Vec considered harmful; use isOneOf instead ( #64 )
...
Vec is heavyweight and really should only be used for I/O and
dynamic indexing. A recurring pattern in uncore is
Vec(const1, const2, const3) contains x
which is nice but has a deleterious effect on simulation copilation
and execution time. This patch proposes an alternative:
x isOneOf (const1, const2, const3)
x isOneOf seqOfThings
I think it's also more idiomatic.
This is just a prototype; I'm not wed to the name or implementation.

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.
