DEV: poll: make the connect() step an action as well
Now the connect() step becomes an action. It's still implicit before
any -c/-s but it allows the listener to close() before connect()
happens, showing the polling status for this condition:
$ dev/poll/poll -v -l clo -c pol
#### BEGIN ####
cmd #1 stp #1: do_clo(3): ret=0
cmd #2 stp #0: do_con(4): ret=-1 (Connection refused)
cmd #2 stp #1: do_pol(4): ret=1 ev=0x14 (OUT HUP)
#### END ####
which differs from a case where the server closes the just accepted
connection:
$ dev/poll/poll -v -s clo -c pol
#### BEGIN ####
cmd #1 stp #0: do_con(4): ret=0
cmd #1 stp #0: do_acc(3): ret=5
cmd #1 stp #1: do_clo(5): ret=0
cmd #2 stp #1: do_pol(4): ret=1 ev=0x2005 (IN OUT RDHUP)
#### END ####
It's interesting to see OUT+HUP since HUP indicates that both directions
were closed, hence nothing may be written now, thus OUT just wants the
write handler to be notified.
