Moving to Chisel 3

[Thonner]

All of Patmos have been ported such that it compiles to chisel3. Following has been commented out - and are left to the original authors to rewrite for chisel 3:

• All black boxes
• All Chisel tests

With the porting a new emulator has been build using Verilator. To build the emulator Verilator must be installed through apt-get (instructions in README). The emulator does not yet have all features that the old emulator has. The key features will be implemented ASAP. Missing emulator features:

• Virtual network interface with IP address
• Simulate random input from keys
• Print instruction cache statistics
• Print register values in each cycle
• Read input for UART from file

Otherwise LGTM and I will merge.

Ok, then I overlooked it.
