use gperf for the pluginsd/streaming parser hashtable (#15251)
* use gperf for the pluginsd parser
* simplify pluginsd_parser by removing void pointers to user
* pluginsd_split_words() with inlined pluginsd_space()
* quoted_string_splitter() now uses a map instead of a function for determining spaces
* add stress test for pluginsd parser
* optimized BITMAP256
* optimized rrdpush receiver reception
* optimized rrdpush sender compression
* renames and cleanup
* remove wrong negation
* unify handshake and disconnection reasons
* use parser_find_keyword
* register job names only for the current repertoire
