94defe35cc mdns: fix malfuctional query_txt 
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.

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()

that the listeners remove the service from their records immediately.

4f1a856dbf cmake: Remove defaults for COMPONENT_SRCDIRS, COMPONENT_SRCS, COMPONENT_ADD_INCLUDEDIRS 
* Philosophical: "explicit is better than implicit".
* Practical: Allows useful errors if invalid directories given in components as the defaults aren't
  always used. Also trims the -I path from a number of components that have no actual include
  directory.
* Simplifies knowing which components will be header-only and which won't

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.
