+Initialise Mongoose manager. Side effect: ignores SIGPIPE signal.
+`mgr->user_data` field will be initialised with a `user_data` parameter.

 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.
