More GCC-related fixes in kde@ ports

Change cmake default behaviour to outsource.

Ports that build out of source now simply can use "USES=cmake"
instead of "USES=cmake:outsource". Ports that fail to build
out of source now need to specify "USES=cmake:insource".

I tried to only set insource where explictely needed.

Update KDE Applications to 18.12.0

https://www.kde.org/announcements/announce-applications-18.12.0.php

Update ImageMagick to 6.9.10.14 [1]

* Add PKGNAMESUFFIX and rename the directory. This was done to show
  that IM6 is not the "main" version. But still fully supported by upstream.
* Convert a number of options to optionhelpers.
* Add option for ISO/IEC 23008-12:2017 HEIF suport
* Add comment to pkg-descr explaining IM6's "legacy" tag.
* Add comment to the patch-config_policy.xml file why it still needed.

Please note that IM7 is not a drop in replacement due to library API and
command arguments changes. And as a result ports need to decide for themself
which version to use.

Chase these changes in all the ports that using IM6.

concurrently accessed by another application, nothing critical.

Update KDE Applications to 18.04.2

Update KDE Applications to 18.04.1

Update KDE Applications to 18.04.0

* Pin multimedia/kdelive at 17.12.3 until we import the mlt update from the
dev-repo.

Pre-emptively fix audio/kwave before CMake 3.11.

The newer CMake respects CMAKE_REQUIRED_LIBRARIES in places that older
CMake code doesn't expect. Temporarily reset to empty for that. No
effect on CMake 3.10, which didn't use that variable in CHECK_INCLUDE_FILES
anyway.
