When ReloadTorrcOnSIGHUP=1, do non-reload activities anyway

Browse Source 
Previously, we skipped everything that got invoked from
options_init_from_torrc.  But some of the stuff in
options_act_reversible and options_act is actually important, like
reopening the logs.

Now, a SIGHUP always makes the effects of an options_set() happen,
even though the options haven't changed.

Fix for bug 5095; bugfix on 0.2.1.9-alpha, which introduced
__ReloadTorrcOnSIGHUP.

o Minor bugfixes:
- When we receive a SIGHUP and the controller-use __ReloadTorrcOnSIGHUP
option is set to 0, perform other actions that SIGHUP usually causes
(like reopening the logs). Fixes bug 5095; bugfix on 0.2.1.9-alpha.
