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.
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.

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.

87fe292d89 doc: Mention disabling BIP61 in bips.md (Wladimir J. van der Laan)
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.

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).

2885c131b6 Qt: use [default wallet] as name for wallet with no name (Jonas Schnelli)
Pull request description:
Loading a wallet from a state where only the default wallet was active results in using an empty string for the initial/default wallet name.
This is a GUI only quick-fix that overrides wallet(s) with name "" to "[default wallet]". Does not affect `getwalletinfo` or `listwallets`.
Also, unsure if it should be fixed at a deeper level and if – instead of [default wallet] – it should use `wallet.dat` (the filename of the default wallet).

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!

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.

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.

9aac9f90d5 replace modulus with FastMod (Martin Ankerl)
Pull request description:
Not sure if this is optimization is necessary, but anyway I have some spare time so here it is. This replaces the slow modulo operation with a much faster 64bit multiplication & shift. This works when the hash is uniformly distributed between 0 and 2^32-1. This speeds up the benchmark by a factor of about 1.3:
```
RollingBloom, 5, 1500000, 3.73733, 4.97569e-07, 4.99002e-07, 4.98372e-07 # before

```
Be aware that this changes the internal data of the filter, so this should probably
not be used for CBloomFilter because of interoperability problems.

Pull request description:
Originally this PR was just to add tests around concurrency in block validation - those tests seem to have uncovered another bug in ActivateBestChain - this now fixes that bug and adds tests.
ActivateBestChain (invoked after a new block is validated) proceeds in steps - acquiring and releasing cs_main while incrementally disconnecting and connecting blocks to sync to the most work chain known (FindMostWorkChain()). Every time cs_main is released the result of FindMostWorkChain() can change - but currently that value is cached across acquisitions of cs_main and only refreshed when an invalid chain is explored. It needs to be refreshed every time cs_main is reacquired. The test added in 6094ce7304 will occasionally fail without the commit fixing this issue 26bfdbaddb
Original description below
--
After a bug discovered where UpdatedBlockTip() notifications could be triggered out of order (#12978), these unit tests check certain invariants about these signals.
The scheduler test asserts that a SingleThreadedSchedulerClient processes callbacks fully and sequentially.
The block validation test generates a random chain and calls ProcessNewBlock from multiple threads at random and in parallel. ValidationInterface callbacks verify that the ordering of BlockConnected BlockDisconnected and UpdatedBlockTip events occur as expected.
