Initialize Mongoose manager. Side effect: ignores SIGPIPE signal. mgr->user_data field will be initialized with user_data parameter. That is an arbitrary pointer, where user code can associate some data with the particular Mongoose manager. For example, a C++ wrapper class could be written, in which case user_data can hold a pointer to the class instance.
