/* creates the listening socket, bind, applies options; waits for incoming
connection, checks its source address and port. Depending on fork option, it
may fork a subprocess.
pf specifies the syntax expected for range option. In the case of generic
socket it is 0 (expecting raw binary data), and the real pf can be obtained
from us->af_family; for other socket types pf == us->af_family
Returns 0 if a connection was accepted; with fork option, this is always in
a subprocess!
Other return values indicate a problem; this can happen in the master
process or in a subprocess.
This function does not retry. If you need retries, handle this in a
loop in the calling function (and always provide the options...)
after fork, we set the forever/retry of the child process to 0
