This edits the headers in every file so the copyright notice mentions RWTH Aachen University. We also update some copyright years and fix various comments so the header is the same across all of VILLASframework.

498af9fd1c ips/dma: make read correctly wait on interrupts 
Modify villas-fpga-ctrl to fit the new behavior of Dma.
Makes reading from DMA work even when we are too slow and
only receive partial batches of BDs.

14f924b6c5 rework MemoryBlock use to make use of shared_ptr so the lifetime of the objects is properly tracked 
this fixes that the wrong order of allocating and PciCard destruction
causes an undefined state.

80af655ac5 make DMA ip unmap memory owned by itself 
unmapping of the scatter gather attribute memory was done
after the DMA destructor was called, leading to Card trying to
unmap memory that was already freed.
This lead to crashing during cleaning up.
