configure: test for unix domain sockets (Matthew Zipkin) Pull request description: Closes https://github.com/bitcoin/bitcoin/issues/27252 UNIX domain sockets are a mechanism for inter-process communication that are faster than local TCP ports (because there is no need for TCP overhead) and potentially more secure because access is managed by the filesystem instead of serving an open port on the system. There has been work on [unix domain sockets before](https://github.com/bitcoin/bitcoin/pull/9979) but for now I just wanted to start on this single use-case which is enabling unix sockets from the client side, specifically connecting to a local Tor proxy (Tor can listen on unix sockets and even enforces strict curent-user-only access permission before binding) configured by `-onion=` or `-proxy=` I copied the prefix `unix:` usage from Tor. With this patch built locally you can test with your own filesystem path (example): `tor --SocksPort unix:/Users/matthewzipkin/torsocket/x` `bitcoind -proxy=unix:/Users/matthewzipkin/torsocket/x` Prep work for this feature includes: - Moving where and how we create `sockaddr` and `Sock` to accommodate `AF_UNIX` without disturbing `CService` - Expanding `Proxy` class to represent either a `CService` or a UNIX socket (by its file path) Future work: - Enable UNIX sockets for ZMQ (https://github.com/bitcoin/bitcoin/pull/27679) - Enable UNIX sockets for I2P SAM proxy (some code is included in this PR but not tested or exposed to user options yet) - Enable UNIX sockets on windows where supported - Update Network Proxies dialog in GUI to support UNIX sockets ACKs for top commit: Sjors: re-ACK567cec9a05

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt
(GUI) orbin/bitcoind
(headless)
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
