Pull request description:
This PR adjusts the two issues I encountered while developing a tool that converts RPCHelpMan objects into bindings for other language(s).
The first is in createrawtransaction, where the address part, e.g. bc1qabc in
> createrawtransaction '[]' '[{"bc1qabc": 1.0}]'
is declared as a `Type::OBJ`, when in reality it should be a `Type::OBJ_USER_KEYS`, defined as such:
5925f1e652/src/rpc/util.h (L126)
(coincidentally, this is the first and only (afaict) usage of this `RPCArg::Type`).
The second is in the `listaddressgroupings` RPC, which returns an array of arrays of arrays, where the innermost one is a tuple-thingie with an optional 3rd item; this is an `ARR_FIXED`, not an `ARR`.

fabb6dfe6e734eadd91448122f2ce8c1612c39a6 script: Replace address-of idiom with vector data() method (Guido Vranken)
Pull request description:
The main theme of this refactor is to replace `&foo[0]` with `foo.data()`.
The first commit is taken from #21781 with the rationale:
* In CSignatureCache::ComputeEntryECDSA, change the way a vector pointer is resolved to prevent invoking undefined behavior if the vector is empty.
The other commits aim to remove all `&foo[0]`, where `foo` is any kind of byte representation. The rationale:
* Sometimes alternative code without any raw data pointers is easier to read (refer to the respective commit message for details)
* If the raw data pointer is needed, `foo.data()` should be preferred, as pointed out in the developer notes. This addresses the instances that have been missed in commit 592404f03f2b734351d734f0c9ca1fdce997321b, and https://github.com/bitcoin/bitcoin/pull/9804

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.

ea269c7ef1a65960d680f405de21708ba477ecce contrib: parse I2P addresses in generate-seeds.py (Jon Atack)
Pull request description:
Follow-up to #21560 that updated the fixed seeds infra for BIP155 addresses and then added Tor v3 ones:
- Update contrib/generate-seeds.py to parse I2P addresses
- Add a few I2P nodes to contrib/seeds/nodes_main.txt
- Run generate-seeds.py and add the I2P seeds to chainparamsseeds.h
Reviewers, see contrib/seeds/README.md for more info and feel free to use the following CLI one-liner to check for and propose additional seeds for contrib/seeds/nodes_main.txt. You can also see how many I2P peers your node knows with cli -addrinfo.
```rake
bitcoin-cli getnodeaddresses 0 | jq '.[] | (select(.address | contains(".b32.i2p"))) | .address' | sort
```
I verified the I2P addresses are correctly BIP155-serialized/deserialized by building with all seeds removed from chainparamsseeds.h except those added here, restarting with `-datadir=newdir -dnsseed=0` and running rpc ` getnodeaddresses 0` that initially returns only the new I2P addresses.

9096b13a4764873511b65f32a005ce4738b0d81c net: remove unnecessary check of CNode::cs_vSend (Vasil Dimov)
Pull request description:
It is not possible to have a node in `CConnman::vNodesDisconnected` and
its reference count to be incremented - all `CNode::AddRef()` are done
either before the node is added to `CConnman::vNodes` or while holding
`CConnman::cs_vNodes` and the object being in `CConnman::vNodes`.
So, the object being in `CConnman::vNodesDisconnected` and its reference
count being zero means that it is not and will not start to be used by
other threads.
So, the lock of `CNode::cs_vSend` in `CConnman::DisconnectNodes()` will
always succeed and is not necessary.
Indeed all locks of `CNode::cs_vSend` are done either when the reference
count is >0 or under the protection of `CConnman::cs_vNodes` and the
node being in `CConnman::vNodes`.

Pull request description:
As described in https://github.com/bitcoin/bitcoin/issues/20620 multisigs are currently limited to 16 keys in descriptors and RPC helpers, even for P2WSH and P2SH-P2WSH.
This adds support for multisig with up to 20 keys (which are already standard) for Segwit v0 context for descriptors (`wsh()`, `sh(wsh())`) and RPC helpers.
Fixes https://github.com/bitcoin/bitcoin/issues/20620
