[Sheepdog] [PATCH 0/4] collie: fix a socket leak problem

[MORITA Kazutaka]

Current collie exhausts local ports to connect to other nodes.
It is because the ports become in TIME-WAIT state after we closed connections
and we cannot reuse them for a while (60 seconds in my environment).
In addition, there is a socket leak in the error handling path.

This patchset fixes them.
