faec851b6e test: Simplify cs_main locks (MarcoFalke)
Pull request description:
Split out from #19556
Instead of relying on the implicit mempool global, pass a mempool pointer (which can be `0`). This helps with testing, code clarity and unlocks the features described in #19556.

da039d2a91 Remove BDB dummy databases (Andrew Chow)
0103d6434e Introduce DummyDatabase and use it in the tests (Andrew Chow)
Pull request description:
In the unit tests, we use a dummy `WalletDatabase` which does nothing and always returns true. This is currently implemented by creating a `BerkeleyDatabase` in dummy mode. This PR instead adds a `DummyDatabase` class which does nothing and never fails for use in the tests. `CreateDummyWalletDatabase` is changed to return this `DummyDatabase` and `BerkeleyDatabase` is cleaned up to remove all of the checks for `IsDummy`.
Based on `WalletDatabase` abstract class introduced in #19334

Pull request description:
Following the merge of wtxid relay in #18044, this is the first of three refactoring PRs (this one, #19610, and #19611) with no change in behavior, tightly scoped to ease review, to simplify the net processing code and improve encapsulation:
- add `CInv` transaction message helper methods, defined in the class
- use the new helpers in `net_processing.cpp` to simplify the code and improve encapsulation
Test coverage is provided by the functional p2p tests, notably (from seeing which tests failed when breaking things to test coverage) `p2p_segwit`, `p2p_tx_download`, `p2p_feefilter`, and `p2p_permissions`.

78c312c983 Replace current benchmarking framework with nanobench (Martin Ankerl)
Pull request description:
Replace current benchmarking framework with nanobench
This replaces the current benchmarking framework with nanobench [1], an
MIT licensed single-header benchmarking library, of which I am the
autor. This has in my opinion several advantages, especially on Linux:
* fast: Running all benchmarks takes ~6 seconds instead of 4m13s on
an Intel i7-8700 CPU @ 3.20GHz.
* accurate: I ran e.g. the benchmark for SipHash_32b 10 times and
calculate standard deviation / mean = coefficient of variation:
* 0.57% CV for old benchmarking framework
* 0.20% CV for nanobench
So the benchmark results with nanobench seem to vary less than with
the old framework.
* It automatically determines runtime based on clock precision, no need
to specify number of evaluations.
* measure instructions, cycles, branches, instructions per cycle,
branch misses (only Linux, when performance counters are available)
* output in markdown table format.
* Warn about unstable environment (frequency scaling, turbo, ...)
* For better profiling, it is possible to set the environment variable
NANOBENCH_ENDLESS to force endless running of a particular benchmark
without the need to recompile. This makes it to e.g. run "perf top"
and look at hotspots.

Previously having no database handle could still be considered a success
when BerkeleyDatabase and BerkeleyBatch were used for dummy database
things. With dedicated DummyDatabase and DummyBatch classes now, these
should fail.

65fb8807ac Combine BerkeleyEnvironment::Verify into BerkeleyDatabase::Verify (Andrew Chow)
Pull request description:
`BerkeleyBatch` and `BerkeleyDatabase` are kind of messy. The goal of this is to clean up them up so that they are logically separated.
`BerkeleyBatch` currently handles the creation of the `BerkeleyDatabase`'s `Db` handle. This is instead moved into `BerkeleyDatabase` and is called by `BerkeleyBatch`.
Instead of having `BerkeleyEnvironment` track each database's usage, have `BerkeleyDatabase` track this usage itself with the `m_refcount` variable that is present in `WalletDatabase`.
Lastly, instead of having each `BerkeleyEnvironment` store the fileids of the databases open in it, have a global `g_fileids` to track those fileids. We were already checking fileid uniqueness globally (by checking the fileids in every environment when opening a database) so it's cleaner to do this with a global variable.
All of these changes allow us to make `BerkeleyBatch` and `BerkeleyDatabase` no longer be friend classes.

bcfebb6d55 net: save the network type explicitly in CNetAddr (Vasil Dimov)
100c64a95b net: document `enum Network` (Vasil Dimov)
Pull request description:
(chopped off from https://github.com/bitcoin/bitcoin/pull/19031 to ease review)
Before this change, we would analyze the contents of `CNetAddr::ip[16]`
in order to tell which type is an address. Change this by introducing a
new member `CNetAddr::m_net` that explicitly tells the type of the
address.
This is necessary because in BIP155 we will not be able to tell the
address type by just looking at its raw representation (e.g. both TORv3
and I2P are "seemingly random" 32 bytes).
As a side effect of this change we no longer need to store IPv4
addresses encoded as IPv6 addresses - we can store them in proper 4
bytes (will be done in a separate commit). Also the code gets
somewhat simplified - instead of
`memcmp(ip, pchIPv4, sizeof(pchIPv4)) == 0` we can use
`m_net == NET_IPV4`.

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
In the assumeutxo implementation draft (#15056), once a UTXO snapshot is loaded, a new chainstate object is created after initialization. This means that we have to reclaim some of the cache that we've allocated to the original chainstate (per `dbcache=`) to repurpose for the snapshot chainstate.
Furthermore, it makes sense to have different cache allocations depending on which chainstate is more active. While the snapshot chainstate is working to get to the network tip (and the background validation chainstate is idle), it makes sense that the snapshot chainstate should have the majority of cache allocation. And contrariwise once the snapshot has reached network tip, most of the cache should be given to the background validation chainstate.
This set of changes (detailed in the commit messages) allows us to dynamically resize the various coins caches. None of the functionality introduced here is used at the moment, but will be in the next AU PR (which introduces `ActivateSnapshot`).
`ChainstateManager::MaybeRebalanceCaches()` defines the (somewhat normative) cache allocations between the snapshot and background validation chainstates. I'd be interested in feedback if anyone has thoughts on the proportions I've set there.

Rather than just using it on Linux and NetBSD, use `fdatasync()` based
on whether it's available. i.e it is available in newer versions
of FreeBSD (11.1 and later).
This also aligns our code more closely with what is being done in leveldb.

fa5979d12f rpc: Avoid useless mempool query in gettxoutproof (MarcoFalke)
fa1f7f28cb rpc: Style fixups in gettxoutproof (MarcoFalke)
Pull request description:
`GetTransaction` implicitly and unconditionally asks the mempool global for a transaction. This is problematic for several reasons:
* `gettxoutproof` is for on-chain txs only and asking the mempool for on-chain txs is confusing and minimally wasteful
* Globals are confusing and make code harder to test with unit tests
Fix both issues by passing in an optional mempool. This also helps with #19556

- Make const things const.
- Replace conditional return with assert.
- Don't log the peer's IP address.
- Log the name Misbehaving directly instead of relying on __func__.
Misbehaving() could optionally take a debug string for printing to the
log file. Make this mandatory and always provide the string.
A couple of additional minor changes:
- remove the unnecessary forward declaration of Misbehaving()
- don't include the nodeid or newline in the passed debug message.
Misbehaving() adds these itself.

The motivation for this PR is to reduce the scope of cs_main locking in misbehavior logic. It is the first set of commits from a larger branch to move the misbehavior data out of CNodeState and into a new struct that doesn't take cs_main.
There are some very minor behavior changes in this branch, such as:
- Not checking for discouragement/disconnect in `ProcessMessages()` (and instead relying on the following check in `SendMessages()`)
- Checking for discouragement/disconnect as the first action in `SendMessages()` (and not doing ping message sending first)
- Continuing through `SendMessages()` if `MaybeDiscourageAndDisconnect()` doesn't disconnect the peer (rather than dropping out of `SendMessages()`
