8c7d469a95 Revert "async_queue: Give names to all the registers which show up in the queue (#390)" 
This reverts commit a84a961a39.

The changes to RegisterCrossing.scala were unneeded after application of this branch.
The name changes made to the AsyncQueue.scala are reapplied at the end of this branch.

7f429e8799 Simplify AsyncResetReg 
No need for AsyncSetReg, as AsyncResetReg can be used exclusively with
inverted inputs.

a84a961a39 async_queue: Give names to all the registers which show up in the queue (#390) 
This is to aid debugging but even more so for backend constraint writers, who generally
need predictable names for registers to set false paths, etc.

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
