allow a request to be processed in a job
Now we allow a request to be passed into a job queue, and after the job finishes the request is passed into a controller again. In order to achieve this we have a requests queue in System, when we put a request to the job this Request structure is preserved in the queue and for a new request a new Request is added to the queue. while here: - remove App::Lock()/Unlock(), use scoped locking - fix: Plugin now has a Call method which takes ModelConnector and a logger (used in multithreaded environment) - BaseThread has a main_model_connector pointer to the main (from the main thread) model connector - the FastCGI structure fcgi_request moved from App to Request - some methods for handling requests moved from App to Request - small refactoring in main.cpp - add Http class (a http client)
