Poco logging streams are not thread safe

Description

The stream buffer within Poco keeps a string buffer of all content passed to it until it reaches an EOL character. Writing to this buffer isn't protected by a mutex and as a result logging with the streams results in a crash when a loop is parallelized.

(In [4285]) Added a thread-safe logging stream which is compatible with our logging in our threaded loops. It is still not a good idea to log too heavily in parallized loops but at least this way it is safe. Re #1201

(In [4286]) Fix for systems without compiler that supports OpenMP. Re #1201
