Those patches updated help functions in qemu-socket.c,

Applied all.  Thanks.

I tended to agree with Paolo that lack of IPv6 support is a bug at this point...

Changes from v1:
- split different changes to small patches, it will be easier to review

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:

Changes from v6:
- merge error process and nonblock support together

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
