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.

This makes it posisble to use Parameters to control Monitors.

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.

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
