Pull request description:
This refactors most of the logic in TxIndex into a reusable base class for other indices. There are two commits moving code between files, which may be be more easily reviewed using `git diff --color-moved` (https://blog.github.com/2018-04-05-git-217-released/).
The motivation for this is to support BIP 157 by indexing block filters.

Pull request description:
This PR adds an optional (off by default) `-avoidpartialspends` flag, which changes coin select to use output groups rather than outputs, where each output group corresponds to all outputs with the same destination.
It is a privacy improvement, as each time you spend some output, any other output that is publicly associated with the destination (address) will also be spent at the same time, at the cost of fee increase for cases where coin select without group restriction would find a more optimal set of coins (see example below).
For regular use without address reuse, this PR should have no effect on the user experience whatsoever; it only affects users who, for some reason, have multiple outputs with the same destination (i.e. address reuse).
Nodes with this turned off will still try to avoid partial spending, if the fee of the resulting transaction is not greater than the fee of the original transaction.
Example: a node has four outputs linked to two addresses `A` and `B`:
* 1.0 btc to `A`
* 0.5 btc to `A`
* 1.0 btc to `B`
* 0.5 btc to `B`
The node sends 0.2 btc to `C`. Without `-avoidpartialspends`, the following coin selection will occur:
* 0.5 btc to `A` or `B` is picked
* 0.2 btc is output to `C`
* 0.3 - fee is output to (unique change address)
With `-avoidpartialspends`, the following will instead happen:
* Both of (0.5, 1.0) btc to `A` or `B` is picked (one or the other pair)
* 0.2 btc is output to `C`
* 1.3 - fee is output to (unique change address)
As noted, the pro here is that, assuming nobody sends to the address after you spend from it, you will only ever use one address once. The con is that the transaction becomes slightly larger in this case, because it is overpicking outputs to adhere to the no partial spending rule.
This complements #10386, in particular it addresses @luke-jr and @gmaxwell's concerns in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-300667926 and https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381.
Together with `-avoidreuse`, this fully addresses the concerns in #10065 I believe.

Pull request description:
I'm re-opening #11857 as a new pull request because the last one stopped loading for people
-------------------------------
This refactors the tx index code to be in it's own class and get built concurrently with validation code. The main benefit is decoupling and moving the txindex into a separate DB. The primary motivation is to lay the groundwork for other indexers that might be desired (such as the [compact filters](https://github.com/bitcoin/bips/pull/636)). The basic idea is that the TxIndex spins up its own thread, which first syncs the txindex to the current block index, then once in sync the BlockConnected ValidationInterface hook writes new blocks.
### DB changes
At the suggestion of some other developers, the txindex has been split out into a separate database. A data migration runs at startup on any nodes with a legacy txindex. Currently the migration blocks node initialization until complete.
### Open questions
- Should the migration of txindex data from the old DB to the new DB block in init or should it happen in a background thread? The downside to backgrounding it is that `getrawtransaction` would return an error message saying the txindex is syncing while the migration is running.
### Impact
In a sample size n=1 test where I synced nodes from scratch, the average time [Index writing](https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp#L1903) was 3.36ms in master and 1.72ms in this branch. The average time between `UpdateTip` log lines for sequential blocks between 400,000 and IBD end on mainnet was 0.297204s in master and 0.286134s in this branch. Most likely this is just variance in IBD times, but I can try with some more trials if people want.

Seems like older versions of macOS pretend to support c++17 std libs but do not have/have issues with uncaught_exceptions. "Catch", the testing framework used in the bls lib wants those by default but setting `DCATCH_CONFIG_NO_CPP17_UNCAUGHT_EXCEPTIONS` disables them which should be just fine to do in all cases here.

Pull request description:
This PR contains some of the changes left as TODO in #11167 (and built on top of that PR). They are not intended for backporting.
This removes the `CBase58`, `CBitcoinSecret`, `CBitcoinExtKey`, and `CBitcoinExtPubKey` classes, in favor of simple `Encode`/`Decode` functions. Furthermore, all Bitcoin-specific logic (addresses, WIF, BIP32) is moved to `key_io.{h,cpp}`, leaving `base58.{h,cpp}` as a pure utility that implements the base58 encoding/decoding logic.

9272d70 Support serializing Span<unsigned char> and use that instead of FLATDATA (Pieter Wuille)
833bc08 Add Slice: a (pointer, size) array view that acts like a container (Pieter Wuille)
Pull request description:
Introduce a new data type `Span`, which is an encapsulated pointer + size (like C++20's `std::span` or LevelDB's `Slice`), and represents a view to a sequence of objects laid out continuously in memory.
The immediate use case is replacing the remaining `FLATDATA` invocations. Instead of those, we support serializing/deserializing unsigned char `Span`s (treating them as arrays).
A longer term goal for `Span`s is making the script execution operate on them rather than on `CScript` itself. This will allow separate storage mechanisms for scripts.

1e79c055cd Split signrawtransaction into wallet and non-wallet (Andrew Chow)
Pull request description:
This PR is part of #10570. It also builds on top of #10571.
This PR splits `signrawtransaction` into two commands, `signrawtransactionwithkey` and `signrawtransactionwithwallet`. `signrawtransactionwithkey` requires private keys to be passed in and does not use the wallet for any signing. `signrawtransactionwithwallet` uses the wallet to sign a raw transaction and does not have any parameters to take private keys.
The `signrawtransaction` RPC has been marked as deprecated and will call the appropriate RPC command based upon the parameters given. A test was added to check this behavior is still consistent with the original behavior.
All tests that used `signrawtransaction` have been updated to use one of the two new RPCs. Most uses were changed to `signrawtransactionwithwallet`. These were changed via a scripted diff.

Pull request description:
This adds configure options for `-fsanitize=address`, `-fsanitize=thread`, and `-fsanitize=undefined` which are all disabled by default. These flags are useful for developers who wish to do additional safety checking. Note that some of these are mutually incompatible, and these may have a large performance overhead.
There's some kind of strange logic required to properly check for the availability of these flags in a way that works on both GCC and Clang, hopefully the comments make it clear what's going on.

98b181323 [build] Tune wildcards for LIBSECP256K1 target (Karl-Johan Alm)
Pull request description:
Automake would think the target was out of date every time because e.g. '.deps' was updated.
Note: I am assuming that secp256k1 depends on `*.h`, `*.c`, ~~and `libsecp256k1-config.h`~~ (it's `.h` so already included), aside from pre-existing `include/*`. If there are other files that would require a rebuild of the `LIBSECP256K1` target, they should probably be added.
It would be neat if you could exclude specific files, rather than split it up like this, but it doesn't seem possible (https://www.gnu.org/software/make/manual/html_node/Wildcard-Function.html#Wildcard-Function)
Should probably note this:

471a4992d4a4477d7e234a82d3639d06f4572e9a Move rpc/util.cpp from libbitcoin-util to libbitcoin-server (Chun Kuan Lee)
Pull request description:
The functions in `rpc/util.cpp` would call functions in `script/standard.cpp` which in libbitcoin-common. This could cause problem if the linker does not strip out unused function while linking `bitcoin-cli`.

7da3b0a rpc: Move RPC_FORBIDDEN_BY_SAFE_MODE code to reserved section (Wladimir J. van der Laan)
2ae705d Remove Safe mode (Andrew Chow)
Pull request description:
Rebase of #10563. Safe mode was [disabled by default and deprecated in 0.16](https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.16.0.md#safe-mode-disabled-by-default), so probably should be removed for 0.17.
> Rationale:
>
> Safe mode is useless. It only disables some RPC commands when large work forks are detected. Nothing else is affected by safe mode. It seems that very few people would be affected by safe mode. The people who use Core as a wallet are primarily using it through the GUI, which safe mode does not effect. In the GUI, transactions will still be made as normal; only a warning is displayed.
>
> I also don't think that we should be disabling RPC commands or any functionality in general. If we do, it should be done consistently, which safe mode is not. If we want to keep the idea of a safe mode around, I think that the current system needs to go first before a new system can be implemented.

Pull request description:
This implements the compact block filter construction in [BIP 158](https://github.com/bitcoin/bips/blob/master/bip-0158.mediawiki). The code is not used anywhere in the Bitcoin Core code base yet. The next step towards [BIP 157](https://github.com/bitcoin/bips/blob/master/bip-0157.mediawiki) support would be to create an indexing module similar to `TxIndex` that constructs the basic and extended filters for each validated block.
### Filter Sizes
[Here](https://gateway.ipfs.io/ipfs/QmRqaAAQZ5ZX5eqxP7J2R1MzFrc2WDdKSWJEKtQzyawqog) is a CSV of filter sizes for blocks in the main chain.
As you can see below, the ratio of filter size to block size drops after the first ~150,000 blocks:
The reason for the relatively large filter sizes is that Golomb-coded sets only achieve good compression with a sufficient number of elements. Empirically, the average element size with 100 elements is 14% larger than with 10,000 elements.
The ratio of filter size to block size is computed without witness data for basic filters. Here is a summary table of filter size ratios *for blocks after height 150,000*:
| Stat | Filter Type |
|-------|--------------|
| Weighted Size Ratio Mean | 0.0198 |
| Size Ratio Mean | 0.0224 |
| Size Ratio Std Deviation | 0.0202 |
| Mean Element Size (bits) | 21.145 |
| Approx Theoretical Min Element Size (bits) | 21.025 |
