added more c apis and capi ssl version with capi examples (#1395)

* added more apis and ssl version with most examples * some make files ajusts * set close connection to false (7~10x better performance) in examples, added Async example with abort handler, added var in Makefile for capi library * added better comments and fixed CAPIHelloWorldASync sample * removed ssl and removed allocations * added make file * removed dynamic allocations * add rust example and rename other samples * remove make capi and make capi_examples from the main Makefile * remove capi targets from clean on main Makefile * add buffer solution for get header and some string_view values * added more Rust like sample * add void* user_data in all places with handlers * refactor to eliminate std::strncat * added SSL * added -fPIC to allow dynamic libraries to link (Python and Ruby needs) * removed uws_socket_context_options_t * removed uws_timer_t * fixed async examples * added shared library in makefile for python tests * fixed uws_res_end_without_body and added uws_get_loop_with_native * added libuv build * reverted unintended helloworld and helloworld threaded changes * cork tests * added uws_req_get_full_url, uws_req_for_each_header, uws_req_for_each_header * revert HttpResponse.h log changes * initial add for bun features (Thanks Jarred) * add uws_app_listen_domain, uws_app_listen_domain_with_options, uws_app_domain, and option to pass nullptr to http routes for dynamically removes * added uws_res_state, HttpResponse and WebSocket corkUnsafe + uncorkUnsafe * removing changes in HttpResponse and WebSocket * revert changes outside capi * new lines at the end revert * revert makefiles * revert makefiles last new line * revert makefiles last new line
