  From: Antonio Quartulli <antonio@mandelbit.com>

The init_option() function is always invoked with the second
param "init_gc" set to "true".
This makes the parameter useless and it can therefore be removed
while always taking the "true" branch in the related logic.

This way we can also drop the options->gc_owned member as it
would also be always set to true.

Well spotted... on the first glance, this was like "uh, would that be
safe?  what if anything else relies on gc_owned?", but on more thorough
reading it's really as you say - all callers pass "true", and this field
is not used anywhere ever again ("confirmed by grep and buildbot" ;-) ).

Your patch has been applied to the master and release/2.7 branch
(prerequisite for a subsequent bugfix).
