09afbbafdb ahb: weaken RegisterRouter assertion 
As written I think it could potentially fail, but what I actually care
about is something weaker that should be true. Assert: nothing lost.

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.

Also, minor code cleanup.

0baa1c9a45 coreplex: CacheBlockOffsetBits was wrong! 
This bug is ancient. I don't understand how it never mattered before.
Anyway, in processors with a custom CacheBlockBytes, this value is wrong!
The symptom is that TL1 components end up missing high address bits.
This causes, for example, a system to jump to 0 instead of RAM.

I don't understand how this very serious bug did not cause problems before.
