6bf6e9fd9d net: change CreateNodeFromAcceptedSocket() to take Sock (Vasil Dimov)
9e3cbfca7c net: use Sock in CConnman::ListenSocket (Vasil Dimov)
f8bd13f85a net: add new method Sock::Accept() that wraps accept() (Vasil Dimov)
Pull request description:
_This is a piece of https://github.com/bitcoin/bitcoin/pull/21878, chopped off to ease review._
Introduce an `accept(2)` wrapper `Sock::Accept()` and extend the usage of `Sock` in `CConnman::ListenSocket` and `CreateNodeFromAcceptedSocket()`.

This should make it easier for the fuzz engine to explore multisig code
paths. See discussion in https://github.com/bitcoin/bitcoin/issues/23105
The downside is that all fuzz inputs that use ConsumeScript are now
invalidated and need to be re-generated.
Another downside may be that most multisig scripts from ConsumeScript are
using likely not fully valid pubkeys.
This PR adds a fuzz test ensuring that all the different destination types
round-trip to strings (an important test given that Satoshi managed to mess
this up, having two different address types encode the same way..)
Anyway we fail this test, since both CNoDestination and NullData encode as
empty strings, and then this "decodes" as CNoDestination (and returns an
error, but the fuzztest doesn't check that). To make the fuzzer pass, I
changed NullData to encode and decode as "null".
I think this actually adds some functionality, letting you use "null" as
an "address" for sendtoaddress and createrawtransaction, thus burning the
coins and fixing #1011...but this was not my intent and we probably want
to think a bit more carefully before deliberately supporting this.
Moved implementations of `ConsumeTxMemPoolEntry`, `ContainsSpentInput`, `ConsumeNetAddr`, and the methods(open, read, write, seek, close) of FuzzedFileProvider from test/fuzz/util.h to test/fuzz/util.cpp.
* Assert when a type is missing
* Add missing WitnessV1Taproot
* Limit WitnessUnknown to version [2, 16], to avoid abiguity
* Limit WitnessUnknown to size [2, 40], to avoid invalid sizes

Move the `FuzzedSock`'s implementation from `src/test/fuzz/util.h` to
`src/test/fuzz/util.cpp`.
A separate interface and implementation make the code more readable for
consumers who don't need to (better not) know the implementation
details.
