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.

5242b87e4c lib/memory: rework allocators to make them extensible and more abstract 
This is change renders memory allocators only dependend on an address
space id that they are managing, allowing easy implementation of other
algorithms and instantiation in memory IP blocks.

f025f5dcc7 lib/ip: read base addresses from JSON into unsigned integer 
This caused sign extension for addresses with the MSB set which is
obviously wrong since this is an address and not a number. With
Jansson, there seems to be now other way since it only supports
reading (signed) integers.

676fd9171c lib/ip: make logger a class member of IpCore 
Logging is used everywhere and there's no justification of the clutter
and runtime overhead of `aut logger = getLogger();` everywhere.

This is the case when the application is not executed as root which is
now possible, with the drawback that we cannot set the IRQ affinity
anymore.
