52bb6cd9d9 Configs: use a uniform syntax without Match exceptions (#507) 
* Configs: use a uniform syntax without Match exceptions

The old style of specifying Configs used total functions.  The only way to
indicate that a key was not matched was to throw an exception.  Not only was
this a performance concern, but it also caused confusing error messages
whenever you had a match failure from a lookup within a lookup.  The
exception could get handled by an outer-lookup that then reported the wrong
key as missing.

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.

aabd17d935 rocketchip: must create bundles within Module scope 
1. Bundles be created after base class Module constructor runs
2. Bundles must be created before Module(...) runs

Solution: pass a bundle constructor to the cake base class

Require the constructor to take a parameter so people don't use it by
accident; they should get a type error.

Consistently name all the cake arguments with an _io, _coreplex, _outer,
so that they don't shadow the base class variables you should be using.

9910c69c67 Move a bunch more things into util package 
A lot of utility code was just being imported willy-nilly from one
package to another. This moves the common code into util to make things
more sensible. The code moved were

 * The AsyncQueue and AsyncDecoupledCrossing from junctions.
 * All of the code in rocket's util.scala
 * The BlackBox asynchronous reset registers from uncore.tilelink2
 * The implicit definitions from uncore.util

c45cc76cef Get rid of remaining MemIO code 
The only thing we were still using it for was for the MIFDataBits
and MIFTagBits parameters. We replace these with EdgeDataBits and
EdgeIDBits.
