* initial webrtc setup * missing files * rewrite of webrtc integration * initialization and cleanup of webrtc connections * make it compile without libdatachannel * add missing webrtc_initialize() function when webrtc is not enabled * make c++17 optional * add build/m4/ax_compiler_vendor.m4 * add ax_cxx_compile_stdcxx.m4 * added new m4 files to makefile.am * id all webrtc connections * show warning when webrtc is disabled * fixed message * moved all webrtc error checking inside webrtc.cpp * working webrtc connection establishment and cleanup * remove obsolete code * rewrote webrtc code in C to remove dependency for c++17 * fixed left-over reference * detect binary and text messages * minor fix * naming of webrtc threads * added webrtc configuration * fix for thread_get_name_np() * smaller web_client memory footprint * universal web clients cache * free web clients every 100 uses * webrtc is now enabled by default only when compiled with internal checks * webrtc responses to /api/ requests, including LZ4 compression * fix for binary and text messages * web_client_cache is now global * unification of the internal web server API, for web requests, aclk request, webrtc requests * more cleanup and unification of web client timings * fixed compiler warnings * update sent and received bytes * eliminated of almost all big buffers in web client * registry now uses the new json generation * cookies are now an array; fixed redirects * fix redirects, again * write cookies directly to the header buffer, eliminating the need for cookie structures in web client * reset the has_cookies flag * gathered all web client cleanup to one function * fixes redirects * added summary.globals in /api/v2/data response * ars to arc in /api/v2/data * properly handle host impersonation * set the context of mem.numa_nodes
