unix_socket: add support for abstract unix domain socket
In addition to unix domain sockets, Linux also supports an
abstract namespace which is independent of the filesystem.
In order to support it, add new CURLOPT_ABSTRACT_UNIX_SOCKET
option which uses the same storage as CURLOPT_UNIX_SOCKET_PATH
internally, along with a flag to specify abstract socket.
On non-supporting platforms, the abstract address will be
interpreted as an empty string and fail gracefully.
Also add new --abstract-unix-socket tool parameter.
