Task #2697
improve FFT library flavor/version reporting
Description
With more FFT libraries supported, in particular clFFT but also ARMPL, version reporting could use some improvements.
At the moment, clFFT version is not reported anywhere; while cuFFT version can be inferred from the CUDA compiler version, it would be better to report it clearly and possibly unify it with the CPU fft library reporting.
TODO: check if ARMPL version is reported (AFAIK the name string is correctly reported with the fftw compat layer).

Just a note related to the CPU/library versioning: An important reason for writing all those things to the top of the header is to both make it easy to find and make sure we write this info right away in the execution (before we start doing anything advanced) in case mdrun crashes. In case we want information about clFFT, I think that will have to come much later.

Which version of clfft is configured is available, however. We just haven't written the code to report it.
