Message:

Use an optional output argument instead of errno to propagate the error

The use of errno is troublesome in all other than top-level library
functions since the value in errno might get overwritten by subsequent
inner calls on the error path (e.g. cleanup, deallocation, etc.). The
optional output argument makes it possible to explicitly ignore the
error code if it is not needed, but still to pass it reliably back to
the original caller.

This change affecs async_connect_me_to(),
async_connect_me_to_blocking(), async_connect_kbox(), service_connect(),
service_connect_blocking() and loader_connect().
