70487a43d4 Apply patch #8854: dns: Simplify #ifdef guard around dns_gethostbyname_addrtype from Axel Lin 
+ Minor compile fix from me
Patch makes the code a tiny bit less lightweight (add a parameter in dns_gethostbyname which is then not used in dns_gethostbyname_addrtype) but it makes the code more readable.

6e863ecb50 dns: Remove always true test in dns_alloc_random_port 
The only way to exit the do-while loop is err != ERR_USE.
Thus get rid of the always true test.

668d461104 dns: Fix dns_alloc_pcb for reuse an existing one case 
The logic to use an already existing pcb is wrong because the idx never
advanced in the for loop, so it keep checking the same dns_pcbs[idx] for
each loop iteration. Fix it.

177c06b1f1 - prework for fixing bug #45029: access IPv4 configuration of struct netif via new API (netif_ip4_addr()/netif_ip4_netmask()/netif_ip4_gw()) instead of accessing the struct member directly. This way, we can change the struct member types from ip4_addr_t to ip_addr_t; 
- fixed some bugs in calls to ip4_addr*() where the cast to u8_t* did not reveal the wrong address type
