Remove hack using existance of an 'identity' string to disable auth
Currently the server determines whether authentication of clients is complete, by checking whether an identity is set. This patch removes that lame hack and replaces it with an explicit method for changing the client auth code * daemon/remote.c: Update for new APis * src/libvirt_private.syms, src/rpc/virnetserverclient.c, src/rpc/virnetserverclient.h: Remove virNetServerClientGetIdentity and virNetServerClientSetIdentity, adding a new method virNetServerClientSetAuth.
