Using the given address, `getaddressinfo` will look up which `DescriptorScriptPubKeyMan` can be used to produce that address. It will then return the descriptor for that `DescriptorScriptPubKeyMan` in the `parent_desc` field. The descriptor will be in a normalized form where the xpub at the last hardened step is derived so that the descriptor can be imported to other wallets. Tests are added to check that the correct descriptor is being returned for the wallet's addresses and that these descriptors can be imported and used in other wallets. As part of this PR, a `ToNormalizedString` function is added to the descriptor classes. This really only has an effect on `BIP32PubkeyProvider`s that have hardened derivation steps. Tests are added to check that normalized descriptors are returned.

060a2a64d40d75fecb60b7d2b9946a67e46aa6fc ci: remove boost thread installation (fanquake) 06e1d7d81d5a56d136c6fc88f09a2b0654a164f9 build: don't build or use Boost Thread (fanquake) 7097add83c8596f81be9edd66971ffd2486357eb refactor: replace Boost shared_mutex with std shared_mutex in sigcache (fanquake) 8e55981ef834490c438436719f95cbaf888c4914 refactor: replace Boost shared_mutex with std shared_mutex in cuckoocache tests (fanquake) Pull request description: This replaces `boost::shared_mutex` and `boost::unique_lock` with [`std::shared_mutex`](https://en.cppreference.com/w/cpp/thread/shared_mutex) & [`std::unique_lock`](https://en.cppreference.com/w/cpp/thread/unique_lock). Even though [some concerns were raised](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) in #16684 with regard to `std::shared_mutex` being unsafe to use across some glibc versions, I still think this change is an improvement. As I mentioned in #21022, I also think trying to restrict standard library feature usage based on bugs in glibc is not only hard to do, but it's not currently clear exactly how we do that in practice (does it also extend to patching out use in our dependencies, should we be implementing more runtime checks for features we are using, when do we consider an affected glibc "old enough" not to worry about? etc). If you take a look through the [glibc bug tracker](https://sourceware.org/bugzilla/describecomponents.cgi?product=glibc) you'll no doubt find plenty of (active) bug reports for standard library code we already using. Obviously not to say we shouldn't try and avoid buggy code where possible. Two other points: [Cory mentioned in #21022](https://github.com/bitcoin/bitcoin/pull/21022#issuecomment-769274179): > It also seems reasonable to me to worry that boost hits the same underlying glibc bug, and we've just not happened to trigger the right conditions yet. Moving away from Boost to the standard library also removes the potential for differences related to Boosts configuration. Boost has multiple versions of `shared_mutex`, and what you end up using, and what it's backed by depends on: * The version of Boost. * The platform you're building for. * Which version of `BOOST_THREAD_VERSION` is defined: (2,3,4 or 5) default=2. (see [here](https://www.boost.org/doc/libs/1_70_0/doc/html/thread/build.html#thread.build.configuration) for some of the differences). * Is `BOOST_THREAD_V2_SHARED_MUTEX` defined? (not by default). If so, you might get the ["less performant, but more robust"](https://github.com/boostorg/thread/issues/230#issuecomment-475937761) version of `shared_mutex`. A lot of these factors are eliminated by our use of depends, but users will have varying configurations. It's also not inconceivable to think that a distro, or some package manager might start defining something like `BOOST_THREAD_VERSION=3`. Boost tried to change the default from 2 to 3 at one point. With this change, we no longer use Boost Thread, so this PR also removes it from depends, the build system, CI etc. Previous similar PRs were #19183 & #20922. The authors are included in the commits here. Also related to #21022 - pthread sanity checking.

This adds a `TxoutType::WITNESS_V1_TAPROOT` for P2TR outputs, and permits spending them in standardness rules. No corresponding `CTxDestination` is added for it, as that isn't needed until we want wallet integration.

The commit "Add additional check for P2SH before adding extra wrapper" also adds an additional check that the scriptPubKey is a P2SH before auto-wrapping the witness script. We shouldn't wrap the witness script if not. Note: #16251 is even better than this check, please review that.

signing code (sipa) dca28634d779c775678cba402a85fe5bb9b3a5a9 test: ensure OP_1NEGATE satisfies BIP62 minimal push rule (Jon Atack) e629d07199b83f4ad313b23a94c9016e3276c52a Do not turn OP_1NEGATE in scriptSig into 0x0181 in signing code (Pieter Wuille) Pull request description: A rebase of #13084 which additionally modifies the test code (unaddressed in the original, assuming sipa is too busy to deal with this at the moment). Relatively simple bugfix so it'd be good to have merged soon. Turning OP_1NEGATE into 0x0181 results in a larger-than-necessary data push instead of just actually using the OP_1NEGATE opcode (0x4f). This fails the minimal push rule of BIP 62 and makes the result non-standard.
