vcl: new vcl api to get detailed session errors

Sometimes VPP rejects application connection requests due to various reasons. Some errors application can retry to get a successful connection. In a non-blocking session, VCL sends EPOLLHUP. An application can call a new API vppcom_session_get_error to find the details and retry depending on the error. Type: fix Signed-off-by: Radha krishna Saragadam <krishna_srk2003@yahoo.com> Change-Id: If0e21a8e25701f66a190a2799b2209e0c31f897c
