Introduce unix socket connection type

Unix socket uses different accept handler/create listener from TCP,
to hide these difference to avoid hard code, use a new unix socket
connection type. Also move 'acceptUnixHandler' into unix.c.

Currently, the connection framework becomes like following:

                   uplayer
                      |
               connection layer
                 /    |     \
               TCP   Unix   TLS

It's possible to build Unix socket support as a shared library, and
load it dynamically. Because TCP and Unix socket don't require any
heavy dependencies or overheads, we build them into Redis statically.
