- remove GSI_SOCKET_read_buffer(), as it duplicates the same   functionality as GSI_SOCKET_read_token() - in GSI_SOCKET_read_token(), try to read only one token if possible,   by looking for VERSION and if found, scanning to the end of the   string, and stashing anything beyond that for for a later call. - in GSI_SOCKET_credentials_init_ext(), don't need to create an   SSL_CREDENTIALS structure - in GSI_SOCKET_get_creds(), no need to load/decrypt the   credential.  just send it directly. - don't need MYPROXY_CONTINUE in MYPROXY_RETRIEVE_CERT protocol
