fae196147bae11202c0d54543dc12ba5d92ab0cc doc: Clarify that feerates are per virtual size (MarcoFalke)
fa83e95ac6f318caa38016a08fa4e402c3b05833 scripted-diff: Clarify that feerates are per virtual size (MarcoFalke)
Pull request description:
By implementing segwit, it is already clear that all feerates in Bitcoin Core are denoted in (amount/virtual size). Though, there is inconsistency, as some places use kvB, some use kB. Thus, replace all with "kvB".
See also commit 6da3afbaee5809ebf6d88efaa3958c505c2d71c7, which did the replacement for wallet RPCs.

Pull request description:
Since #9319 proposed by Gregory Maxwell and released in v0.14, peers manually added through the `-addnode` config option or using the `addnode` RPC have their own separate limit of 8 connections that does not compete with other inbound or outbound connection usage and is not subject to the limitation imposed by the `-maxconnections` option.
This PR updates the `-addnode` and `-maxconnections` config options and the `addnode` RPC help docs with this information.
`-addnode` config option help
```
$ bitcoind -h | grep -A5 addnode=
-addnode=<ip>
Add a node to connect to and attempt to keep the connection open (see
the addnode RPC help for more info). This option can be specified
multiple times to add multiple nodes; connections are limited to
8 at a time and are counted separately from the -maxconnections
limit.
$ bitcoind -h | grep -A3 maxconnections=
-maxconnections=<n>
Maintain at most <n> connections to peers (default: 125). This limit
does not apply to connections manually added via -addnode or the
addnode RPC, which have a separate limit of 8.
```
`addnode` rpc help
```
$ bitcoin-cli help addnode
addnode "node" "command"
Attempts to add or remove a node from the addnode list.
Or try a connection to a node once.
Nodes added using addnode (or -connect) are protected from DoS disconnection and are not required to be
full nodes/support SegWit as other outbound peers are (though such peers will not be synced from).
Addnode connections are limited to 8 at a time and are counted separately from the -maxconnections limit.

2e2648a9021dfbb6e17dfa81472f057dacbc34e0 crypto: Make MuHash Remove method efficient (Fabian Jahr)
Pull request description:
This is part of the coinstats index project tracked in #18000
While the review of the new UTXO set hash algorithm (MuHash) takes longer recently #19328 was merged which added the possibility to run `gettxoutsetinfo` with a specific hash type. As the first type it added `hash_type=none` which skips the hashing of the UTXO set altogether. This alone did not make `gettxoutsetinfo` much faster but it allows the use of an index for the remaining coin statistics even before a new hashing algorithm has been added. Credit to Sjors for the idea to take this intermediate step.
Features summary:
- Users can start their node with the option `-coinstatsindex` which syncs the index in the background
- After the index is synced the user can use `gettxoutsetinfo` with `hash_type=none` or `hash_type=muhash` and will get the response instantly out of the index
- The user can specify a height or block hash when calling `gettxoutsetinfo` to see coin statistics at a specific block height

d831e711cab83c70bf2ded62fe33f484844e73dd [validation] RewindBlockIndex no longer needed (Dhruv Mehta)
Pull request description:
Closes #17862
Context from [original comment](https://github.com/bitcoin/bitcoin/issues/17862#issuecomment-744285188) (minor edits):
`RewindBlockIndex()` is a mechanism to allow nodes to be upgraded after segwit activation, while still keeping their chainstate/datadir in a consistent state. It works as follows:
- A pre-segwit (i.e. v0.13.0 or older) node is running.
- Segwit activates. The pre-segwit node remains sync'ed to the tip, but is not enforcing the new segwit rules.
- The user upgrades the node to a segwit-aware version (v0.13.1 or newer).
- On startup, in `AppInitMain()`, `RewindBlockIndex()` is called. This walks the chain backwards from the tip, disconnecting and erasing blocks that from after segwit activation that weren't validated with segwit rules.
- those blocks are then redownloaded (with witness data) and validated with segwit rules.
This logic probably isn't required any more since:
- Segwit activated at height 481824, when the block chain was 130GB and the total number of txs was 250 million. Today, we're at height 667704, the blockchain is over 315GB and the total number of txs is over 600 million. Even if 20% of that added data is witness data (a high estimate), then around 150GB of transactions would need to be rewound to get back to segwit activation height. It'd probably be faster to simply validate from genesis, especially since we won't be validating any scripts before the assumevalid block. It's also unclear whether rewinding 150GB of transactions would even work. It's certainly never been tested.
- Bitcoin Core v0.13 is hardly used any more. https://luke.dashjr.org/programs/bitcoin/files/charts/software.html shows less than 50 nodes running it. The software was EOL on Aug 1st 2018. It's very unlikely that anyone is running 0.13 and will want to upgrade to 0.22.
This PR introduces `NeedsRedownload()` which merely checks for insufficiently validated segwit blocks and requests that the user restarts the node with `-reindex`. Reindexing the block files upon restart will make the node rebuild chain state and block index from the `blk*.dat` files on disk. The node won't be able to index the blocks with `BLOCK_OPT_WITNESS`, so they will be missing from the chain and be re-downloaded, with witness data.
Removing this code allows the following (done in follow-up #21090):
- removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
- in turn, that allows us to drop support for `-segwitheight=-1`, which is only supported for that test.
- that allows us to always set `NODE_WITNESS` in our local services. The only reason we don't do that is to support `-segwitheight=-1`.
- that in turn allows us to drop all of the `GetLocalServices() & NODE_WITNESS` checks inside `net_processing.cpp`, since our local services would always include `NODE_WITNESS`

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This change is move-only and can be easily reviewed with `--color-moved=dimmed_zebra`. The moves are needed to avoid duplicating common init code between different binaries (`bitcoin-node`, `bitcoin-wallet`, etc) in #10102. In #10102, each binary has it's own init file (`src/init/bitcoin-node.cpp`, `src/init/bitcoin-wallet.cpp`) so this PR moves the common code to `src/init/common.cpp`.

Pull request description:
This picks up the closed pull request #21030 and is the first step toward fixing #21220.
The basic idea is to move all disk access into a separate module with benefits:
* Breaking down the massive files init.cpp and validation.cpp into logical units
* Creating a standalone-module to reduce the mental complexity
* Pave the way to fix validation related circular dependencies
* Pave the way to mock disk access for testing, especially where it is performance critical (like fuzzing)

This just makes an additional simplification after #21366 replaced
util::Ref with std::any. It was originally suggested
https://github.com/bitcoin/bitcoin/pull/21366#issuecomment-792044351 but
delayed for a followup. It would have prevented usage bug
https://github.com/bitcoin/bitcoin/pull/21572.

Pull request description:
As described in `util/ref.h`: "_This implements a small subset of the functionality in C++17's std::any class, and **can be dropped when the project updates to C++17**_". For accessing the contained object of a `std::any` instance, a helper template function `AnyPtr` is introduced (thanks to ryanofsky).

1c25adf6d278eb1a1f018986a126d0eb8137e0ee [net] Construct addrman outside connman (John Newbery)
Pull request description:
Addrman is currently a member variable of connman. Make it a top-level component with lifetime owned by node.context, and add a reference to addrman in peerman. This allows us to eliminate some functions in connman that are simply forwarding requests to addrman, and simplifies the connman-peerman interface.
By constructing the addrman in init, we can also add parameters to the ctor, which allows us to test it better. See #20233, where we enable consistency checking for addrman in our functional tests.

52f0be3a933225429b9b59b58de4fe54c2b20a02 compat: remove memcpy -> memmove backwards compatibility alias (fanquake)
Pull request description:
In glib 2.13 memcpy was changed such that the way it copied bytes was reversed.
This caused all sorts of issues for existing software, which depended on the
existing behavior (when they should have been using memmove). See:
https://sourceware.org/bugzilla/show_bug.cgi?id=12518
https://bugzilla.redhat.com/show_bug.cgi?id=638477
Now that we require glibc 2.17+ (#17538), we should be well clear of having to
maintain our memcpy -> memmove aliasing, which was introduced in #4339.

1a6323bdbe20bdb7b1c907d8fa0333ffa88b21ff doc: update developer notes for removal of MakeUnique (fanquake)
3ba2840e7ee81341b0748c0121aedc2e9305041a scripted-diff: remove MakeUnique<T>() (fanquake)
Pull request description:
Since requiring C++17, this is just pointless abstraction. I think we should just "tear the band-aid off" and remove it. Similar to the changes happening in #21366.
Also, having a comment saying this is deprecated doesn't prevent it's usage in new code. i.e : https://github.com/bitcoin/bitcoin/pull/20946#discussion_r561949731.
The repository is fairly quiet at the moment, so any potential complaints about having to rebase should be minimal. Might as well get this over and done with.

e017a913d0d78ef0766cf73586fe7a38488e1a26 bitcoind: Add -daemonwait option to wait for initialization (Wladimir J. van der Laan)
c3e6fdee6d39d3f52dec421b48a0ac8bad5006f7 shutdown: Use RAII TokenPipe in shutdown (Wladimir J. van der Laan)
612f746a8ffa265b6877bedbbe21fcbb392f1516 util: Add RAII TokenPipe (Wladimir J. van der Laan)
Pull request description:
This adds a `-daemonwait` flag that does the same as `-daemon` except that it, from a user perspective, backgrounds the process only after initialization is complete. This is similar to the behaviour of some other software such as c-lightning.
This can be useful when the process launching bitcoind wants to guarantee that either the RPC server is running, or that initialization failed, before continuing. The exit code indicates the initialization result.
The use of the libc function `daemon()` is replaced by a custom implementation which is inspired by the [glibc implementation](https://github.com/lattera/glibc/blob/master/misc/daemon.c#L44), but which also creates a pipe from the child to the parent process for communication.
An additional advantage of having our own `daemon()` implementation is that no MACOS-specific pragmas are needed anymore to silence a deprecation warning.
TODO:
- [x] Factor out `token_read` and `token_write` to an utility, and use them in `shutdown.cpp` as well—this is exactly the same kind of communication mechanism.
- [x] RAII-ify pipe endpoints.
- [x] Improve granularity of the `configure.ac` checks. This currently still checks for the function `daemon()` which makes no sense as it's not used. It should check for individual functions such as
`fork()` and `setsid()` etc—the former being required, the second optional.
- [-] ~~Signal propagation during initialization: if say, pressing Ctrl-C during `-daemonwait` it would be good to pass this SIGINT on to the child process instead of detaching the parent process and letting the child run free.~~ This is not necessary, see https://github.com/bitcoin/bitcoin/pull/21007#issuecomment-769007341.
Future:
- Consider if it makes sense to use this in the RPC tests (there would be no more need for "is RPC ready" polling loops). I think this is out of scope for this PR.
