Merge #13112: Throw an error for unknown args
903055730b Test gArgs erroring on unknown args (Andrew Chow)
4f8704d57f Give an error and exit if there are unknown parameters (Andrew Chow)
174f7c8080 Use a struct for arguments and nested map for categories (Andrew Chow)

Pull request description:

  Following #13190, gArgs is aware of all of the command line arguments. This PR has gArgs check whether the arguments provided are actually valid arguments. When an unknown argument is encountered, an error is printed to stderr and the program exist.

  Since gArgs is used for everything that has command line arguments, `bitcoind`, `bitcoin-cli`, `bitcoin-qt`, `bitcoin-tx`, and `bench_bitcoin` are all effected by this change and all now have the same argument checking behavior.

  Closes #1044

Merge #13252: Wallet: Refactor ReserveKeyFromKeyPool for safety
4b62bdf513 Wallet: Refactor ReserveKeyFromKeyPool for safety (Ben Woosley)

Pull request description:

  ReserveKeyFromKeyPool's previous behaviour is to set nIndex to -1 if the keypool is
  empty, OR throw an exception for technical failures. Instead, we now return false
  if the keypool is empty, true if the operation succeeded.

  This is to make failure more easily detectable by calling code.

174f7c8080 Use a struct for arguments and nested map for categories
Instead of a single map with the category and name as the key,
make m_available_args contain maps. The key will be the category and
the value is a map which actually contains the arguments for that
category. The nested map's key is the argument name, while the value
is a struct that contains the help text and whether the argument is
a debug only argument.

Merge #13194: Remove template matching and pseudo opcodes
c814e2e7e8 Remove template matching and pseudo opcodes (Pieter Wuille)

Pull request description:

  The current code contains a rather complex script template matching engine, which is only used for 3 particular script types (P2PK, P2PKH, multisig). The first two of these are trivial to match for otherwise, and a specialized matcher for multisig is both more compact and more efficient than a generic one.

  The goal is being more flexible, so that for example larger standard multisigs inside SegWit outputs are easier to implement.

  As a side-effect, it also gets rid of the pseudo opcodes hack.

Merge #13341: Stop translating command line options
3d4fa83587 Stop translating command line options (Wladimir J. van der Laan)

Pull request description:

  Many options are extremely technical, and refer internals, making it difficult to translate usefully. This came up in discussion of e.g.  #10949. If a message is not understood by translators (which are typically end-users, not developers) they'll either translate it literally, making it harder to understand instead of easier, with the added drawback of the user no longer being able to google it.

  Also the translation was only working for bitcoin-qt as with the console programs, there is no translation backend. So it was injecting never-used translation messages for bitcoin-cli, -tx.

  For these reasons, stop translating options help completely. This should not affect the output **in any way** \* except for bitcoin-qt when a non-English language is configured in the locale.

  This implements #10962.

  \*) I checked this, but please do verify this.

Merge #13281: test: Move linters to test/lint, add readme
fa3c910bfe test: Move linters to test/lint, add readme (MarcoFalke)

Pull request description:

  This moves the checks and linters from `devtools` to a subfolder in `test`. (Motivated by my opinion that the dev tools are mostly for generating code and updating the repo whereas the linters are read-only checks.)

  Also, adds a readme to clarify that checks and linters are only meant to prevent bugs and user facing issues, not merely stylistic preference or inconsistencies. (This is motivated by the diversity in developers and work flows as well as existing code styles. It would be too disruptive to change all existing code to a single style or too burdensome to force all developers to adhere to a single style. Also note that our style guide is changing, so locking in at the wrong style "too early" would only waste resources.)

fe16dd8226 net: Add option `-enablebip61` to configure sending of BIP61 notifications (Wladimir J. van der Laan)

Pull request description:

  This commit adds a boolean option `-peersendreject`, defaulting to `1`, that can be used to disable the sending of [BIP61](https://github.com/bitcoin/bips/blob/master/bip-0061.mediawiki) `reject` messages. This functionality has been requested for various reasons:

  - security (DoS): reject messages can reveal internal state that can be used to target certain resources such as the mempool more easily.

  - bandwidth: a typical node sends lots of reject messages; this counts against upstream bandwidth. Also the reject messages tend to be larger than the message that was rejected.

  On the other hand, reject messages can be useful while developing client software (I found them indispensable while creating bitcoin-submittx), as well as for our own test cases, so whatever the default becomes on the long run, IMO the functionality should be retained as option. But that's a discussion for later, for now it's simply a node operator decision.

  Also adds a RPC test that checks the functionality.

Merge #13273: Qt/Bugfix: fix handling default wallet with no name
13c3a659c0 Qt/Bugfix: fix handling default wallet with no name (João Barbosa)

Pull request description:

  If one loads a wallet via RPC (`loadwallet w2`), then select w2, select back to the default wallet (which is an empty string), that default wallet cannot be access through the RPC console because the current code only points to the wallet endpoint if the wallet name is not empty.

  This is a quick fix that reenables accessing the default wallet in case an additional wallet has been loaded.

  Using "" for the default wallet may not be ideal in other cases and it may make more sense to change it at a deeper level (wallet.cpp). See discussion here which where the reasons for the current behaviour in master:

4e91820531 Make IsMine stop distinguishing solvable/unsolvable (Pieter Wuille)
6d714c3419 Make coincontrol use IsSolvable to determine solvability (Pieter Wuille)

Pull request description:

  Our current `IsMine` logic does several things with outputs:
  * Determine "spendability" (roughly corresponding to "could we sign for this")
  * Determine "watching" (is this an output directly or indirectly a watched script)
  * Determine invalidity (is this output definitely not legally spendable, detecting accidental uncompressed pubkeys in witnesses)
  * Determine "solvability" (would we be able to sign for this ignoring the fact that we may be missing some private keys).

  The last item (solvability) is mostly unrelated and only rarely needed (there is just one instance, inside the wallet's coin control logic). This PR changes that instance to use the separate `IsSolvable` function, and stop `IsMine` from distinguishing between solvable and unsolvable.

  As an extra, this also simplifies the `IsMine` logic and adds some extra checks (which wouldn't be hit unless someone adds already invalid scripts to their wallet).

Merge #13284: gui: fix visual "overflow" of amount input.
5f3cbde9de Increased max width of amount field to prevent number overflow bug. (Brandon Ruggles)

Pull request description:

  Fixes #13231.

  I was able to reproduce this bug within my own Fedora 27 VM. Following @jonasschnelli's advice, I first tried to change `setAlignment(Qt::AlignRight);` to `setAlignment(Qt::AlignLeft);`, however, I realized that this wouldn't fix the underlying overflow problem, as it would only make it easier to see the most significant digits under certain scenarios. The reason for the overflow is that Fedora uses plus and minus buttons on the Qt spin box class, rather than up and down arrows, which is what happens on **most** other operating systems. These plus and minus buttons take up more width, and therefore provide less space for text.

  The solution I went with was the second suggestion by @jonasschnelli, which was to just increase the maximum width of the amount box. After some experimentation, 240 seemed to be the smallest max width that would allow as many digits as one would want in the amount box without overflow, even with the plus and minus buttons in Fedora.

  Please let me know if there are any issues with this PR and I will work to fix them. Thank you!

Merge #13291: test: Don't include torcontrol.cpp into the test file
97c112d4ca Declare TorReply parsing functions in torcontrol_tests (Ben Woosley)

Pull request description:

  These methods are standalone string parsing methods which were included
  into test via an include of torcontrol.cpp, which is bad practice.

  ~~Splitting them out reveals that they were the only torcontrol.cpp
  methods under test, so the test file is renamed tor_reply_tests.cpp.~~

  Introduced in #10408

Pull request description:

  `random.cpp` needs to explicitly include `utilstrencodings.h` to get `ARRAYLEN`. This fixes the FreeBSD build.

Merge #13063: Use shared pointer to retain wallet instance
80b4910f7d wallet: Use shared pointer to retain wallet instance (João Barbosa)

Pull request description:

  Currently there are 3 places where it makes sense to retain a wallet shared pointer:
   - `vpwallets`;
   - `interfaces::Wallet` interface instance - used by the UI;
   - wallet RPC functions - given by `GetWalletForJSONRPCRequest`.

  The way it is now it is possible to have, for instance, listunspent RPC and in parallel unload the wallet (once #13111 is merged) without blocking. Once the RPC finishes, the shared pointer will release the wallet.

  It is also possible to get all existing wallets without blocking because the caller keeps a local list of shared pointers.

  This is mostly relevant for wallet unloading.

  This PR replaces #11402.

Merge #13151: net: Serve blocks directly from disk when possible
0bf431870e net: Serve blocks directly from disk when possible (Wladimir J. van der Laan)

Pull request description:

  In `ProcessGetBlockData`, send the block data directly from disk if type MSG_WITNESS_BLOCK is requested. This is a valid shortcut as the on-disk format matches the network format.

  This is expected to increase performance because a deserialization and subsequent serialization roundtrip is avoided.

Merge #13011: Cache witness hash in CTransaction
fac1223a56 Cache witness hash in CTransaction (MarcoFalke)
faab55fbb1 Make CMutableTransaction constructor explicit (MarcoFalke)

Pull request description:

  This speeds up:
  * compactblocks (v2)
  * ATMP
  * validation and miner (via `BlockWitnessMerkleRoot`)
  * sigcache (see also unrelated #13204)
  * rpc and rest (nice, but irrelevant)

  This presumably slows down rescan, which uses a `CTransaction` and its `GetHash`, but never uses the `GetWitnessHash`. The slow down is proportional to the number of witness transactions in the rescan window. I.e. early in the chain there should be no measurable slow down. Later in the chain, there should be a slow down, but acceptable given the speedups in the modules mentioned above.
