Notification objects can refer User and Group objects similar to how they can
refer Host and Service objects, so that dependency feels quite natural. Note
that for evaluating most configuration, this order doesn't really matter, the
configuration will successfully evaluate in either case, the difference can be
noticed mainly in more advanced configurations, for example when dynamically
assigning user based on their groups. When accessing user objects from the
Notification object definition (like in the following example), without this
change, only groups configured directly in groups attribute of User objects are
visible and those added via assign clauses in UserGroup objects are missing.
With this commit, these are also visible.
apply Notification "n" to Host {
for (var u in get_objects(User)) {
log(u.name + " -> " + Json.encode(u.groups))
}
# [...]
}
A second abort() is needed at the end of `SigAbrtHandler()` to trigger the SIG_DFL action (in this case the core dump).
Also since `AttachDebugger()` disables the ability to dump core, so
it gets reenabled after returning from it.
f isn't used otherwise in the function, so if possible, it can just be moved into the lambda, avoiding a copy.

not just boost::coroutines::detail::forced_unwind.
This is needed because as of Boost 1.87, boost::asio::spawn() uses Fiber, not Coroutine v1.
https://github.com/boostorg/asio/commit/df973a85ed69f021
This is safe because every actual exception shall inherit from std::exception. Except forced_unwind and its Fiber equivalent, so that `catch(const std::exception&)` doesn't catch them and only them.
The timestamps used both in the CheckerComponent and Checkable debug
logs were printed in the scientific notation, making them effectively
useless.

Switching to std::fixed actually shows the complete Unix timestamp.

CMake 3.4 introduced a new policy [^1] which prevents from automatically
adding the compiler flags needed for exporting the symbols of the
executables and libraries without the `ENABLE_EXPORTS` property. So, by
defining this variable, CMake will restore the previous behaviour by
automatically adding the `ENABLE_EXPORTS` properties to all targets.

CMake version `< 3.5` is no longer supported, so the new CMake minimum
policy version is set to `3.8` to support C++17 unconditionally. After
checking all the policies that might affect Icinga 2 in any way, CMake
`3.17` is used as a max supported CMake policy. Anything above that may
work but we didn't explicitly verify the policies introduced with CMake
3.18 and later and may or may not affect Icinga 2.
The just merged Alpine CI run for LibreSSL from #9949 failed since it
missed the changes of the refactoring PR #10369. This change applied the
refactoring for Alpine as well, hopefully making the CI happy.
So far, Service::GetSeverity() only considered the state of its own host, i.e.
the implicit service to its own host dependency, and treated it similar to
acknowledgements and downtimes. In contrast, Host::GetSeverity() considered
reachability and treated it like a state, i.e. for the severity calculation,
the host was either up, down, or unreachable.
This commit changes the following things:
1. Make the service severity also consider explicitly configured dependencies
by using IsReachable().
2. Prefer acknowledgements and downtimes over unreachability in the severity
calculation so that if an already acknowledged or in-downtime services (i.e.
already handled service) becomes unreachable, it shouln't become more
severe.
3. To unify host and service severities a bit, hosts now use the same logic
that treats reachability more like acknowledgements/downtimes instead of
like a state (changing the other way around would the state from the check
plugin would not affect the severity for unrachable services anymore).
No change in functionality. The first two branches actually set the final
return value for the method, so they can just return directly, removing the
need to have the rest of the function inside an else block.

This prevents the use of DependencyGroup for storing the dependencies during
the early registration (m_DependencyGroupsPushedToRegistry = false),
m_PendingDependencies is introduced as a replacement to store the dependencies
at that time.
