Dictionaries with reference counters and full deletion support during traversal (#13195)
* dont use atomic operations when not needed; detect misuse of the the unsafe functions
* use relaxed atomic operations for statistics
* use relaxed atomic operations for statistics
* dictionaries now use reference counters, allowing deletetions of any item while traversing it
* added acquire/release interface to dictionaries
* added unittest for reference counters
* added NETDATA_INTERNAL_CHECKS logs to detect non-exclusive access to crusial parts of the dictionaries
* dictionaries cannot be deleted while there are referenced items in them - they will be deleted once the last item gets unreferenced
* cleanup
* properly cleanup released items
* maintain counters for readers and writers; defer all deletes on sorted walkthrough; cleaner internal_error();
* somewhat faster reference counters on single threaded dictionaries
* minor optimizations; allow compiling without internal checks
