Those patches make tcp migration use the help functions in
qemu-socket.c for support IPv6 migration.
Changes from v1:
- split different changes to small patches, it will be easier to review
- fixed some problem according to Kevin's comment
Changes from v2:
- fix issue of returning real error
- set s->fd to -1 when parse fails, won't call migrate_fd_error()
Changes from v3:
- try to use help functions in qemu-socket.c
Changes from v4:
- introduce set_socket_error() to restore real errno
- fix connect error process
Changes from v5:
- use error class to pass socket error

- fix leak of repeatedly error_set()
- coding style fix
- fix EWOULDBLOCK process

I just updated the patchset according michael and orit's
comments. Current patch handles EWOULDBLOCK same as
migration-tcp.c. The introduced qerror strings are
basically sufficient, we can fix migration error handle
later. Thanks for your time!

Amos Kong (4):
qerror: add five qerror strings
sockets: change inet_connect() to support nonblock socket
sockets: use error class to pass listen error
use inet_listen()/inet_connect() to support ipv6 migration
