Enable "localfilesystem" UNIX domain socket for ADB.

This patch introduce "service.adb.listen_addrs", a new
string type property, while keeping the old properties.
The new property added in this patch is used to listen
on UNIX domain socket "localfilesystem".

"service.adb.listen_addrs" can be used to listen on
multiple addresses, such as tcp:5555 and tcp:5556.
It is separated by ',' (comma) character.

In the process of introducing the new socket type, the
method tcp_connect is removed and combined into
socket_spec_connect.

Without specifying using the new property, adb will
try to listen on both tcp and vsock (following the
previous implementation).

Some examples of the new property value are:
  - "tcp:5555"
  - "vsock:5555"
  - "localfilesystem:/tmp/test"
  - "tcp:5555,vsock:5555"

        adb connect localfilesystem:<path_to_socket>;
        adb -s localfilesystem:<path_to_socket> shell;
	    inside Chrome OS.
