dns_name_packet - extract names from DNS answer packet
#include <dns.h> int dns_name_packet(stralloc* out,const char* buf, unsigned int len);
dns_name_packet is a low-level component of dns_name4, designed to support asynchronous DNS lookups. It reads a DNS packet of length len from buf, extracts the first PTR record from the answer section of the packet, puts the result into out, and returns 0 or -1 the same way as dns_name4.
