Various paranoia checks:
	gssd_proc.c: pass max_field sizes to sscanf to avoid buffer
	  overflow
	svcgssd_proc.c: range_check name.length, to ensure name.length+1
	  doesn't wrap
	idmapd.c(nfsdcb): make sure at least one byte is read before
	 zeroing the last byte that was read, otherwise memory corruption
	 is possible.
