initctl: new command 'reload NAME:ID' and new semantics for restart

Browse Source 
This patch corrects a logical glitch, or design flaw, in initctl.  The
'restart FOO' command did not stop+start FOO only send SIGHUP (provided
FOO supports SIGHUP).  Hence, a new command 'reload FOO' is introduced,
which does exactly that, and 'restart FOO' now stops and restarts FOO.
