dfa61bc487 Standardize Data.holdUnless and SeqMem.readAndHold 
- Make API more idiomatic (x holdUnless y, instead of holdUnless(x, y))
- Add new SeqMem API, readAndHold, which corresponds to most common
  use of holdUnless

735e4f8ed6 diplomacy: use HeterogeneousBag instead of Vec 
This makes it possible for the bundles to have different widths.

Previously, we had to widen all the bundles passing through a node
to the widest of all the possibilities.  This would mean that if
you had two source[] fields, they end up the same.

020fbe8be9 diplomacy: make config.Parameters available in bundle connect() 
This makes it posisble to use Parameters to control Monitors.
However, we need to make all LazyModules carry Parameters.

a5ac106bb8 axi4 ToTL: fix decode error arbitration (#417) 
When selecting between error generation on R and real data on R,
correctly calculate the R backpressure.

This bug manifests when a valid request is immediately followed by
an invalid request, wedging the R channel.

d09f43c32f axi4 Bundles: add a size calculation helper 
The old version was wrong.
Inverting before the << has a different width.
This means you end up with high bits set.
