4bd4c7caf3 mdns: fix ignoring mdns packet with some invalid name entries in question field
In case of invalid name entry, only this entry is invalidated and parsing continues as other query entries could contain questions to be responded to

67051a286b mdns: fix possible crash when packet scheduled to transmit contained service which might have been already removed
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

eef0b5090a mdns: use binary semaphore instead of mutex when searching
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.

e5e2702ca3 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.
