* Rename test_jconf.c to test_jconf_cpp.cpp * Parse the config file on arenas read_jconf now reads the file and builds the JSON tree in a scratch arena that is released before it returns, and copies the parsed strings into one process-lifetime arena instead of a malloc per string. parse_addr and the config parser share one address splitter. Port test_jconf to C++ and cover every field copied out of the parse tree, a re-read, and the densest file the size limit accepts. * tests: rename remaining C unit tests to .cpp (no content changes) * tests: port remaining C unit tests to the C++ test harness Convert acl, acl_literal, aead2022, base64, buffer, cache (legacy reference), crypto, ipset, ipset_reference, json, netutils, ppbloom, process, ref, ssurl and utils tests to test_helpers.hpp. ctest names are unchanged; every assertion is kept. Build the ported sources with the strict C++ warning set. * Run clang-tidy on every ported test The test regex skipped file names with digits (test_aead2022_cpp.cpp, test_base64_cpp.cpp); include them, fix the two optional accesses it then reports, and build test_jconf with the strict warning set. * docs: per-connection RSS on Linux against the C relay * test_jconf: check read_jconf results before using them
