Add an implementation of reactor http server (#4946)
* reactor http server * fix * test logic * add reactor server session , use buf to cache socket buffer * add reactor example * fix: nodelay, otherwise ack will be after 50 ms * tcp reactor server support multi listener * fix: tcp reactor connection lifetime about socket * feat: add tcp reactor params * format * check http reqeust complete, dynamic size buffer in reactor * remove try catch * remove debug logger * remove debug logger * fix: should not pop in destructor * delete useless * remove cankeepalive temporarily, optimize check complete req * coding style * coding style * reactor server session unit test * http reactor time server add delay param * optimize switch case, and pop completed msg in destructor * refactor reactor server session * fix: check completed request when headers are in lower case like oha, add unit tests * fix auto_ptr compile error, remove logger and coding style * compile and tests fix, add reactor obj in makefile and vcxproj * compile and tests fix in win, add reactor sample vcxproj * compile and tests fix in macos when visibility is hidden
