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