The fuzzer goes through a sequence of operations that get applied to both a
real stack of CCoinsViewCache objects, and to simulation data, comparing
the two at the end.

d35595a78a4a6cae72d3204c1ec3f82f77a10d56 addrman: add function to return size by network and table (Martin Zumsande)
Pull request description:
AddrMan currently doesn't track the number of its entries by network, it only knows the total number of addresses. This PR makes AddrMan keep track of these numbers, which would be helpful for multiple things:
1. Allow to specifically add fixed seeds to AddrMan of networks where we don't have any addresses yet - even if AddrMan as a whole is not empty (partly fixing #26035). This is in particular helpful if the user abruptly changes `-onlynet` settings (such that addrs that used to be reachable are no longer and vice versa), in which case they currently could get stuck and not find any outbound peers. The second commit of this PR implements this.
1. (Future work): Add logic for automatic connection management with respect to networks - such as making attempts to have at least one connection to each reachable network as suggested [here](https://github.com/bitcoin/bitcoin/issues/26035#issuecomment-1249420209). This would involve requesting an address from a particular network from AddrMan, and expanding its corresponding function `AddrMan::Select()` to do this requires internal knowledge of the current number of addresses for each network and table to avoid getting stuck in endless loops.
1. (Future work): Perhaps display the totals to users. At least I would find this helpful to debug, the existing option (`./bitcoin-cli -addrinfo`) is rather indirect by doing the aggregation itself in each call, doesn't distinguish between new and tried, and being based on `AddrMan::GetAddr()` it's also subject to a quality filter which we probably don't want in this spot.

The functionality of the old size() is covered by the new Size()
when no arguments are specified, so this does not change behavior.

Pull request description:
This was done in the context of https://github.com/bitcoin/bitcoin/pull/25284 , but I think it also makes sense standalone.
The basic idea is that serialization type should not be initialized when it is not needed. Same for the serialization version.
So do this here for `DataStream`. `CDataStream` remains in places where it is not yet possible.

a4fe09973aa82210b98dcb4e4e9f11ef59780f9b txorphanage: index workset by originating peer (Anthony Towns)
Pull request description:
We currently process orphans by assigning them to the peer that provided a missing parent; instead assign them to the peer that provided the orphan in the first place. This prevents a peer from being able to marginally delay another peer's transactions and also simplifies the internal API slightly. Because we're now associating orphan processing with the peer that provided the orphan originally, we no longer process orphans immediately after receiving the parent, but defer until a future call to `ProcessMessage`.
Based on #26295

Pull request description:
Now that libsecp256k1 has a release (https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-December/021271.html), update the subtree to match it.
The changes themselves are not very impactful for Bitcoin Core, but include:
* It's no longer needed to specify whether contexts are for signing or verification or both (all contexts support everything), so make use of that in this PR.
* Verification operations can use the static context now, removing the need for some infrastructure in pubkey.cpp to make sure a context exists.
* Most modules are now enabled by default, so we can drop explicit enabling for them.
* CI improvements (in particular, MSVC and more recent MacOS)
* Introduction of an internal int128 type, which has no effect for GCC/Clang builds, but enables 128-bit multiplication in MSVC, giving a ~20% speedup there (but still slower than GCC/Clang).
* Release process changes (process documentation, changelog, ...).

Both methods do the same thing, so simplify to having just one.
`ToString()` is too generic in this case and it is unclear what it does,
given that there are similar methods:
`ToStringAddr()` (inherited from `CNetAddr`),
`ToStringPort()` and
`ToStringAddrPort()`.
Both methods do the same thing, so simplify to having just one.
Further, `CService` inherits `CNetAddr` and `CService::ToString()`
overrides `CNetAddr::ToString()` but the latter is not virtual which
may be confusing. Avoid such a confusion by not having non-virtual
methods with the same names in inheritance.
"IP" stands for "Internet Protocol".
"IP address" is sometimes shortened to just "IP" or "address".
However, Tor or I2P addresses are not "IP addresses", nor "IPs".
Thus, use "Addr" instead of "IP" for addresses that could be IP, Tor or
I2P addresses:
`CService::ToStringIPPort()` -> `CService::ToStringAddrPort()`
`CNetAddr::ToStringIP()` -> `CNetAddr::ToStringAddr()`

The chance that the fuzzer is able to guess a valid onion address is probably slim, as they are Base32 encoded and include a checksum. Right now, any target using `ConsumeNetAddr` would have a hard time uncovering bugs that require valid onion addresses as input.
This PR makes `ConsumeNetAddr` produce valid onion addresses by using the 32 bytes given by the fuzzer as the pubkey for the onion address and forming a valid address according to the torv3 spec.
