      event: Avoid possible blocking in the listener thread when shutting down · df4fbcf4

      connections. PR 60956.

start_lingering_close_nonblocking() now puts connections in defer_linger_chain
which is emptied by any worker thread (all atomically) after its usual work,
hence the possibly blocking flush and lingering close run outside the listener.

The listener may create a dedicated worker it fills defer_linger_chain or while
it's not empty, calling push2worker with a NULL cs.

The state machine in process_socket() slighly modified to be able to enter with
CONN_STATE_LINGER directly w/o clogging_input_filters to possibly interfer.

New abort_socket_nonblocking() allows to reset connections when nonblocking is
required and we can't do much about the connection anymore, nor want the system
to linger on its own after close().

Many thanks to Stefan Priebe for it heavy testing on many event's changes!

      mpm_winnt: Advertise support for preshutdown notifications in the service, · 70c97d70

      and perform shutdown in respond to SERVICE_CONTROL_PRESHUTDOWN.

The pure shutdown notification leaves a small amount of time for the service
to finish (and the allowed amount of time has been shrinking with every new
version of Windows), and handling only it increases the chance of the process
being killed by SCM, instead of gracefully shutting down.  Handling the
preshutdown control code extends this period, and increases the chances of
finishing everything properly when the machine is rebooted or shut down.

(See https://msdn.microsoft.com/en-us/library/windows/desktop/ms683241)

Please note that although the preshutdown notifications are available only
starting from Windows Vista, the code is compatible with the previous versions
of Windows, since the SCM ignores unknown SERVICE_ACCEPT codes, and will
still send an ordinary SERVICE_CONTROL_SHUTDOWN under old Windows
versions.
