There's no point in calling setpgid() on short-lived processes, so
remove the setpgid() calls when spawning dispatcher scripts, iptables,
iscsiadmin, and netconf.
config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
Especially now that we have the 'pre-up.d/' and 'pre-down.d/' directories,
silently skip over any sub directories inside the dispatcher directory.
Fixes warning:
nm-dispatcher: Cannot execute '/etc/NetworkManager/dispatcher.d/pre-up.d': not a regular file.

To ensure that NetworkManager does not block needlessly for events
which have no scripts, require scripts that respond to blocking
events to opt into the action.
If there are no dispatcher scripts, don't bother dispatching any
events. This saves some time configuring networking if the event
would have no effect anyway.
