deCONZ core performance

Various hot path components in core were refactored to improved performance and cut down temporary memory allocations by 2/3.

Replaced QList by std::vector for various ZDP and ZCL data structures.
Reuse deCONZ::ApsDataIndication when receiving messages.
Reuse deCONZ::ZclFrame when parsing ZCL payload.
Refactored various core handlers to not copy large data structures if not needed.
Make deCONZ::ApsDataConfirm a C++ POD type instead Pimpl to prevent extra heap allocation.
Replaced all uses of QDateTime by approx. 200x faster lightweight alternative in core.
Improved serial communication performance.
Improved Cluster Info panel performance.
Improved DeviceEnumerator performance.
Improved node rendering performance.

Note: This release breaks C++ ABI for the deCONZ library and requires recompilation for custom compiled plugins with latest deconz-dev package.

A special thanks to all contributors of the deCONZ Github community.
