2c03cec2ff ci: Build bitcoin-chainstate (Carl Dong)
095aa6ca37 build: Add example bitcoin-chainstate executable (Carl Dong)
Pull request description:
Part of: #24303
This PR introduces an example/demo `bitcoin-chainstate` executable using said library which can print out information about a datadir and take in new blocks on stdin.
Please read the commit messages for more details.
-----
#### You may ask: WTF?! Why is `index/*.cpp`, etc. being linked in?
This PR is meant only to capture the state of dependencies in our consensus engine as of right now. There are many things to decouple from consensus, which will be done in subsequent PRs. Listing the files out right now in `bitcoin_chainstate_SOURCES` is purely to give us a clear picture of the task at hand, it is **not** to say that these dependencies _belongs_ there in any way.
### TODO
1. Clean up `bitcoin-chainstate.cpp`
It is quite ugly, with a lot of comments I've left for myself, I should clean it up to the best of my abilities (the ugliness of our init/shutdown might be the upper bound on cleanliness here...)

...to make sure that the linker errors that arise from coupling
regressions are caught by CI.
Adding to the "no wallet" ci job as suggested by MarcoFalke.
The bitcoin-chainstate executable serves to surface the dependencies
required by a program wishing to use Bitcoin Core's consensus engine as
it is right now.
More broadly, the _SOURCES list serves as a guiding "North Star" for the
libbitcoinkernel project: as we decouple more and more modules of the
codebase from our consensus engine, this _SOURCES list will grow shorter
and shorter. One day, only what is critical to our consensus engine will
remain. Right now, it's "the minimal list of files to link in to even
use our consensus engine".
[META] In a future commit the libbitcoinkernel library will be extracted
from bitcoin-chainstate, and the libbitcoinkernel library's
_SOURCES list will be the list that we aim to shrink.

Pull request description:
This PR:
1. Coalesce the Chainstate loading sequence between `AppInitMain` and `*TestingSetup` (which makes it more tested)
2. Makes the Chainstate loading sequence reusable in preparation for future work extracting out our consensus engine.
Code-wise, this PR:
1. Extracts `AppInitMain`'s Chainstate loading sequence into a `::LoadChainstateSequence` function
2. Makes this `::LoadChainstateSequence` function reusable by
1. Decoupling it from various concepts (`ArgsManager`, `uiInterface`, etc)
2. Making it report errors using an `enum` rather than by setting a `bilingual_str`
3. Makes `*TestingSetup` use this new `::LoadChainstateSequence`
Reviewers: Aside from commentary, I've also included `git diff` flags of interest in the commit messages which I hope will aid review!

b884ababc2 rpc: move Ensure* helpers to server_util.h (Sjors Provoost)
Pull request description:
This adds an RPC method to fetch a block directly from a peer. This can used to fetch stale blocks with lower proof of work that are normally ignored by the node (`headers-only` in `getchaintips`).
Usage:
```
bitcoin-cli getblockfrompeer HASH peer_n
```
Closes#20155
Limitations:
* you have to specify which peer to fetch the block from
* the node must already have the header

and are not modified in the sequence
- fPruneMode, despite being a global, is only modified in
AppInitParameterInteraction, long before LoadChainstate is called

68e5aafde3 build: add `--enable-lto` configuration option (fanquake)
Pull request description:
It's been 5 years since using LTO was first suggested for use when building Bitcoin Core, and it's time to revisit it again. Compilers, and their LTO implementations, have matured, and Bitcoin Core has come a long way in terms of pruning dependencies which may have proved troublesome (i.e Boost previously had issues when using LTO). We'll have even less Boost code after moving to `std::filesystem` (#20744).
Experimenting with LTO came up on IRC last night:
> sipa: jamesob: i'm interested in knowing whether "-flto" and/or "-fdata-sections -ffunction-sections -Wl,--gc-sections" are possible/beneficial with our current compiler suite; what would be a good way to have your test infrastructure benchmark things?
So this PR just adds the bare minimum to make it easier to configure, compile and perform some bench-marking using `-flto`. This PR doesn't do anything depends wise, however if we decide this is what we want to do, I'll expand the changes here.
I had previously had a PR open (#18605) to perform link time garbage collection (`-ffunction-sections -fdata-sections` & `-Wl,--gc-sections`), however moving straight to using LTO would be preferable.
Note that our minimum required set of compilers, GCC 8.1 and Clang 7, all support the `-flto` option.
Related #18579.
Previous discussion: #10616, #14277.
Previous related PRs: #10800 (`-flto`), #16791 (ThinLTO).

Current CWalletTx state representation makes it possible to set
inconsistent states that won't be handled correctly by wallet sync code
or serialized & deserialized back into the same form.
For example, it is possible to call setConflicted without setting a
conflicting block hash, or setConfirmed with no transaction index. And
it's possible update individual m_confirm and fInMempool data fields
without setting an overall consistent state that can be serialized and
handled correctly.
Fix this without changing behavior by using std::variant, instead of an
enum and collection of fields, to represent sync state, so state
tracking code is safer and more legible.
This is a first step to fixing state tracking bugs

A few more build issues came up (and have been fixed) since, and after discussing with sipa it was decided I would open a PR to shepherd any final changes through.
> This adds a `src/minisketch` subtree, taken from the master branch of https://github.com/sipa/minisketch, to prepare for Erlay implementation (see #21515). It gets configured for just supporting 32-bit fields (the only ones we're interested in in the context of Erlay), and some code on top is added:
> * A very basic unit test (just to make sure compilation & running works; actual correctness checking is done through minisketch's own tests).
> * A wrapper in `minisketchwrapper.{cpp,h}` that runs a benchmark to determine which field implementation to use.
Only changes since my last update to the branch in the previous PR have been rebasing on master and fixing an issue with a header in an introduced file.

fac303c504 refactor: Remove unused MakeUCharSpan (MarcoFalke)
Pull request description:
To avoid having all files at the top level `./src` directory, start moving them to their respective sub directory according to https://github.com/bitcoin/bitcoin/issues/15732.
`bloom` currently depends on libconsensus (`CTransaction`, `CScript`, ...) and it is currently located in the libcommon. Thus, move it to `src/common/`. (libutil in `src/util/` is for stuff that doesn't depend on libconsensus).

17ae2601c7 build: remove build stubs for external leveldb (Cory Fields)

0f95247246 Integrate univalue into our buildsystem (Cory Fields)
9b49ed656f Squashed 'src/univalue/' changes from 98fadc0909..a44caf65fe (fanquake)
Pull request description:
This PR more tightly integrates building Univalue into our build system. This follows the same approach we use for [LevelDB](https://github.com/bitcoin-core/leveldb/), ([`Makefile.leveldb.include`](https://github.com/bitcoin/bitcoin/blob/master/src/Makefile.leveldb.include)), and [CRC32C](https://github.com/bitcoin-core/crc32c) ([`Makefile.crc32c.include`](https://github.com/bitcoin/bitcoin/blob/master/src/Makefile.crc32c.include)), and will be the same approach we use for [minisketch](https://github.com/sipa/minisketch); see #23114.
This approach yields a number of benefits, including:
* Faster configuration due to one less subconfigure being run during `./configure` i.e 22s with this PR vs 26s
* Faster autoconf i.e 13s with this PR vs 17s
* Improved caching
* No more issues with compiler flags i.e https://github.com/bitcoin/bitcoin/pull/12467
* More direct control means we can build exactly the objects we want
There might be one argument against making this change, which is that builders should have the option to use "proper shared/system libraries". However, I think that falls down for a few reasons. The first being that we already don't support building with a number of system libraries (secp256k1, leveldb, crc32c); some for good reason. Univalue is really the odd one out at the moment.
Note that the only fork of Core I'm aware of, that actively patches in support for using system libs, also explicitly marks them as ["DANGEROUS"](a886811721/configure.ac (L1430)) and ["NOT SUPPORTED"](a886811721/configure.ac (L1312)). So it would seem they exist more to satisfy a distro requirement, as opposed to something that anyone should, or would actually use in practice.
PRs like #22412 highlight the "issue" with us operating with our own Univalue fork, where we actively fix bugs, and make improvements, when upstream (https://github.com/jgarzik/univalue) may not be taking those improvements, and by all accounts, is not currently actively maintained. Bitcoin Core should not be hamstrung into not being able to fix bugs in a library, and/or have to litter our source with "workarounds", i.e #22412, for bugs we've already fixed, based on the fact that an upstream project is not actively being maintained. Allowing builders to use system libs is really only exacerbating this problem, with little benefit to our project. Bitcoin Core is not quite like your average piece of distro packaged software.
There is the potential for us to give the same treatment to libsecp256k1, however it seems doing that is currently less straightforward.

Presumably these stubs indicate to packagers that external leveldb is meant to
be supported in some way. It is not. Remove the stubs to avoid sending any
mixed messages.
This addresses issues like the one in #12467, where some of our compiler flags
end up being dropped during the subconfigure of Univalue. Specifically, we're
still using the compiler-default c++ version rather than forcing c++17.
We can drop the need subconfigure completely in favor of a tighter build
integration, where the sources are listed separately from the build recipes,
so that they may be included directly by upstream projects. This is
similar to the way leveldb build integration works in Core.
Core benefits of this approach include:
- Better caching (for ex. ccache and autoconf)
- No need for a slow subconfigure
- Faster autoconf
- No more missing compile flags
- Compile only the objects needed
There are no benefits to Univalue itself that I can think of. These changes
should be a no-op there, and to downstreams as well until they take advantage
of the new sources.mk.
This also removes the option to use an external univalue to avoid similar ABI
issues with mystery binaries.

Pull request description:
Introduce the pimpl pattern for AddrMan to separate the implementation details from the externally used object representation. This reduces compile-time dependencies and conceptually clarifies AddrMan's interface from the implementation specifics.
Since the unit & fuzz tests currently rely on accessing AddrMan internals, this PR introduces addrman_impl.h, which is exclusively imported by addrman.cpp and test files.
