172f5fa738 Support deserializing into temporaries (Pieter Wuille)
2761bca997 Merge READWRITEMANY into READWRITE (Pieter Wuille)
Pull request description:
This is another fragment of improvements from #10785.
The current serialization code does not support serializing/deserializing from/to temporaries (like `s >> CFlatData(script)`). As a result, there are many invocations of the `REF` macro which in addition to changing the reference type also changes the constness. This is unnecessary in C++11 as we can use rvalue references now instead.
The first commit is an extra simplification we can make that removes the duplication of code between `READWRITE` and `READWRITEMANY` (and related functions).

Pull request description:
This change moves down model data querying to where it's needed. The worst case remains the same (all data is queried and the row passes) but for the average case it improves the filter performance.

f98b54352 Only call NotifyBlockTip when the active chain changes (James O'Beirne)
152b7fb25 [tests] Add a (failing) test for waitforblockheight (James O'Beirne)
Pull request description:
This is a subset of the more controversial https://github.com/bitcoin/bitcoin/pull/12407, but this also adds a test demonstrating the bug.
In InvalidateBlock, we're calling NotifyBlockTip with the now-invalid block's prev regardless of what chain the ancestor block is on. This could create numerous issues, but it at least screws up `waitforblockheight` (or anything else relying on `rpc/blockchain.cpp:latestblock`) when InvalidateBlock is called on a block not in chainActive, which can happen via RPC.
Only call NotifyBlockTip when the block being marked invalid is on the active chain.

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.

b4bc32a451 [wallet] Get rid of CWalletTx default constructor (Russell Yanofsky)
a128bdc9e1 [wallet] Construct CWalletTx objects in CommitTransaction (Russell Yanofsky)
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

Currently, the READWRITE macro cannot be passed any non-const temporaries, as
the SerReadWrite function only accepts lvalue references.
Deserializing into a temporary is very common, however. See for example
things like 's >> VARINT(n)'. The VARINT macro produces a temporary wrapper
that holds a reference to n.
Fix this by accepting non-const rvalue references instead of lvalue references.
We don't propagate the rvalue-ness down, as there are no useful optimizations
that only apply to temporaries.
Then use this new functionality to get rid of many (but not all) uses of the
'REF' macro (which casts away constness).

42343c748 Split up and sanitize CAccountingEntry serialization (Pieter Wuille)
029ecac1b Split up and sanitize CWalletTx serialization (Pieter Wuille)
Pull request description:
This is a small subset of changes taken from #10785, fixing a few of the craziest constness violations in the serialization code.
`CWalletTx` currently serializes some of its fields by embedding them in a key-value `mapValue`, which is modified (and then fixed up) even from the `Serialize` method (for which `mapValue` is const). `CAccountingEntry` goes even further in that it stores such a map by appending it into `strComment` after a null char, which is again later fixed up again.
Fix this by splitting the serialization and deserialization code, and making the serialization act on a copy of `mapValue` / `strComment`.

8acd25d85 rpc: Allow typeAny in RPCTypeCheck (MarcoFalke)
Pull request description:
The second parameter of the `createrawtransaction` is a dictionary of the outputs. This comes with at least two drawbacks:
* In case of duplicate keys, either of them might silently disappear, with no user feedback at all. A user needs to make other mistakes, but this could eventually lead to abnormal tx fees.
* A dictionary does not guarantee that keys are sorted. Again, a user needs to keep this in mind, as it could eventually lead to excessive tx fees.
Even though my scenario of loss-of-funds is unlikely to happen, I see it as a inconvenience that should be fixed.

Allows SelectCoinsMinConf and SelectCoins be able to switch between
using BnB or Knapsack for choosing coins.
Has SelectCoinsMinConf do the preprocessing necessary to support either
BnB or Knapsack. This includes calculating the filtering the effective
values for each input.
Uses BnB in CreateTransaction to find an exact match for the output.
If BnB fails, it will fallback to the Knapsack solver.
Moves the current coin selection algorithm out of SelectCoinsMinConf
and puts it in coinselection.{cpp,h}. The new function, KnapsackSolver,
instead of taking a vector of COutputs, will take a vector of CInputCoins
that is prepared by SelectCoinsMinConf.
Changes CInputCoin to coinselection and to use CTransactionRef in
order to avoid a circular dependency. Also moves other coin selection
specific variables out of wallet.h to coinselectoin.h
f4b68b3f8f Log fatal LevelDB errors more verbosely (Evan Klitzke)
Pull request description:
The `leveldb::Status` class logs the filename of corrupted files, which might be useful when looking at error reports from usres. In theory this is already logged via the `LogPrintf()` statement in `HandleError()`, but that may not always be close to where the final error message is logged, e.g. see https://github.com/bitcoin/bitcoin/issues/11355#issuecomment-340340542 where the log trace provided by the user does not contain that information (and other user comments in the same issue).
This also adds a log message instructing the user to run the process with `-debug=leveldb`, which provides much more verbose error messages about LevelDB internals. This may not really help much, but improving the error messages here can't hurt.

* Z is the zone designator for the zero UTC offset.
* T is the delimiter used to separate date and time.
This makes it clear for the end-user that the date/time logged is
specified in UTC and not in the local time zone.
No change in behavior in the normal case. But buggy mapWallet lookups with
invalid txids will now throw exceptions instead of inserting dummy entries into
the map, and potentially causing segfaults and other failures.
This also makes it a compiler error to use the mapWallet[hash] syntax which
could create dummy entries.
Construct CWalletTx objects in CWallet::CommitTransaction, instead of having
callers do it. This ensures CWalletTx objects are constructed in a uniform way
and all fields are set.
This also makes it possible to avoid confusing and wasteful CWalletTx copies in
https://github.com/bitcoin/bitcoin/pull/9381
There is no change in behavior.

be8ab7d08 Create new wallet databases as directories rather than files (Russell Yanofsky)
26c06f24e Allow wallet files not in -walletdir directory (Russell Yanofsky)
d8a99f65e Allow wallet files in multiple directories (Russell Yanofsky)
Pull request description:
This change consists of three commits:
* The first commit is a pure refactoring that removes the restriction that two wallets can only be opened at the same time if they are contained in the same directory.
* The second commit removes the restriction that `-wallet` filenames can only refer to files in the `-walletdir` directory.
* The third commit makes second commit a little safer by changing bitcoin to create wallet databases as directories rather than files, so they can be safely backed up.
All three commits should be straightforward:
* The first commit adds around 20 lines of new code and then updates a bunch of function signatures (generally updating them to take plain fs::path parameters, instead of combinations of strings, fs::paths, and objects like CDBEnv and CWalletDBWrapper).
* The second commit removes two `-wallet` filename checks and adds some test cases to the multiwallet unit test.
* The third commit just changes the mapping from specified wallet paths to bdb environment & data paths.
