- Clear data->state.os_errno before transfer. - Explain the change in behavior in the CURLINFO_OS_ERRNO doc. - Add to the CURLINFO_OS_ERRNO doc the list of libcurl network-related errors that may cause the errno to be saved. data->state.os_errno is saved before libcurl returns a network-related failure such as connection failure. It is accessible to the user via CURLINFO_OS_ERRNO so they can get more information about the failure. Prior to this change it wasn't cleared before transfer so if a user retrieved the saved errno it could be from a previous transfer. That is because an errno is not always saved for network-related errors. Closes #xxxxx
