9048575511 Add FindScriptPubKey() to search the UTXO set (Jonas Schnelli)

Pull request description:

  Alternative to #9152.

  This takes `<n>` pubkeys and optionally  `<n>` xpubs (together with a definable lookup windows where the default is 0-1000) and looks up common scripts in the UTXO set of all given or derived keys.

  The output will be an array similar to `listunspent`. That array is compatible with `createrawtransaction` as well as with `signrawtransaction`.

  This makes it possible to prepare sweeps and have them signed in a secure (cold) space.

Merge #13298: Net: Bucketing INV delays (1 bucket) for incoming connections to hide tx time
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.

d58055d25f Move AddAndGetDestinationForScript from wallet to outputype module (Anthony Towns)
9a44db2e46 Add outputtype module (Anthony Towns)

Pull request description:

  Adds an "address_type" parameter that accepts "legacy", "p2sh-segwit", and "bech32" to choose the type of address created. Defaults to "legacy" rather than the value of the `-address-type` option for backwards compatibility.

  As part of implementing this, OutputType is moved from wallet into its own module, and `AddAndGetDestinationForScript` is changed to apply to a `CKeyStore` rather than a wallet, and to invoke `keystore.AddCScript(script)` itself rather than expecting the caller to have done that.

  Fixes #12502

02bbc05310 Rescope g_enable_bip61 to net_processing (Jesse Cohen)

Pull request description:

  As part of a larger effort to decouple net_processing and validation a bit, these are a bunch of simple scope cleanups. I've moved things out of the header file that are only referenced in net_processing and added static (or anonymous namespace) modifiers to everything possible in net_processing.

  There are a handful of functions which could be static except that they are exposed for the sake of unit testing - these are explicitly commented. There has been some discussion of a compile time annotation, but no conclusion has been reached on that yet.

  This is somewhat related to other prs #12934 #13413 #13407 and will be followed by prs that reduce reliance on cs_main to synchronize data structures which are translation unit local to net_processing

  This restores that functionality (when `-deprecatedrpc=accounts`), and also makes it possible to call ``getbalance minconf=<int> include_watchonly=<bool>` when accounts are not being used.

Merge #12944: [wallet] ScanforWalletTransactions should mark input txns as dirty
3c292cc19 ScanforWalletTransactions should mark input txns as dirty (Gregory Sanders)

Pull request description:

  I'm hitting a corner case in my mainnet wallet where I load a restore a wallet, call `rescanblockchain` from RPC, and it's "double counting" an output I've sent to myself since currently it never marks input transactions as dirty. This is fixed by a restart of the wallet.

  Note that this only happens with keys with birthdate *after* the blocks containing the spent funds which gets scanned on startup, so it's hard to test without a set seed function.

Pull request description:

  This pull request frees `keystore.h` from type alias declarations that have been declared at file scope level.

  `keystore.h` has various type aliases that have been declared ~3 - 6 years ago at file scope level, which can either be encapsulated or removed.

  Where type alias declarations are encapsulated at the appropriate scope and access level, C++11's `using` notation is used in favor of the `typedef` notation.

075429a482 Use common SetDataDir method to create temp directory in tests. (winder)

Pull request description:

  Took a stab at #12574

  Created a `getPath` method which can be used with the `TestingSetup` fixture to create a temp directory. Updated tests using temp directories to use this method.

  I tried setting up a `BOOST_GLOBAL_FIXTURE` to create a truly global path for all tests but was getting linker errors when including `boost/test/unit_test.hpp` in `test_bitcoin.cpp`. Even if I had gotten the linking to work, it looks like `make check` invokes the test binary a bunch of times, so it may not have worked anyway.

Merge #13118: RPCAuth Detection in Logs
dae0d13bbb RPCAuth Detection in Logs (Linrono)

Pull request description:

  This adds a log entry for when RPCAuth is detected.
  This keeps everything working as it currently is. I suppose it could be added as a nested if to also stop the creation of the cookie file if this would be wanted.

Matt Corallo beef7ec4be Remove useless mapRequest tracking that just effects Qt display.
I thought we had removed this a long time ago, TBH, its really
confusing feedback to users that we display whether a tx was
broadcast to immediate neighbor nodes, given that has little
indication of whether the tx propagated very far.

Merge #13386: SHA256 implementations based on Intel SHA Extensions
66b2cf1ccf Use immintrin.h everywhere for intrinsics (Pieter Wuille)
4c935e2eee Add SHA256 implementation using using Intel SHA intrinsics (Pieter Wuille)
268400d318 [Refactor] CPU feature detection logic for SHA256 (Pieter Wuille)

Pull request description:

  Based on #13191.

  This adds SHA256 implementations that use Intel's SHA Extension instructions (using intrinsics). This needs GCC 4.9 or Clang 3.4.

  In addition to #13191, two extra implementations are provided:
  * (a) A variable-length SHA256 implementation using SHA extensions.
  * (b) A 2-way 64-byte input double-SHA256 implementation using SHA extensions.

  Benchmarks for 9001-element Merkle tree root computation on an AMD Ryzen 1800X system:
  * Using generic C++ code (pre-#10821): 6.1ms
  * Using SSE4 (master, #10821): 4.6ms
  * Using 4-way SSE4 specialized for 64-byte inputs (#13191): 2.8ms
  * Using 8-way AVX2 specialized for 64-byte inputs (#13191): 2.1ms
  * Using 2-way SHA-NI specialized for 64-byte inputs (this PR): 0.56ms

  Benchmarks for 32-byte SHA256 on the same system:
  * Using SSE4 (master, #10821): 190ns
  * Using SHA-NI (this PR): 53ns

  Benchmarks for 1000000-byte SHA256 on the same system:
  * Using SSE4 (master, #10821): 2.5ms
  * Using SHA-NI (this PR): 0.51ms

Merge #13452: rpc: have verifytxoutproof check the number of txns in proof structure
d280617bf5 [qa] Add a test for merkle proof malleation (Suhas Daftuar)
ed82f17000 have verifytxoutproof check the number of txns in proof structure (Gregory Sanders)

Pull request description:

  Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/

  This change would at least allow `verifytxoutproof` to properly validate that the proof matches a known block, with known number of transactions any time after the full block is processed. This should neuter the attack entirely.

  The negative is that a header-only processed block/future syncing mode would cause this to fail until the node has imported the data required.

  related: #13451

  `importprunedfunds` needs this check as well. Can expand it to cover this if people like the idea.

Merge #13603: bitcoin-tx: Stricter check for valid integers
57889e688d bitcoin-tx: Stricter check for valid integers (Daniel Kraft)

Pull request description:

  Just calling `atoi` to convert strings to integers does not check for valid integers very thoroughly; in particular, it just ignores everything starting from the first non-numeral character.  Even a string like "foo" is fine and silently returns 0.

  This meant that `bitcoin-tx` would not fail if such a string was passed in various places where an integer is expected (like the `locktime` or an input/output index); this means that it would, for instance, silently accept a typo and interpret it in an unexpected way.

  In this change, we use `ParseInt64` for parsing strings to integers, which actually verifies that the full string is valid as number.  New tests in the `bitcoin-util-test` cover the new error paths.

  This fixes #13599.

161e8d40a4 RPC: Add new getzmqnotifications method. (Daniel Kraft)
caac39b0ac Make ZMQ notification interface instance global. (Daniel Kraft)

Pull request description:

  This adds a new RPC method `getzmqnotifications`, which returns information about all active ZMQ notification endpoints.  This is useful for software that layers on top of bitcoind, so it can verify that ZeroMQ is enabled and also figure out where it should listen.

  See #13526.

Merge #13614: doc: Update command line help for -printtoconsole and -debuglogfile (satwo)
5e362c0cf0 Fix command line help for -printtoconsole and -debuglogfile (Samuel B. Atwood)

Pull request description:

  This is a rebased version of #13589 with the changes to the 0.16.x release notes removed.

  > #13004 changed the default behavior for printtoconsole but this has not been reflected in the command line help.

  > This fixes the description of -printtoconsole to reflect this change, and also provides the user with missing information on how to explicitly disable logging to debug.log.

  > At present I have made the latter update to two separate places (-printtoconsole and -debuglogfile) because a user looking for information on how to disable logging is probably going to look in the "Debugging/Testing Options" section. Moving -debuglogfile from the "General" options category to the "Debugging/Testing" section could potentially remove the need for this redundancy but may be out of the scope of this PR.
