[v4,13/28] migration: rename unix.c to socket.c

Commit Message

Daniel P. Berrangé March 11, 2016, 4:37 p.m. UTC

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.
