-adding reset signals to synchronizer to solve startup issues
-setting config in test bench for speedup, default reg config now correct
-fix (my) stupid bug in etx_arbiter
-adding reset to fifo (todo: review this!)
-reviewing "all red" from waveforms is a must. Red (x) on data is ok, but leaving them on control signals is asking for trouble. Better safe than sorry when it comes to reset.
-Each directory contains one sub block
-Each directory contains a dv/docs/hdl directory, self contained.
-May need to add constraints directory as well at some point.
-This is the right thing to do, make each block modular and self contained.
