packets scheduled to transmit are pushed to action queue and removed from tx_queue_head structure, which is searched for all remaining services and while service is removed, then service questions/asnwers are also removed from this structure. This update fixes possible crash when packet is pushed to action queue, and when service is removed, its answers are removed from tx_queue_head, but not from action queue. this could lead to a crash when the packet is poped from action queue containing questions/answers to already removed (freed) service
Closes IDF-504

mdns_search_once_t::lock is used to synchronize tasks (taken by one
task and given by the other) so it should not be a mutex.
Convert to semaphore, and rename to indicate its purpose.

when running a query for a single txt, result entries were not created and attached to result structure. this issue was introduced when fixing memory leak in txt structure, which worked correctly for PTR queries, but caused trouble for TXT query.

mdns queries did not work properly when send imeadiately after set_hostname, which cuased reinit of pcb and therefore restarted probing, so search packets were blocked until probing finished

of caller function, which could be invalid.

Send the Goodbye packet while removing an mDNS service as an "Authoritative" packet so
that the listeners remove the service from their records immediately.

Some mDNS parser have issue with zero terminated TXT lists. This fix targets to overcome this issue. Found and tested with jmdns.

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.
