    Description: query.c: increase recursion depth to 200.
 The recursion loop for CNAME resolution has an upper limit of 100
 iterations by default. This has proven too small in some cases where
 large CDNs are concerned. This commit increases the limit to 200.
 .
 The patch was based on the OpenWrt fix, supplied by user ylxu.
