c15189b74b common/memory: implement freeing for LinearAllocator 
This is still very simple. Only really free memory, when all allocation
have been deallocated so we only need to keep track of the current
number of allocations.

13fd3f3c2a gpu: implement basic GPU plugin that can do DMA to and from its memory 
Using CUDA, memory can be allocated on the GPU and shared to peers on
the PCIe bus such as the FPGA. Furthermore, the DMA on the GPU can also
be used to read and write to/from other memory on the PCIe bus, such as
BRAM on the FPGA.

7dcdfaccd9 ips/dma: let user deal with making memory accessible to DMA 
It is probably too costly to do (and verify) it on every read
or write. Furthermore, the user knows better how to make a certain
memory available to the DMA.

89b5169a6e ips/pcie: parse AXI/PCI BARs and create mappings to/from PCIe address space 
This is used for translations that don't use VFIO which used to bridge
the PCIe address space by creating direct mappings from process VA to
the FPGA. When we want to communicate directly via PCIe without the
involvment of the CPU/VFIO, we need the proper translations that are
configured in the FPGA hardware.

105f47d2d0 common/memory: add check-callback to getPath() to select desired path 
This is a workaround until we have a better heuristic (maybe shortest
path?) to choose between multiple paths in the graph. Since the (abstract)
graph has no idea about memory translations, getPath() may even yield
paths that are no valid translation because a pair of inbound/outbound
edges must not neccessarily share a common address window, but from the
perspective of the abstract graph present a valid path.
The callback function is used by the MemoryManager to verify if a path
candidate represents a valid translation.

5b8f573337 json: parse 64bit numbers, this is required for numbers > 2^31 
Our current JSON library jansson only parses signed integers, so
it cannot correctly parse numbers between 2^31 and 2^32 into a
32 bit type.
