A test for max_uri_size needed.

Also please check other settings and places in code about uri vs. url. If we're already using url everywhere, maybe it's better to name the setting max_url_length even if it's more old fashioned.

I found a sole setting with an 'url' in its name: M(URI, format_avro_schema_registry_url), also in code it's not that widely used either. I suggest to leave the name as it is.

Ok.

No idea what does it mean.

@abyss7 Now the following remains:

• get rid of ostream when writing result;
• check if zero copy data reading is possible in HTTPChunkedReadBuffer.
