Restructure step 1: moved async & common files into new directory structure
Moving stuff arround, step 2...
Restructuring, step 3: Test cases now contain a config.mk which is
included by the simulation makefile
Test case resembling the old test2 from the asynchronous simulation
Makefile
cleanup step 4,  generic testbenches stopping after all data has been sent
remove the now obsolete test benches
current state of the pnr scripts, now partially supporting linked pipelines (wip)
lef files of a blackbox spm & a blackbox processor to provide something pnr actually can route to... (both are implemented in rtl for simulation)
