6029424eff Consistently use Atomic, and not std::atomic 
Atomic enforces usage of its only safe constructor,
in contrast to std::atomic.

"The default-initialized std::atomic<T> does not contain
a T object, and its only valid uses are destruction and
initialization by std::atomic_init, see LWG issue 2334."

907f41bae4 Use perfect-forwarding references to prevent passing temporaries 
Without this change, it is easy to pass a temporary, for example a vector
returned by a function to ParallelFor(). With this commit a type-constraint
is added to disable the use of this function for rvalue sequences.

An alternative would have been to capture rvalue-references in the function,
but that would have made the function unnecessarily complex, involving tuple-capture
and `shared_ptr`s, while it is usually easy to control lifetime at the call-site.

eb97638743 Make retrieval of the vector size more generic 
This also enables the use of the function with "containers" that
don't have a size function but implement an overload for `std::size()`,
like c-arrays with fixed sizes.

91c7e60df8 Replace all existing copyright headers with SPDX headers 
I've used the following command to replace the original copyright header
lines in a C-style comment block:

```
$ find . \( -type d \( -name '\..*' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f -exec perl -pi -e 's{/\*[^*]*\(\s*c\s*\)\s*(\d{4})\s*Icinga\s+GmbH[^*]*\*/}{// SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n// SPDX-License-Identifier: GPL-2.0-or-later}gi' {} +
```

For files that use shell-style comments (#) like CMakeLists.txt, I've
used this command:

```
$ find . \( -type d \( -name '\..*' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f -exec perl -pi -e 's{#.*\(\s*c\s*\)\s(\d{4})\sIcinga\s+GmbH.*}{# SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n# SPDX-License-Identifier: GPL-2.0-or-later}gi' {} +
```

And for SQL files:

```
$ find . \( -type d \( -name '\..*' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f \( -name '*.sql' \) -exec perl -pi -e 's{--.*\(c\)\s(\d{4})\sIcinga\sGmbH.*}{-- SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n-- SPDX-License-Identifier: GPL-2.0-or-later}gi' {} +
$ find . \( -type d \( -name '\..*' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f \( -name '*.sql' \) -exec perl -pi -e 's{-- Copyright \(c\)\s(\d{4})\sIcinga\s+Development\sTeam.*}{-- SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n-- SPDX-License-Identifier: GPL-2.0-or-later}gi' {} +

3d363854e2 Disable stack traces for WQ exceptions (used in config compiler) 
The ConfigItem class collects exceptions and reports them.
In contrast to our other DiagnosticInformation() calls,
verbosity is enabled any time.

This patch allows to re-enable the verbose output including
the stack traces, but disables this by default.

149f640fd8 Improve DB IDO HA failover behaviour 
- Decrease Object Authority updates to 10s (was 30s)
- Decrease failover timeout to 30s (was 60s)
- Decrease cold startup (after (re)start) with no OA updates to 30s (was 60s)
- Immediately connect on Resume()
- Fix query priority which got broken with #6970
- Add more logging when a failover is in progress

```
[2019-03-29 16:13:53 +0100] information/IdoMysqlConnection: Last update by endpoint 'master1' was 8.33246s ago (< failover timeout of 30s). Retrying.

[2019-03-29 16:14:23 +0100] information/IdoMysqlConnection: Last update by endpoint 'master1' was 38.3288s ago. Taking over 'ido-mysql' in HA zone 'master'.
```

- Add more logging for reconnect and disconnect handling
- Add 'last_failover' attribute to IDO*Connection objects
