MFC 252205:
If daily_status_security_inline is set, the rc value needs to be
forced to 3 so that the output of this script is always displayed.
In fact, setting this flag is identical to setting
daily_status_security_output to an empty string.  To make the logic
less confusing, change the behavior of daily_status_security_inline
such that it just forces daily_status_security_output to an empty
string and then applies the normal logic.

MFC r251887:

Add new FOREACH_FROM variants of the queue(3) FOREACH macros which can
optionally start the traversal from a previously found element by passing the
element in as "var". Passing a NULL "var" retains the same semantics as the
regular FOREACH macros.
