Initialise Mongoose manager. Side effect: ignores SIGPIPE signal.
`mgr->user_data` field will be initialised with a `user_data` parameter.
That is an arbitrary pointer, where the 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.
