On ack Icinga first adds a comment, then acks the checkable
so the ack event has the comment ID.
But due to the yet missing ack the comment was missing is_sticky.
That's corrected now.
Icinga DB doesn't expect comment history for ack comments.
Before:
1. Acked checkable recovers
2. Icinga clears ack comments w/o setting removal time
3. Icinga DB gets neither removal time, nor expire time
4. Icinga DB falls back to NULL and violates NOT NULL constraint
If comments get removed in unintended ways (i.e. not by expiring or by using
the remove-comment API action), the comment object misses information to create
a proper history event for Icinga DB. Therefor, discard these events.
icinga::Array requires locking by the caller when iterating using Begin() and
End(). This is only checked in debug builds but there it makes this function
fail.
This commit changes the Checkable notification suppression logic (notifications
are currently suppressed on the Checkable if it is unreachable, in a downtime,
or acknowledged) to that after the suppression reason ends, a state
notification is sent if and only if the first hard state after is different
from the last hard state from before. If the checkable is in a soft state after
the suppression ends, the notification is further suppressed until a hard state
is reached.
To achieve this behavior, a new attribute state_before_suppression is added to
Checkable. This attribute is set to the last hard state the first time either a
PROBLEM or a RECOVERY notification is suppressed. Compared to from before,
neither of these two flags in the suppressed_notification will ever be cleared
while the supression is still ongoing but only after the suppression ended and
the current state is compared with the old state stored in
state_before_suppression.
to ensure Checkable#IsReachable() returns correctly for dependency children inside OnReachabilityChanged().
That needs the dependency parent to be already in the correct state.

StateChangeHandler() is the function used when the actual hard/soft state
changes and thus also writes state history. This is not desired in this case,
instead, a runtime update should be generated, therefore call UpdateState()
instead.

Previously, both funktions did related operations but had unclear and confusing
naming:
- UpdateState updated the icinga:{host,service}:state Redis keys.
- SendStatusUpdate sent a runtime update for the icinga:{host,service}:state.
This commit merges both functions into one with a new mode parameter. The
following modes are now supported:
- Volatile: Update the icinga:{host,service}:state Redis key.
- Full: Perform the volatile state update and in addition send a corresponding
runtime update so that this state update gets written through to the
persistent database by a running icingadb process.
- RuntimeOnly: Special mode for callers that can ensure that a volatile update
for the current state was already performed but has to be upgraded to a full
update.

When there are multiple active IDO instances on the same node, before this
commit, all of them would share a single DbValue object for the notification_id
column of the icinga_contactnotifications table. This resulted in the issue
that one database references the notification_id in another database.
This commit fixes this by using a separate DbValue value for each IDO instance.
This needs a new signal as the existing OnQuery and OnMultipleQueries signals
perform the same queries on all IDO instances, but different queries are needed
here per instance (they only differ in the referenced DbValue). Therefore, a
new signal OnMakeQueries is added that takes a std::function which is called
once per IDO instance and can access callbacks to perform one or multiple
queries only on this specific IDO instance.
This change fixes two problems:
* The internal functions used by ScriptFunc more or less expect to operate on
full days, but ScriptFunc may have called them with some random timestamp
during the day. This is fixed by always using midnight of the day as
reference time.
* Previously, the code advanced a timestamp to the next day by adding 24 hours.
On days with DST changes, this could either still be on the same day (a day
may have 25 hours) or skip an entire day (a day may have 23 hours). This is
fixed by using a struct tm to advance the time to the next day.
m_DataBuffer may be modified concurrently while StatsFunc() is called, thus
it's unsafe to call size() on it. As write access to m_DataBuffer is already
synchronized by only modifying it from the single work queue thread, instead of
adding a mutex, this commit adds a new std::atomic_size_t which is additionally
updated when modifying m_DataBuffer and can safely be accessed in StatsFunc().
