Ian Lance Taylor fb4b4342fe os, net, internal/poll: return consistent error for closed socket ... In the past we returned "use of closed network connection" when using a closed network descriptor in some way. In CL 36799 that was changed to return "use of closed file or network connection". Because programs have no access to a value of this error type (see issue #4373) they resort to doing direct string comparisons (see issue #19252). This CL restores the old error string so that we don't break programs unnecessarily with the 1.9 release. This adds a test to the net package for the expected string. For symmetry check that the os package returns the expected error, which for os already exists as os.ErrClosed. Updates #4373. Fixed #19252.
