Nasti Puts: decode wmask to determine addr_byte() and op_size()
...
This change is TL0 specific; TL2 knows the op_size, and can use
this to do a much simpler one-hot decode of the address.

Refactor the TransactionTracker logic in all the L2 TileLink Managers.
...
They now share common sub-transactions within traits, and use a common
set of state transitions and scoreboarding logic. Tracker allocation
logic has also been updated. No changes to external IOs or the TileLink protocol.
A new bufferless Broadcast hub is also included, but does not yet pass fuzzing checks.

Add a Smi to TileLink converter ( #59 )
...
I'm trying to get someone to attach their stuff to Rocket Chip for the
upcoming tapout. TileLink sounded too complicated, but Smi went over
well. Since the mmioNetwork in Rocket Chip is based on TileLink, it
seemed like the easiest thing to do was to write a TileLink to Smi
converter so people could use it.
It turns out there was already one inside the groundtest unit tests, so
I just moved that into uncore (it was inlined into a test case so you
couldn't actually use it before). Internally the converter uses Nasti,
but I figured that's good enough for now.

tilelink: wmask was double the width it should be
...
When amo_offset = UInt(0), UIntToOH(amo_offset) = "b01", not b"1".
This meant that the amo wmask was double wide, making wmask() fat.
