[Qemu-devel] [PATCH v4 13/28] migration: rename unix.c to socket.c

["Daniel P. Berrange" <berrange@redhat.com>]

The unix.c file will be nearly the same as the tcp.c file,
only differing in the initial SocketAddress creation code.
Rename unix.c to socket.c and refactor it a little to
prepare for merging the TCP code.
