31716a4960 mdns: fixed crash on free undefined ptr after skipped strdup 
Shortcircuit evaluation may cause skip of _mdns_strdup_check of any further question field, which after clear_rx_packet freed undefined memory.

9237110c5c bugfix: mdns_service_txt_set() wasn't allocating memory for TXT records 
Allocation was happening later, causing possible use of stack variables
of caller function, which could be invalid.

8dbf96a471 mdns: Minor fix for mdns_service_remove() 
Send the Goodbye packet while removing an mDNS service as an "Authoritative" packet so
that the listeners remove the service from their records immediately.

6e24566186 components/mdns: wrong Message compression detect 
Old behavior assumes message compressed when any of 2 most significant bits are set,
But in fact Message compressed only when both those bits are set to 1.

Also maximal label length should be 63 bytes.
