Clang scan-build output

[Cliff Wells]

That's a pretty cool tool.  Surprising though that some really
simplistic stuff generated false positives, e.g.:

"Value stored to 'qclass' is never read"

 qtype = (an->type_hi << 8) + an->type_lo;
 qclass = (an->class_hi << 8) + an->class_lo;
 len = (an->len_hi << 8) + an->len_lo;
 ngx_log_debug3(NGX_LOG_DEBUG_CORE, r->log, 0,
	                  "resolver qt:%ui cl:%ui len:%uz", qtype, qclass, len);
