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.

Merge #11742: rpc: Add testmempoolaccept
b55555d rpc: Add testmempoolaccept (MarcoFalke)

Pull request description:

  To check if a single raw transaction makes it into the current transaction pool, one had to call `sendrawtransaction`. However, on success, this adds the transaction to the mempool with no easy way to undo.

  The call `testmempoolaccept` is introduced to provide a way to solely check the result without changing the mempool state.

Pull request description:

  The tests are a little bit slow, mempool_persist.py goes from about 20 s to about 120 s in my hardware.
  Perhaps there's a better way to test this.

Merge #12653: Allow to optional specify the directory for the blocks storage
a192636 -blocksdir: keep blockindex leveldb database in datadir (Jonas Schnelli)
f38e4fd QA: Add -blocksdir test (Jonas Schnelli)
386a6b6 Allow to optional specify the directory for the blocks storage (Jonas Schnelli)

Pull request description:

  Since the actual block files taking up more and more space, it may be desirable to have them stored in a different location then the data directory (use case: SSD for chainstate, etc., HD for blocks).

  This PR adds a `-blocksdir` option that allows one to keep the blockfiles and the blockindex external from the data directory (instead of creating symlinks).

  I fist had an option to keep the blockindex within the datadir, but seems to make no sense since accessing the index will (always) lead to access (r/w) the block files.

Pull request description:

  From the branches-I've-had-lying-around-and-forgot-to-PR department...

  This is a comment-only PR, but the comments point out an API quirk that isn't exactly trivial. None of our use-cases right now hit this, but if we were to call SyncWithValidationInterfaceQueue (eg to limit queue depth) in ATMP, I'm pretty sure we'd hit a deadlock there.

d45b344ffd Bucket for inbound when scheduling invs to hide tx time (Gleb)

Pull request description:

  It has been brought up to my attention that current random delays mechanism (originally intended to obfuscate transaction metadata) allows to easily estimate the time a transaction was received by a node.

  It may be done by connecting multiple observer nodes to the same node. Each of those nodes will generate its own schedule of delays. Combined metadata regarding those events from different sources allows an observer to estimate transaction time.

  After this patch a spy won't gain additional information by just creating multiple connections to a target.

Backport 10279 (#3394)
* Merge #10279: Add a CChainState class to validation.cpp to take another step towards clarifying internal interfaces

22fddde Avoid calling GetSerializeSize on each tx in a block if !fTxIndex (Matt Corallo)
2862aca Move some additional variables into CChainState private (Matt Corallo)
fd4d80a Create initial CChainState to hold chain state information (Matt Corallo)

50701ba Move txindex/undo data disk location stuff out of ConnectBlock (Matt Corallo)
93a34cf Make DisconnectBlock unaware of where undo data resides on disk (Matt Corallo)

Pull request description:

  CChainState should eventually, essentially, be our exposed "libconsensus", but we're probably a few releases away, so the real goal is to clarify our internal interfaces. The main split was a big step, but validation.cpp is still a somewhat ranomly-mixed bag of functions that are pure functions which validate inputs (which should probably either merge with their callers or move into another file in consensus/), read/write data from disk, manipulate our current chain state (which moves into CChainState), and do mempool transaction validation.

  Obviously this is only a small step, but some effort is made to clean up what functions the functions in CChainState call, and obviously as things are added its easy to keep clear "CChainState::* cannot call anything except via callbacks through CValidationInterface, pure functions, or disk read/write things". Right now there are some glaring violations in mempool callbacks, and general flushing logic needs cleaning up (FlushStateToDisk maybe shouldnt be called, and there should be an API towards setDirtyBlockIndex, but I'll leave that for after @sipa's current changesets land).

  First commit just removes default arguments from `AcceptToMemoryPool` and consolidates two arguments, it does not change behavior.

  Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)

  Use `std::unique_ptr` (C++11) where possible.

  Rationale:
  1. Avoid resource leaks (specifically: forgetting to `delete` an object created using `new`)
  2. Avoid undefined behaviour (specifically: double `delete`:s)

  **Note to reviewers:** Please let me know if I've missed any obvious `std::unique_ptr` candidates. Hopefully this PR should cover all the trivial cases.

  Does implement BIP159, but only the signalling part. No connections are made to NODE_NETWORK_LIMITED in this PR.

  The address relay and connection work (the more complicated part) can then be separated (probably in #10387).

Pull request description:

  [Reviewer hint: use [?w=1](https://github.com/bitcoin/bitcoin/pull/10275/files?w=1) to avoid seeing a bunch of indentation changes.]

  Presuming a user knows the block hash of the block containing a given transaction, this PR allows them to fetch the raw transaction, even without `-txindex`. It also enables support for getting transactions that are in orphaned blocks.

  Note that supplying a block hash will override mempool and txindex support in `GetTransaction`. The rationale behind this is that a transaction may be in multiple places (orphaned blocks) and if the user supplies an explicit block hash it should be adhered to.

  ```Bash
  $ # a41.. is a tx inside an orphan block ..3c6f.. -- first try getting it normally
  $ ./bitcoin-cli getrawtransaction a41e66ee1341aa9fb9475b98cfdc1fe1261faa56c0a49254f33065ec90f7cd79 1
  error code: -5
  error message:
  No such mempool transaction. Use -txindex to enable blockchain transaction queries. Use gettransaction for wallet transactions.

36d326e8b Use nullptr instead of zero (0) as the null pointer constant (practicalswift)

Pull request description:

  Use `nullptr` instead of zero (0) as the null pointer constant.

  The road towards `nullptr` (C++11) is split into two PRs:
  * `NULL` → `nullptr` is handled in PR #10483 (scripted)
  * `0` → `nullptr` is handled in PR #10645 (manual, this PR)

  By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.

  For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
  Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf

Pull request description:

  Adds a simple parameterless rpc command to dump the mempool.

  Rationale:

  Sometimes there can be a crash for whatever reason (bug, power loss, etc) causing the mempool.dat file to not be saved.

  This change allows to script/cron the rpc call to have more regular saves to the file as well as cli/ad-hoc.

37886d5e2 Disconnect outbound peers relaying invalid headers (Suhas Daftuar)
4637f1852 moveonly: factor out headers processing into separate function (Suhas Daftuar)

Pull request description:

  Alternate to #11446.

  Disconnect outbound (non-manual) peers that serve us block headers that are already known to be invalid, but exempt compact block announcements from such disconnects.

  We restrict disconnection to outbound peers that are using up an outbound connection slot, because we rely on those peers to give us connectivity to the honest network (our inbound peers are not chosen by us and hence could all be from an attacker/sybil).  Maintaining connectivity to peers that serve us invalid headers is sometimes desirable, eg after a soft-fork, to protect unupgraded software from being partitioned off the honest network, so we prefer to only disconnect when necessary.

  Compact block announcements are exempted from this logic to comply with BIP 152, which explicitly permits nodes to relay compact blocks before fully validating them.

Pull request description:

  As discussed briefly here: https://botbot.me/freenode/bitcoin-core-dev/2017-02-28/?msg=81712308&page=4

  This adds a hidden command line option for setting `nMinimumChainWork`, which allows us to test this parameter in our functional tests, as well as allowing for niche use cases like syncing nodes that are otherwise disconnected from the network.

  See also #10345, which proposes a new use of `nMinimumChainWork`.

eda888e Fix some LoadChainTip-related init-order bugs. (Matt Corallo)

Pull request description:

  This does a number of things to clean up chainstate init order,
  fixing some issues as it goes:

  * Order chainstate init more logically - first all of the
    blocktree-related loading, then coinsdb, then
    pcoinsTip/chainActive. Only create objects as needed.

  * More clearly document exactly what is and isn't called in
    -reindex and -reindex-chainstate both with comments noting
    calls as no-ops and by adding if guards.

  * Move the writing of fTxIndex to LoadBlockIndex - this fixes a
    bug introduced in d6af06d68a where
    InitBlockIndex was writing to fTxIndex which had not yet been
    checked (because LoadChainTip hadn't yet initialized the
    chainActive, which would otherwise have resulted in
    InitBlockIndex being a NOP), allowing you to modify -txindex
    without reindex, potentially corrupting your chainstate!

  * Rename InitBlockIndex to LoadGenesisBlock, which is now a more
    natural name for it. Also check mapBlockIndex instead of
    chainActive, fixing a bug where we'd write the genesis block out
    on every start.

  * Move LoadGenesisBlock further down in init. This is a more logical
    location for it, as it is after all of the blockindex-related
    loading and checking, but before any of the UTXO-related loading
    and checking.

  * Give LoadChainTip a return value - allowing it to indicate that
    the UTXO DB ran ahead of the block DB. This just provides a nicer
    error message instead of the previous mysterious
    assert(!setBlockIndexCandidates.empty()) error.

  * Calls ActivateBestChain in case we just loaded the genesis
    block in LoadChainTip, avoiding relying on the ActivateBestChain
    in ThreadImport before continuing init process.

  * Move all of the VerifyDB()-related stuff into a -reindex +
    -reindex-chainstate if guard. It couldn't do anything useful
    as chainActive.Tip() would be null at this point anyway.
