset. This simplifies the parsing code a little bit and could prevent RPC usage mistakes. It's noted in the release notes.

  Follows up #12408 by @MarcoFalke

Merge #12892: [wallet] [rpc] introduce 'label' API for wallet
41ba061 [docs] Add release notes for wallet 'label' API. (John Newbery)
189e0ef [wallet] [rpc] introduce 'label' API for wallet (Wladimir J. van der Laan)

Pull request description:

  Add label API to wallet RPC.

  This is one step towards #3816 ("Remove bolt-on account system") although it doesn't
  actually remove anything yet.

  These initially mirror the account functions, with the following differences:

  - These functions aren't DEPRECATED in the help
  - Help mentions 'label' instead of accounts. In the language used, labels are
    associated with addresses, instead of addresses associated with labels. (unlike
    with accounts.)
  - Labels have no balance
    - No balances in `listlabels`
    - `listlabels` has no minconf or watchonly argument
  - Like in the GUI, labels can be set on any address, not just receiving addreses
  - Unlike accounts, labels can be deleted.
    Being unable to delete them is a common annoyance (see #1231).
    Currently only by reassigning all addresses using `setlabel`, but an explicit
    call `deletelabel` which assigns all address to the default label may make
    sense.

Merge #12731: Support serialization as another type without casting
818dc74 Support serialization as another type without casting (Pieter Wuille)

Pull request description:

  This adds a `READWRITEAS(type, obj)` macro which serializes `obj` as if it were converted to `const type&` when `const`, and to `type&` when non-`const`. No actual cast is involved, so this only works when this conversion can be done automatically.

  This makes it usable in serialization code that uses a single implementation for both serialization and deserializing, which doesn't know the constness of the object involved.

  This is a redo of #12712, using a slightly different interface.

045eeb8 Rename account to label where appropriate (Russell Yanofsky)

Pull request description:

  Rename account to label where appropriate

  This change only updates strings and adds RPC aliases, but should simplify the implementation of address labels in https://github.com/bitcoin/bitcoin/pull/7729, by getting renaming out of the way and letting that change focus on semantics.

  The difference between accounts and labels is that labels apply only to addresses, while accounts apply to both addresses and transactions (transactions have "from" and "to" accounts). The code associating accounts with transactions is clumsy and unreliable so we would like get rid of it.

Pull request description:

  This is an implementation of the [Branch and Bound coin selection algorithm written by Murch](http://murch.one/wp-content/uploads/2016/11/erhardt2016coinselection.pdf) (@xekyo). I have it set so this algorithm will run first and if it fails, it will fall back to the current coin selection algorithm. The coin selection algorithms and tests have been refactored to separate files instead of having them all in wallet.cpp.

  I have added some tests for the new algorithm and a test for all of coin selection in general. However, more tests may be needed, but I will need help with coming up with more test cases.

  This PR uses some code borrowed from #10360 to use effective values when selecting coins.

Pull request description:

  Two commits:

  - `Construct CWalletTx objects in CommitTransaction` moves a bunch of CWalletTx initialization into CWallet::CommitTransaction to dedup some code and avoid future inconsistencies in how wallet transactions are created.
  - `Get rid of CWalletTx default constructor` does what is described and eliminates the possibility of empty transaction entries being inadvertently created by mapWallet[hash] accesses.

  Both of these changes were originally part of #9381

No change in behavior in the normal case. But buggy mapWallet lookups with

be8ab7d082 Create new wallet databases as directories rather than files
This change should make it easier for users to make complete backups of wallets
because they can now just back up the specified `-wallet=<path>` path directly,
instead of having to back up the specified path as well as the transaction log
directory (for incompletely flushed wallets).

Another advantage of this change is that if two wallets are located in the same
directory, they will now use their own BerkeleyDB environments instead using a
shared environment. Using a shared environment makes it difficult to manage and
back up wallets separately because transaction log files will contain a mix of
data from all wallets in the environment.

    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.

Merge #10498: Use static_cast instead of C-style casts for non-fundamental types
9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift)

Pull request description:

  A C-style cast is equivalent to try casting in the following order:

  1. `const_cast(...)`
  2. `static_cast(...)`
  3. `const_cast(static_cast(...))`
  4. `reinterpret_cast(...)`
  5. `const_cast(reinterpret_cast(...))`

  By using `static_cast<T>(...)` explicitly we avoid the possibility of an unintentional and dangerous `reinterpret_cast`. Furthermore `static_cast<T>(...)` allows for easier grepping of casts.

  For a more thorough discussion, see ["ES.49: If you must use a cast, use a named cast"](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#es49-if-you-must-use-a-cast-use-a-named-cast) in the C++ Core Guidelines (Stroustrup & Sutter).
