Merge of r4968, r4969, r4977, r4980, r4981, r4990: geo fixes. *) Geo: improved ngx_http_geo_block() code readability. *) Geo: fixed the "ranges" without ranges case. The following configuration returned an empty value for $geo: geo $geo { ranges; default default; } *) Fixed return type of internal function that allocates radix tree nodes. *) There's no need to normalize address returned by ngx_ptocidr(). *) Geo: ensure that default entry is always present. If 0.0.0.0/32 entry was present and there was no explicit "default", we failed to add an empty string as a default value. *) Trailing whitespace fix.
