Replace occurence of std::list by cxx::list

[bishibashiB]

Brief feature description

After finishing cxx::list and cxx::forward_list implementation with #186 the replacement of std::list is consequently the next step.

Detailed information

After replacement of std::list additional replacements might make (1)sense performance-wise or (2)for the sake of a tidy code architecture.
However, for these 'additional replacements' a discussion / agreement should take place before any code rework.
Feel free to put your opinions and hints here.
E.g. so far I can think of discussing

• RouDi (a)processes and (b)runnables mangement, in app and (c)in introspection => review and establish a picture where to utilize lists, where vectors
• Could a cxx::list replace the UsedChunkList? Would that justify a rework of code (different member function signature), would concurrency requirements not allow to do so?
• PortPool 'lists' which use cxx::vector aka FixedPositionContainer (sender/receiver/interface/applicationPortDataList, runnableDataList)
• PortIntrospection FixedSizeContainer
