re-structure the OpenBSC directory layout
The new structure divides the code into a number of libraries for the BSC core functionality, MSC core functionality, Abis transport, TRAU and other bits. This doesn't introduce any functional code change but simply moves around files and alters Makefile.am accordingly. Next step would be to disentangle a lot of the inter-library dependencies and make the individual bits of code more independent.
