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
