ruby: eliminate type uint64 and int64

These types are being replaced with uint64_t and int64_t.

ruby: replace Address by Addr
This patch eliminates the type Address defined by the ruby memory system.
This memory system would now use the type Addr that is in use by the
rest of the system.

ruby: eliminate type Time
There is another type Time in src/base class which results in a conflict.

Ruby: Remove RubyEventQueue
This patch removes RubyEventQueue. Consumer objects now rely on RubySystem
or themselves for scheduling events.

ruby: get "using namespace" out of headers
In addition to obvious changes, this required a slight change to the slicc
grammar to allow types with :: in them. Otherwise slicc barfs on std::string
which we need for the headers that slicc generates.

ruby: continue style pass

ruby: Make ruby #includes use full paths to the files they're including.
This basically means changing all #include statements and changing
autogenerated code so that it generates the correct paths. Because
slicc generates #includes, I had to hard code the include paths to
mem/protocol.

ruby: Renamed Ruby's EventQueue to RubyEventQueue

ruby: Import ruby and slicc from GEMS

We eventually plan to replace the m5 cache hierarchy with the GEMS
hierarchy, but for now we will make both live alongside eachother.
