	* zserv.c (zebra_client_read): Fix bug: first read attempt should
	  read ZEBRA_HEADER_SIZE minus the number of bytes already read.
	  Improve efficiency by maintaining a calculation of the number
	  of bytes read instead of calling stream_get_endp multiple times.
	  If message length is too small, issue a warning message (not debug)
	  before closing the connection.  And also check that message length
	  is not too big.
