bdcafb9133 p2p: ProcessHeadersMessage(): fix received_new_header (Larry Ruane)
Pull request description:
Follow-up to #25717. The commit "Utilize anti-DoS headers download strategy" changed how this bool variable is computed, so that its value is now the opposite of what it should be.
Prior to #25717:
```
bool received_new_header{WITH_LOCK(::cs_main, return m_chainman.m_blockman.LookupBlockIndex(headers.back().GetHash()) == nullptr)};
```
After #25717 (simplified):
```
{
LOCK(cs_main);
last_received_header = m_chainman.m_blockman.LookupBlockIndex(headers.back().GetHash());
}
bool received_new_header{last_received_header != nullptr};
```

e68d380797 rpc: remove unneeded RPCTypeCheckArgument checks (furszy)
55566630c6 rpc: treat univalue type check error as RPC_TYPE_ERROR, not RPC_MISC_ERROR (furszy)
Pull request description:
Same rationale as #26039, tackling another angle of the problem.
#### Context
We have the same univalue type error checking code spread/duplicated few times:
`RPCTypeCheckObj`, `RPCTypeCheckArgument`, `UniValue::checkType`.
In the first two functions, we are properly returning an `RPC_TYPE_ERROR` while in `UniValue::checkType`
we are throwing an `std::runtime_error` which is caught by the RPC server request handler, who invalidly
treats it as `RPC_MISC_ERROR` (which is a generic error return code that provides no information to the user).
#### Proposed Changes
Throw a custom exception from `Univalue::checkType` (instead of a plain
`std::runtime_error`) and catch it on the RPC server request handler.
So we properly return `RPC_TYPE_ERROR` (-3) on every arg type error and
not the general `RPC_MISC_ERROR` (-1).
This will allow us to remove all the `RPCTypeCheckArgument` calls. As them are redundant since #25629.

a8a9ed67cc init: Abort if i2p/cjdns are chosen via -onlynet but unreachable (Martin Zumsande)
Pull request description:
If the networks i2p / cjdns are chosen via `-onlynet` but the user forgot to provide `-i2psam` / `-cjdnsreachable`, no outbound connections will be made - it would be nice to inform the user about that.
The solution proposed here mimics existing behavior for `-onlynet=onion` and non-specified `-onion`/`-proxy` where we already abort with an InitError - if reviewers would prefer to just print a warning, please say so.
The second commit adds CJDNS support to the debug-only `addpeeraddress` RPC allowing to add CJDNS addresses to addrman for testing and debug purposes. (if `-cjdnsreachable=1`)

I just spent a few hours trying to figure out why "18444" wasn't getting
me to regtest's RPC server. I'm not the sharpest tool in the shed, but I
was maybe understandably confused because "Bound to
127.0.0.1:18445" appears in the logs, which I assumed was the P2P port.
This change logs the RPC listening address, which seems like a basic
piece of information that shouldn't be buried in debug logs.

335ff98c8a Bugfix: Wallet: Wrap RestoreWallet content in a try block to ensure exceptions become returned errors and incomplete wallet directory is removed (Luke Dashjr)
Pull request description:
Bug 1: `copy_file` can throw exceptions, but `RestoreWallet` is expected to return a nullptr with a populated `errors` parameter. This is fixed by wrapping `copy_file` and `LoadWallet` (for good measure) in a `try` block, and converting any exceptions to the intended return style.
Bug 2: `util::Result` turns what would have been a `false` unique_ptr into a `true` nullptr result, which leads to nullptr dereferences in at least the 3 cases of wallet creation/loading/restoring. This is fixed by keeping the pointer as a plain `std::unique_ptr` until actually returning it (ie, after the nullptr check).

Pull request description:
As a follow-up to https://github.com/bitcoin/bitcoin/pull/25967#discussion_r959637189, this PR changes the return type of [`BaseIndex::GetName()`](fa5c224d44/src/index/base.h (L120)) to `const std::string&` instead of `const char*`. The first commit is not essential for this change, but since the code is touched and index names are commonly used to specify thread names, I've made the same update there.
No behaviour change, just refactoring to further phase out C-style strings.
Note: `util::ThreadRename()` used to take an rvalue ref, but since it then passes this to `SetInternalName()` by value, I don't think there's any benefit to having both an rvalue and lvalue ref function so I just changed it into lvalue ref. Not 100% sure I'm missing something?
